GMAT Flashcards: Quant, Verbal & Data Insights Decisions
Build quick recall for the current GMAT with 300 original cards across Quantitative Reasoning, Verbal Reasoning, and Data Insights. The deck focuses on reusable concepts and decisions; full-length practice belongs in official or properly licensed question banks.
What the cards map
- Quant maps numeric forms, terms, rules, and formulas to their meaning, conditions, or use. Short scenarios ask for the operation, equation, or answer check that fits.
- Verbal maps passage and argument cues to purpose, scope, evidence, inference, reasoning flaws, and evaluation moves.
- Data Insights maps targets, constraints, source and display cues, metrics, and evidence states to the interpretation or decision they support. It covers Data Sufficiency, Multi-Source Reasoning, Table Analysis, Graphics Interpretation, and Two-Part Analysis.
Learning order
The mixed sequence keeps all three sections in rotation. Quant foundations come before algebra, models, and strategy checks; passage reading comes before argument evaluation; shared data literacy comes before the five Data Insights formats. Closely related prompts are spaced apart so one card does not cue the next.
Current-format boundary
This deck has no geometry lessons or formula drills, Sentence Correction, or the retired Integrated Reasoning section. It also excludes timing, scoring, test-center policy, full passages, large data sets, and response-pattern tricks.
Every card is an original compact concept or decision prompt. No official or competitor questions, answer choices, explanations, mark schemes, curriculum text, logos, or trade dress were copied or adapted. See the official GMAT exam content and Data Insights preparation guidance for the current exam boundary.

Spjald 1
Spurning
Which numerator-and-denominator operation creates an equivalent fraction?
Svar
Multiply or divide the numerator and denominator by the same nonzero number. The fraction's value stays unchanged.
Spjald 2
Spurning
What does data sufficiency ask you to determine?
Svar
Whether the information guarantees one answer. You usually don’t need to calculate that answer.
Spjald 3
Spurning
How do you form a passage's main idea?
Svar
Combine the passage's central topic with its main claim about that topic. The answer should cover the whole passage at the right level.
Spjald 4
Spurning
What does multiplying a decimal by 10ⁿ do when n is a positive integer?
Svar
It moves the decimal point n places to the right. Dividing by 10ⁿ moves it n places left.
Spjald 5
Spurning
What makes information sufficient for a value question?
Svar
It forces exactly one value for the target. Different values that satisfy all conditions make it insufficient.
Spjald 6
Spurning
How do you identify the passage's primary purpose?
Svar
Name what the author is doing with the topic: explaining, comparing, challenging, defending, or proposing. Keep content and action together.
Spjald 7
Spurning
How do you find p percent of a quantity q?
Svar
Compute (p/100) × q. Translate “of” as multiplication.
Spjald 8
Spurning
How can two valid cases prove insufficiency?
Svar
Make the cases produce different answers to the question. One clean counterexample pair is enough.
Spjald 9
Spurning
How do you determine a paragraph's role?
Svar
Connect the paragraph to what comes before and after it. Decide whether it introduces, supports, qualifies, contrasts, applies, or concludes the larger discussion.
Spjald 10
Spurning
A total of 45 is split in the ratio 2:3. What are the two parts?
Svar
18 and 27. The five ratio units are worth 45 ÷ 5 = 9 each.
Spjald 11
Spurning
Why can an integer restriction change sufficiency?
Svar
It removes noninteger possibilities. A range containing many real numbers may contain only one integer.
Spjald 12
Spurning
When is a product of signed factors negative?
Svar
Provided no factor is zero, an odd number of negative factors gives a negative product, while an even number gives a positive product. If any factor is zero, the product is zero.
Spjald 13
Spurning
How should two data-sufficiency statements be tested initially?
Svar
Test each statement independently against the stem. Do not carry information from one statement into the other.
Spjald 14
Spurning
What makes an integer greater than 1 prime?
Svar
It has exactly two positive divisors: 1 and itself.
Spjald 15
Spurning
What should you do first on a detail question?
Svar
Return to the relevant lines and read their local context. Memory tends to preserve the topic while blurring qualifications.
Spjald 16
Spurning
What is the divisibility rule for 2?
Svar
The last digit must be even: 0, 2, 4, 6, or 8.
Spjald 17
Spurning
How do you test whether a fact is relevant?
Svar
Connect it to the requested target. A true fact that does not narrow the target adds no decision value.
Spjald 18
Spurning
How far may a reading inference go beyond the text?
Svar
Only as far as the text strongly supports. Prefer the smallest justified step and reject claims needing outside knowledge.
Spjald 19
Spurning
Why is prime factorization useful in GMAT arithmetic?
Svar
It exposes divisibility, factors, greatest common factors, least common multiples, and perfect powers.
Spjald 20
Spurning
What must happen before quantities with different units are combined?
Svar
First confirm that their dimensions are compatible, then convert them to a common unit. Keep the unit attached through the calculation to catch mismatches.
Spjald 21
Spurning
How do you apply a passage principle to a new case?
Svar
Extract the principle's required conditions, then test whether the new case has them. Surface similarity isn't enough.
Spjald 22
Spurning
Which relationship connects distance, rate, and time?
Svar
Distance = rate × time. Rearrange only after the units are compatible.
Spjald 23
Spurning
How do you find a least common multiple from prime factorizations?
Svar
Take every prime that appears, using the largest exponent present.
Spjald 24
Spurning
How do you multiply powers with the same base?
Svar
Add the exponents: aᵐ × aⁿ = aᵐ⁺ⁿ.
Spjald 25
Spurning
How is a weighted average computed?
Svar
Divide the total weighted value by the total weight. For groups, use group size as the weight unless another weight is given.
Spjald 26
Spurning
What should a quick passage map record?
Svar
Each paragraph's role and major viewpoint, plus the passage's overall direction. Record structure, not a sentence-by-sentence summary.
Spjald 27
Spurning
What does the principal square root symbol √x return?
Svar
For real x ≥ 0, it is the nonnegative number whose square is x. For example, √9 = 3, not ±3.
Spjald 28
Spurning
When can bounds replace exact arithmetic?
Svar
When the bounds separate the viable decisions. Stop once every value in the interval leads to the same choice.
Spjald 29
Spurning
How do you keep viewpoints separate?
Svar
Attach each claim to its speaker: author, critic, researcher, or group. Track agreement, disagreement, and any later qualification.
Spjald 30
Spurning
How do “sum,” “product,” and “quotient” translate into algebra?
Svar
They mean addition, multiplication, and division, respectively.
Spjald 31
Spurning
How do you reduce a fraction to lowest terms?
Svar
Divide the numerator and denominator by their greatest common factor.
Spjald 32
Spurning
What evidence should determine the author's tone?
Svar
Evaluative words, qualifications, and the treatment of competing views. Topic alone doesn't establish approval, concern, or skepticism.
Spjald 33
Spurning
When should rounding usually occur?
Svar
At the end, unless estimation already settles the decision. Early rounding can move a result across a cutoff.
Spjald 34
Spurning
How do you convert a terminating decimal to a fraction?
Svar
Write the digits over the matching power of 10, then reduce. For example, 0.375 = 375/1000 = 3/8.
Spjald 35
Spurning
When should you stop calculating in a sufficiency problem?
Svar
As soon as uniqueness is proved or disproved. More arithmetic cannot change the sufficiency decision.
Spjald 36
Spurning
How do you spot an out-of-scope answer?
Svar
It introduces a person, period, cause, or consequence the passage doesn't address. Being reasonable doesn't make it textually supported.
Spjald 37
Spurning
What is the percent-change formula?
Svar
For original > 0, percent change = (new − original) / original × 100%. Percent change from zero is undefined; negative baselines require context-specific interpretation.
Spjald 38
Spurning
What makes information sufficient for a yes-or-no question?
Svar
It forces the same yes-or-no answer in every valid case. The underlying value may still vary.
Spjald 39
Spurning
What preserves a ratio when its quantities are scaled?
Svar
Multiplying or dividing both terms by the same nonzero factor preserves the ratio.
Spjald 40
Spurning
How do you reject a main-idea answer with the wrong scope?
Svar
Compare it with the whole passage. A detail-only answer is too narrow; a claim extending beyond the passage is too broad.
Spjald 41
Spurning
Why should you track whether a variable is positive, negative, or zero?
Svar
Sign controls valid cases and operations. Squaring can hide sign, and division requires a nonzero denominator.
Spjald 42
Spurning
How do you simplify subtraction of a negative number?
Svar
Change it to addition: a − (−b) = a + b.
Spjald 43
Spurning
Whose purpose matters in a primary-purpose question?
Svar
The passage author's purpose. A theory or researcher may be described at length without representing what the author ultimately wants to do.
Spjald 44
Spurning
When is the on-screen calculator most useful?
Svar
For tedious arithmetic after the setup is clear. It does not replace choosing the right relationship or denominator.
Spjald 45
Spurning
In Data Sufficiency, what stem information applies when testing either statement?
Svar
Everything in the question stem. Stem facts remain active for each statement and for the combination.
Spjald 46
Spurning
What is the divisibility rule for 3?
Svar
The sum of the digits must be divisible by 3.
Spjald 47
Spurning
What does a transition paragraph often do?
Svar
It closes one line of thought and sets up the next. Its role depends on both sides, not only on its first sentence.
Spjald 48
Spurning
When is a proxy measure useful?
Svar
When evidence shows it reliably tracks the target for the intended decision. Correlation may support prediction, but it proves neither causation nor suitability on its own.
Spjald 49
Spurning
How do you find a greatest common factor from prime factorizations?
Svar
Take each shared prime to the smaller exponent.
Spjald 50
Spurning
What is the arithmetic mean?
Svar
The sum of the values divided by the number of values.
Spjald 51
Spurning
What units should a rate have?
Svar
One quantity per another, such as kilometers per hour. The denominator tells you what the rate is measured against.
Spjald 52
Spurning
How do you divide powers with the same nonzero base?
Svar
Subtract the exponents: aᵐ ÷ aⁿ = aᵐ⁻ⁿ.
Spjald 53
Spurning
What makes a paraphrase faithful to a passage detail?
Svar
It preserves the original meaning, scope, and certainty in different words. Shared keywords alone don't make it accurate.
Spjald 54
Spurning
How do you recover a total from an average?
Svar
Total = average × number of values.
Spjald 55
Spurning
How do you choose between two plausible reading inferences?
Svar
Choose the one with the tighter textual chain and fewer assumptions. Plausibility in the real world is secondary.
Spjald 56
Spurning
What quick check can catch a calculator-entry error?
Svar
Estimate the order of magnitude and direction first. An exact result far outside that range deserves another look.
Spjald 57
Spurning
How do you simplify a square root with a perfect-square factor?
Svar
Factor out the perfect square. For example, √72 = √(36 × 2) = 6√2.
Spjald 58
Spurning
What makes a new example parallel to one in the passage?
Svar
The same logical relationship. Match cause, contrast, exception, or function rather than shared subject matter.
Spjald 59
Spurning
When can work rates be added?
Svar
Add the stated constant rates when the workers operate simultaneously without interfering with one another. At 1/4 and 1/6 job per hour, together they complete 5/12 job per hour.
Spjald 60
Spurning
What is the denominator in a percent comparison?
Svar
The stated reference value. “A as a percent of B” means A divided by B, then multiplied by 100.
Spjald 61
Spurning
How do you translate “5 less than x”?
Svar
x − 5. The phrase “less than” reverses the spoken order.
Spjald 62
Spurning
In Data Sufficiency, what should you check before testing values?
Svar
The full domain. Honor stated restrictions and implicit ones such as positive lengths or nonzero divisors before judging sufficiency.
Spjald 63
Spurning
How do you add fractions with different denominators?
Svar
Rewrite them with a common denominator, then add the numerators. For example, 2/3 + 1/4 = 8/12 + 3/12 = 11/12.
Spjald 64
Spurning
How do you distinguish description from argument in a passage?
Svar
Description presents what happened or what a view says; argument gives reasons to accept, reject, or revise a claim.
Spjald 65
Spurning
How should you compare decimals with different lengths?
Svar
Append trailing zeros and compare place by place. For example, compare 0.47 with 0.4700, which are equal.
Spjald 66
Spurning
How should combined statements be evaluated?
Svar
Intersect their constraints with the stem. The combination is sufficient only if every remaining case gives one answer.
Spjald 67
Spurning
How do you find common ground between two viewpoints?
Svar
Look for the narrow claim both accept, even if they disagree about its cause, importance, or implications.
Spjald 68
Spurning
How do you solve a proportion such as a/b = c/d?
Svar
Cross-multiply to get ad = bc, provided b and d are nonzero.
Spjald 69
Spurning
How is average speed computed?
Svar
Total distance divided by total time. It is not usually the simple mean of the segment speeds.
Spjald 70
Spurning
What does |x| represent?
Svar
The nonnegative distance from x to 0 on the number line.
Spjald 71
Spurning
Why are strongly emotional tone descriptions often wrong?
Svar
They overstate measured academic prose. Match the answer's intensity to the author's actual language.
Spjald 72
Spurning
What is the divisibility rule for 4?
Svar
The number formed by the last two digits must be divisible by 4.
Spjald 73
Spurning
Can the ordinary percent-change formula be applied directly when the original value is zero or negative?
Svar
No. The ordinary GMAT rule assumes original > 0. Change from zero is undefined, and a negative baseline requires context-specific interpretation.
Spjald 74
Spurning
Why can a true statement still be a wrong answer?
Svar
It may not answer the question asked. Check the task—main idea, detail, inference, role, or purpose—before checking truth.
Spjald 75
Spurning
When must a weighted average lie between its component values?
Svar
When every weight is nonnegative and the total weight is positive. The average then lies between the smallest and largest component values.
Spjald 76
Spurning
How do you express an integer n divided by d with remainder r?
Svar
n = dq + r, where q is an integer and 0 ≤ r < d for positive d.
Spjald 77
Spurning
What does an inequality usually provide?
Svar
A range, not a unique value. It can still be sufficient if the question asks whether a threshold is crossed.
Spjald 78
Spurning
How should you handle an EXCEPT detail prompt?
Svar
Verify four statements against the passage and select the one that isn't supported. Keep the reversed task visible while checking each choice.
Spjald 79
Spurning
How should you set up a unit conversion?
Svar
Multiply by a conversion factor equal to 1, placing units so the unwanted unit cancels.
Spjald 80
Spurning
Can two individually insufficient statements remain insufficient together?
Svar
Yes. They may repeat the same limitation or still leave multiple valid answers.
Spjald 81
Spurning
For a positive base, how do you simplify a power raised to another power?
Svar
Multiply the exponents: (aᵐ)ⁿ = a^(mn).
Spjald 82
Spurning
When can you infer that an author accepts a claim?
Svar
When the author endorses it directly or relies on it without distancing language. Merely reporting another person's view isn't endorsement.
Spjald 83
Spurning
How should successive percentage changes be combined?
Svar
Multiply their factors. A 10% rise followed by a 10% fall gives 1.10 × 0.90 = 0.99, a 1% net fall.
Spjald 84
Spurning
What are compatible numbers in estimation?
Svar
Nearby numbers chosen to make mental arithmetic easy, such as 203 ÷ 9.9 ≈ 200 ÷ 10 = 20.
Spjald 85
Spurning
Which constraints are easy to overlook in a word problem?
Svar
Countability, positivity, distinctness, and capacity limits. Translate each noun and rule into a usable constraint.
Spjald 86
Spurning
How do you state the exact disagreement between two viewpoints?
Svar
Identify one claim that one side accepts and the other rejects. Don't substitute a topic that only one side discusses.
Spjald 87
Spurning
How do you represent three consecutive integers?
Svar
n, n + 1, and n + 2 for an integer n.
Spjald 88
Spurning
How do percentage points differ from percent change?
Svar
Percentage points are the direct difference between percentages. Moving from 20% to 25% is 5 points and a 25% relative increase.
Spjald 89
Spurning
What is a reversed-relationship trap?
Svar
It swaps cause and effect, support and conclusion, or the positions of two viewpoints while reusing familiar passage language.
Spjald 90
Spurning
How do you multiply two fractions?
Svar
Multiply numerator by numerator and denominator by denominator, canceling common factors when convenient.
Spjald 91
Spurning
How do direct and inverse proportion differ?
Svar
Direct:
y = kx; inverse:y = k/xforx ≠ 0.Spjald 92
Spurning
How do you recover an original value after a percentage increase?
Svar
Divide the new value by the growth factor. After a 20% increase, original = new ÷ 1.20.
Spjald 93
Spurning
When should absolute wording raise suspicion?
Svar
When the passage is qualified. Words such as always, never, entirely, and impossible require equally strong textual support.
Spjald 94
Spurning
What should you identify first in Data Sufficiency?
Svar
The exact target and answer type. Decide whether the stem asks for a value, a comparison, or a yes-or-no result.
Spjald 95
Spurning
What ending makes an integer divisible by 5 or by 10?
Svar
A last digit of 0 or 5 gives divisibility by 5; a last digit of 0 gives divisibility by 10.
Spjald 96
Spurning
How should a Data Sufficiency condition be handled?
Svar
Translate it into a precise constraint before testing sufficiency. Keep it separate from the conclusion you want.
Spjald 97
Spurning
How do you reject a half-right answer?
Svar
Test every part of it. One accurate clause can't rescue a second clause that distorts the passage or exceeds its scope.
Spjald 98
Spurning
When you convert a positive measurement to a smaller linear unit, what happens to its numerical value?
Svar
It increases. Multiply by the number of smaller units in one larger unit.
Spjald 99
Spurning
DS example: Is x > 5? Statement: x > 3. Is the statement sufficient?
Svar
No. Both x = 4 and x = 6 satisfy the statement, but they answer the stem differently.
Spjald 100
Spurning
What is a⁰ when a is nonzero?
Svar
- The nonzero-base condition matters because 0⁰ is not assigned this rule.
Spjald 101
Spurning
Which claim is the argument trying to establish?
Svar
The main conclusion. Find the claim supported by the other statements, then check that it answers the argument's central issue.
Spjald 102
Spurning
When should the two statements be combined?
Svar
When neither statement is sufficient alone. Use both constraints at once and test the remaining possibilities.
Spjald 103
Spurning
A positive number rounds to 8.2 to the nearest tenth. What interval contains it?
Svar
8.15 ≤ x < 8.25. The lower endpoint rounds up to 8.2; the upper endpoint rounds to 8.3.
Spjald 104
Spurning
What should you check when the conclusion changes populations?
Svar
Whether the evidence applies to the new population. Results from volunteers, specialists, or one age group may not transfer to everyone.
Spjald 105
Spurning
How should test values be chosen in Data Sufficiency?
Svar
Choose valid values that probe boundaries, signs, and distinct outcomes. Random easy values can miss the deciding case.
Spjald 106
Spurning
How do you translate “A is 30% more than B”?
Svar
A = 1.30B. The percentage is based on B.
Spjald 107
Spurning
When can one equation involving two variables be sufficient for a target?
Svar
When every valid solution gives the same target value, even if neither variable is unique. For example, x + y = 10 is sufficient to determine x + y.
Spjald 108
Spurning
What does a correlation establish by itself?
Svar
Only that two things vary together. It doesn't establish which one causes the other or whether a third factor causes both.
Spjald 109
Spurning
How do you divide by a nonzero fraction?
Svar
Multiply by its reciprocal. For example, 3/5 ÷ 2/7 = 3/5 × 7/2.
Spjald 110
Spurning
Why is a ratio often insufficient for an absolute value?
Svar
A ratio fixes relative size but usually leaves the scale free. Many proportional pairs can share the same ratio.
Spjald 111
Spurning
What is the divisibility rule for 9?
Svar
The sum of the digits must be divisible by 9.
Spjald 112
Spurning
What matters most when applying a sample result to a population?
Svar
Representativeness. The sample must resemble the target population on traits that could affect the result.
Spjald 113
Spurning
What should you check after solving a squared equation?
Svar
Check every allowed root. If positive and negative roots produce different target answers, the information is insufficient.
Spjald 114
Spurning
What does a negative exponent mean?
Svar
It takes the reciprocal: a⁻ⁿ = 1/aⁿ for nonzero a.
Spjald 115
Spurning
Which baseline makes a comparison informative?
Svar
The baseline relevant to the claim. Compare the outcome with what would otherwise have happened, not merely with an unrelated earlier figure.
Spjald 116
Spurning
What risk appears when an equation factors into multiple branches?
Svar
Each branch may create valid cases. Test all branches against the stem before deciding sufficiency.
Spjald 117
Spurning
How can you compare two positive fractions quickly?
Svar
Compare their cross-products. For a/b and c/d with positive denominators, compare ad with bc.
Spjald 118
Spurning
What may be assumed from a Data Sufficiency diagram?
Svar
Only marked or stated facts. Do not infer scale, equality, perpendicularity, or midpoint status from appearance.
Spjald 119
Spurning
What multiplier represents a p percent increase or decrease?
Svar
Use 1 + p/100 for an increase and 1 − p/100 for a decrease.
Spjald 120
Spurning
Which statements count as evidence?
Svar
The statements offered as reasons to accept another claim. Evidence may be factual or assumed for the argument, even if it isn't proven in real life.
Spjald 121
Spurning
Can a mean determine an individual observation?
Svar
Not by itself. A mean fixes the total, but different sets can have that total unless more constraints apply.
Spjald 122
Spurning
What weakens a move from past evidence to a present claim?
Svar
A relevant change over time. New technology, prices, rules, or behavior can make the earlier evidence a poor guide.
Spjald 123
Spurning
A value becomes 96 after a 20% increase. What was the original value?
Svar
- Divide the final value by the growth multiplier: 96 ÷ 1.2 = 80.
Spjald 124
Spurning
How do extreme valid cases help in Data Sufficiency?
Svar
They expose whether the target can change. Test the smallest, largest, or boundary cases allowed by the conditions.
Spjald 125
Spurning
How do you test for reverse causation?
Svar
Ask whether the alleged effect could instead cause the alleged cause. Productive teams may meet more because they are productive, not the reverse.
Spjald 126
Spurning
Must a sufficient statement make every variable unique?
Svar
No. It only needs to make the requested target unique, even if other variables remain undetermined.
Spjald 127
Spurning
A price rises 20% and then falls 20%. Does it return to its original value?
Svar
No. The multipliers give 1.20 × 0.80 = 0.96, so the final price is 4% below the original.
Spjald 128
Spurning
Why can a voluntary survey be biased?
Svar
People who choose to respond may differ from those who don't. Strong opinions or extra interest can distort the sample.
Spjald 129
Spurning
How do you expand a(b + c)?
Svar
ab + ac. The outside factor multiplies every term inside the parentheses.
Spjald 130
Spurning
What should the final Data Sufficiency decision describe?
Svar
Which information set guarantees an answer. It should not report the target’s numerical value.
Spjald 131
Spurning
What is the goal when solving a linear equation?
Svar
Isolate the variable by applying equivalent operations to both sides.
Spjald 132
Spurning
DS example: Is integer n even? Statement: n = 7. Is the statement sufficient?
Svar
Yes. It guarantees one answer—no. A statement can be sufficient even when that answer is negative.
Spjald 133
Spurning
When must an inequality sign reverse?
Svar
When both sides are multiplied or divided by a negative number.
Spjald 134
Spurning
What must be checked before comparing two groups?
Svar
Whether they differ in other relevant ways. Age, experience, starting level, or incentives may explain the outcome instead.
Spjald 135
Spurning
When is substitution preferable to elimination in a two-equation system?
Svar
Use substitution when one variable is already isolated or easy to isolate; use elimination when coefficients cancel easily.
Spjald 136
Spurning
What should you build before analyzing Multi-Source Reasoning material?
Svar
A quick source map. Note what each tab or document contains, who produced it, and the relevant date or scope.
Spjald 137
Spurning
How do you separate background from evidence?
Svar
Ask whether the statement supports a claim. Background sets context; evidence does logical work in moving the argument toward a conclusion.
Spjald 138
Spurning
Which algebraic terms can be combined?
Svar
Terms with the same variable part and exponents. For example, 3x² and −5x² combine, but 3x² and 3x do not.
Spjald 139
Spurning
When should you read the Multi-Source Reasoning question?
Svar
Before a deep read of every source. The question tells you which details deserve attention.
Spjald 140
Spurning
What is a reliable first step for an equation containing several fractions?
Svar
Multiply every term by the least common denominator, then solve the simpler equation.
Spjald 141
Spurning
Why does source provenance matter?
Svar
It defines what a claim can support. An internal forecast and an audited result do not carry the same evidentiary weight.
Spjald 142
Spurning
What should you test when evidence comes from a different setting?
Svar
Whether the settings differ in a way that affects the result. A finding from one market, school, or climate may not carry over unchanged.
Spjald 143
Spurning
What does an “and” compound inequality require?
Svar
The overlap of both solution sets. A value must satisfy both conditions.
Spjald 144
Spurning
What should you compare before combining claims from two sources?
Svar
Their population, period, units, and definitions. Matching labels can hide different scopes.
Spjald 145
Spurning
How can a third factor undermine a causal claim?
Svar
It may explain both events, so their correlation no longer establishes a direct causal link by itself. Hot weather can raise both cold-drink sales and pool attendance.
Spjald 146
Spurning
What do one, zero, or infinitely many solutions mean for two linear equations in two variables?
Svar
The lines intersect once, are parallel and distinct, or are the same line, respectively.
Spjald 147
Spurning
How should records from separate sources be linked?
Svar
Use a shared key with the same meaning in both sources, such as product code and month. Do not join on a vague label alone.
Spjald 148
Spurning
How do you factor 6x + 9?
Svar
3(2x + 3). Pull out the greatest common factor.
Spjald 149
Spurning
When does nonresponse threaten a survey result?
Svar
When nonrespondents may answer differently from respondents. A high response count doesn't fix a systematic missing group.
Spjald 150
Spurning
What is the first step when two sources seem inconsistent?
Svar
Compare definitions, dates, units, and aggregation levels. Many apparent conflicts come from mismatched frames.

Spjald 151
Spurning
When can you use the zero-product property?
Svar
After rewriting a product equal to zero. If (x − 2)(x + 5) = 0, then x = 2 or x = −5.
Spjald 152
Spurning
How does an inference differ from a stated fact?
Svar
A fact appears directly in a source; an inference must follow from the sources without an extra assumption.
Spjald 153
Spurning
Does a higher percentage by itself prove a higher count?
Svar
No. The underlying totals matter. Twenty percent of 1,000 is more than fifty percent of 100.
Spjald 154
Spurning
What does an “or” compound inequality require?
Svar
The union of the solution sets. A value may satisfy either condition or both.
Spjald 155
Spurning
What does a blank or omitted value establish?
Svar
Only that the value is not provided. It does not establish zero, no change, or failure.
Spjald 156
Spurning
How do you recognize an intermediate conclusion?
Svar
It is supported by one claim and supports another. It acts as both a conclusion and a premise in the same argument.
Spjald 157
Spurning
What should you do before writing equations for a two-quantity word problem?
Svar
Define each variable with its unit, then translate one independent relationship per equation.
Spjald 158
Spurning
Why should cross-source events be placed in time order?
Svar
Sequence separates prior conditions from later outcomes and prevents using future information as an earlier cause.
Spjald 159
Spurning
When should candidate solutions be checked in the original equation?
Svar
Always after a step that may introduce solutions, especially squaring both sides or clearing variable denominators.
Spjald 160
Spurning
How can switching from one measured outcome to another create a gap?
Svar
Evidence about one metric may not support a conclusion about another. More website visits, for example, don't by themselves mean more sales.
Spjald 161
Spurning
What makes a source relevant to a claim?
Svar
It supplies evidence for a required link in the claim. Related background alone is not enough.
Spjald 162
Spurning
How do you solve a factored polynomial inequality reliably?
Svar
Find the zeros, split the number line into intervals, and test each interval's sign. Include a zero only when equality is allowed.
Spjald 163
Spurning
Does happening first prove causation?
Svar
No. The timing may fit a causal story, but coincidence or another cause can still explain the later event.
Spjald 164
Spurning
How can you spot an unsupported cross-source conclusion?
Svar
Identify the bridge between evidence and conclusion. If the sources never establish that bridge, the conclusion needs an assumption.
Spjald 165
Spurning
What do 0 = 0 and 0 = 5 mean after simplifying an equation?
Svar
0 = 0 means every allowed value is a solution; 0 = 5 means there is no solution.
Spjald 166
Spurning
What should you verify before comparing figures from different sources?
Svar
Common units and denominators. Convert first, then compare the same quantity on the same basis.
Spjald 167
Spurning
How do you interpret |x − a| < r when r is positive?
Svar
x is within r units of a: a − r < x < a + r.
Spjald 168
Spurning
What can a larger sample improve?
Svar
Precision, if the sampling method is sound. A huge biased sample can still give a confidently wrong picture of the population.
Spjald 169
Spurning
How should a cross-source recommendation be evaluated?
Svar
Apply the stated decision rule to the combined evidence. Do not substitute a personal preference for the rule.
Spjald 170
Spurning
If a worker finishes one job in t hours, what is the worker's hourly rate?
Svar
1/t of the job per hour.
Spjald 171
Spurning
What can an average hide?
Svar
The distribution. Two groups can share an average while differing sharply in range, concentration, or the number of extreme values.
Spjald 172
Spurning
What should you confirm before submitting a Multi-Source Reasoning answer?
Svar
That every required part is supported by the correct source and scope. One unsupported component can invalidate the whole decision.
Spjald 173
Spurning
How do you find the amount of a pure component in a mixture?
Svar
Concentration × total mixture amount. A 30% solution with volume 20 contains 0.30 × 20 = 6 units of the component.
Spjald 174
Spurning
What role does a concession usually play?
Svar
It acknowledges a point that weighs against the conclusion, then answers that point or limits its relevance. Don't mistake the conceded claim for the argument's main conclusion.
Spjald 175
Spurning
When can an apparent cross-source discrepancy be resolved?
Svar
When a stated difference in scope or method explains both figures. If no bridge is given, keep the conflict open.
Spjald 176
Spurning
What is the two-set overlap formula?
Svar
In A or B = in A + in B − in both. Subtract the overlap because it was counted twice.
Spjald 177
Spurning
What should you identify first in Table Analysis?
Svar
The row unit, column definitions, and any notes. This establishes what one record and each value represent.
Spjald 178
Spurning
What is the fundamental counting principle?
Svar
Multiply the choices at successive stages when each stage has a fixed number of available choices.
Spjald 179
Spurning
Why distinguish relative change from absolute change?
Svar
Relative change is the percentage change; absolute change is the amount added or lost. A 50% rise from 2 adds 1, while a 10% rise from 1,000 adds 100.
Spjald 180
Spurning
How should a table filter be translated?
Svar
Turn it into an exact inclusion rule. Apply every condition before counting or comparing rows.
Spjald 181
Spurning
For equally likely outcomes, what is the basic probability formula?
Svar
Favorable outcomes divided by total possible outcomes.
Spjald 182
Spurning
What makes a proposed causal mechanism useful?
Svar
It explains how the cause could produce the effect. A plausible, evidence-backed mechanism strengthens the causal link.
Spjald 183
Spurning
How do you find the median?
Svar
Order the values and take the middle value; for an even count, average the two middle values.
Spjald 184
Spurning
How should numeric values be sorted?
Svar
By numerical value, not digit order. For example, 12 comes after 9 in ascending order.
Spjald 185
Spurning
What is missed when evidence includes only successful cases?
Svar
The failures. Studying only surviving firms can make a strategy look safer or more effective than it is.
Spjald 186
Spurning
Two machines have stated constant rates of 1/3 and 1/5 job per hour and operate simultaneously without interference. May their rates be added?
Svar
Yes. The stated rates are constant and the machines do not interfere, so their combined rate is 1/3 + 1/5 = 8/15 job per hour.
Spjald 187
Spurning
How should a table ratio be built when filters are involved?
Svar
Derive the numerator and denominator separately from the question, then apply each filter only where it is relevant. Do not automatically filter both quantities or default to all rows.
Spjald 188
Spurning
What quantity is conserved when two solutions are mixed without loss?
Svar
The amount of the pure component. Set the sum of the starting component amounts equal to the final component amount.
Spjald 189
Spurning
When may table rows be added directly?
Svar
Only when they are disjoint parts of the same measure and use compatible units. Overlapping groups would be double-counted.
Spjald 190
Spurning
What does n! mean for a positive integer n?
Svar
The product of the positive integers from 1 through n.
Spjald 191
Spurning
Where is the argument's logical gap?
Svar
Between the evidence and the conclusion. State what must connect them without merely repeating either side.
Spjald 192
Spurning
How do you find the number in neither of two sets?
Svar
Subtract the number in the union from the total population.
Spjald 193
Spurning
How should rates from table groups be combined?
Svar
Divide the total numerator by the total denominator. Weight a group rate by its group size only when that size is the rate's denominator.
Spjald 194
Spurning
What is wrong with moving from some cases to all cases?
Svar
The conclusion is broader than the evidence. Evidence that some members have a trait doesn't show that every member does.
Spjald 195
Spurning
When should you use a permutation?
Svar
When selecting and arranging items and order matters. The number of ordered selections of r from n distinct items is n!/(n − r)!.
Spjald 196
Spurning
Why does table granularity matter?
Svar
A row-level fact may disappear or change after aggregation. Match the claim to the table’s level of detail.
Spjald 197
Spurning
How do you find the probability that an event does not occur?
Svar
1 − P(event). This is often the quickest route for “at least one” questions.
Spjald 198
Spurning
Why does a comparable control group help test causation?
Svar
It shows what happened without the suspected cause. If the groups differ mainly in that factor, the result is harder to explain another way.
Spjald 199
Spurning
How should missing table entries be treated?
Svar
As unknown unless the notes define another meaning. Exclude or include them only as the question directs.
Spjald 200
Spurning
What is the mode of a data set?
Svar
A mode is any value with the greatest frequency. Under the no-mode convention, there is no mode only when at least two distinct values all have equal frequency.
Spjald 201
Spurning
What makes a table comparison valid?
Svar
The values must have compatible measures, units, periods, populations, and definitions. Normalize only validly convertible differences; reject differences in population, period, or definition that cannot be reconciled.
Spjald 202
Spurning
What should you check when a prediction extends a past pattern?
Svar
Whether the conditions behind the past pattern will continue. A trend alone doesn't show that its causes will remain in place.
Spjald 203
Spurning
How should a drain or other undoing process enter a work-rate equation?
Svar
As a negative rate. Add productive rates and subtract rates that reverse the work.
Spjald 204
Spurning
How can you avoid losing your place while scanning a table?
Svar
Evaluate one condition at a time and mark qualifying rows mentally or on the scratchpad. Count only after the final filter.
Spjald 205
Spurning
Can evidence that an outcome is possible show it is likely?
Svar
No. Possibility only shows that an outcome can occur; probability requires evidence about how likely it is.
Spjald 206
Spurning
What correction is needed when counting the union of three sets?
Svar
Add the three individual counts, subtract all three pairwise overlaps, then add the triple overlap back once.
Spjald 207
Spurning
When does a filtered table support a decision?
Svar
When the qualifying rows satisfy the stated rule. Keep filtering, calculation, and decision as separate steps.
Spjald 208
Spurning
When should you use a combination?
Svar
When selecting items and order does not matter. The number of selections of r from n distinct items is n!/[r!(n − r)!].
Spjald 209
Spurning
What must support a recommendation?
Svar
A link from the proposed action to the stated goal. The argument also needs the action to be feasible and free of costs that defeat the goal.
Spjald 210
Spurning
How do AND and OR change a table filter?
Svar
AND requires every condition; OR requires at least one. Parenthesize mixed rules before scanning rows.
Spjald 211
Spurning
How do you find the probability that independent events both occur?
Svar
Multiply their probabilities: P(A and B) = P(A) × P(B).
Spjald 212
Spurning
What can make an alphabetical sort misleading?
Svar
Labels may contain categories or embedded numbers. Confirm whether the column is text, numeric, or chronological.
Spjald 213
Spurning
What kind of fact most directly strengthens an argument?
Svar
A fact that supports the missing link between evidence and conclusion. Merely repeating a premise adds little.
Spjald 214
Spurning
What is the range of a data set?
Svar
Maximum value minus minimum value.
Spjald 215
Spurning
What should you check at a filter cutoff?
Svar
Whether the boundary is inclusive. “At least 40” includes 40; “more than 40” does not.
Spjald 216
Spurning
A train covers 150 miles in 3 hours at a constant rate. What is its rate?
Svar
50 miles per hour. Rearrange distance = rate × time to get rate = 150 ÷ 3.
Spjald 217
Spurning
What is the most direct way to weaken an argument?
Svar
Undermine a necessary assumption connecting the evidence to the conclusion. The premises can remain true while the conclusion loses support.
Spjald 218
Spurning
What does a tie in the sorted column imply?
Svar
The tied rows share rank on that measure. Their display order does not create a performance difference.
Spjald 219
Spurning
How do you identify a useful evaluation question?
Svar
Test whether opposite answers would push the argument in opposite directions. If both answers leave the conclusion unchanged, the question isn't useful.
Spjald 220
Spurning
What should you identify first in Graphics Interpretation?
Svar
The chart type and what each visual encoding represents. Bars, lines, areas, and points support different readings.
Spjald 221
Spurning
How do repeated identical items affect arrangement counts?
Svar
For n total items, divide n! by the factorial of each repeated count. Identical items do not create new arrangements when swapped.
Spjald 222
Spurning
What should you read before estimating a plotted value?
Svar
Both axis labels, units, and category order. Position has meaning only after the axes are understood.
Spjald 223
Spurning
How do you test whether a statement is a necessary assumption?
Svar
Negate it. If that negation seriously damages the argument, the original statement was necessary.
Spjald 224
Spurning
How do you find the probability that one of two mutually exclusive events occurs?
Svar
Add their probabilities: P(A or B) = P(A) + P(B). Their overlap is zero.
Spjald 225
Spurning
What should you verify in a chart legend?
Svar
Which color, shape, or line maps to each series. Similar styling can otherwise swap the groups in your interpretation.
Spjald 226
Spurning
What does standard deviation measure?
Svar
How spread out values are around the mean. Greater dispersion means a larger standard deviation.
Spjald 227
Spurning
What standard should an inference meet?
Svar
It must follow from the given statements, without extra assumptions. Choose the modest claim the evidence guarantees.
Spjald 228
Spurning
What does a segment’s share depend on?
Svar
The correct whole. A category’s share of one region may differ from its share of the full dataset.
Spjald 229
Spurning
For motion along the same line, when do you add or subtract two speeds to get relative speed?
Svar
Add the speeds for opposite directions; subtract the smaller speed from the larger for the same direction.
Spjald 230
Spurning
What must a paradox explanation accomplish?
Svar
Make both surprising facts plausible at the same time. Rejecting either stated fact doesn't resolve the tension.
Spjald 231
Spurning
How is a segment in a stacked bar measured?
Svar
Subtract its lower boundary from its upper boundary. The upper endpoint alone is cumulative, not the segment value.
Spjald 232
Spurning
Eight students average 70 and twelve students average 80. What is the combined mean?
Svar
- The group sizes are the weights: (8 × 70 + 12 × 80) ÷ 20 = 76.
Spjald 233
Spurning
What is the difference between a graph’s level and its rate of change?
Svar
Level is the plotted value; rate of change is the slope. A high line can still be falling.
Spjald 234
Spurning
How should you describe a statement's role in an argument?
Svar
Describe what it does, not just what it says. It may support the conclusion, present an objection, answer that objection, or illustrate a principle.
Spjald 235
Spurning
What is P(A given B)?
Svar
P(A and B) / P(B), provided P(B) > 0. Restrict the sample space to outcomes in B.
Spjald 236
Spurning
How should slope be compared across a graph?
Svar
Use change in vertical value divided by change in horizontal value. Visual steepness is reliable only on the same scales.
Spjald 237
Spurning
A driver covers equal distances at 30 mph and 60 mph. Is the average speed 45 mph?
Svar
No. Using 60 miles for each leg gives 120 miles in 3 hours, so the average speed is 40 mph.
Spjald 238
Spurning
What should you identify first when evaluating a plan?
Svar
The plan's exact goal and success measure. A proposal can produce benefits yet still fail its stated objective.
Spjald 239
Spurning
What does a trend in a scatterplot establish?
Svar
An association in the displayed data. It does not by itself establish causation or predict every individual point.
Spjald 240
Spurning
How can you strengthen a causal explanation?
Svar
Rule out a credible alternative cause, support the proposed mechanism, or show the effect changes when the proposed cause changes.
Spjald 241
Spurning
How can an outlier affect a graphical trend?
Svar
It can pull a summary line or average away from the main cluster. Check whether the claim concerns all points or the typical pattern.
Spjald 242
Spurning
Why do probabilities usually change when sampling without replacement?
Svar
The sample space changes after each draw. Update both the favorable count and the total before multiplying conditional probabilities.
Spjald 243
Spurning
One value in an n-value set increases by d. How does the mean change?
Svar
It increases by d/n because the total rises by d while the count stays fixed.
Spjald 244
Spurning
When does a counterexample weaken a claim?
Svar
When the claim requires the counterexample not to exist. One genuine exception can defeat an absolute claim, but may barely affect a modest one.
Spjald 245
Spurning
What is the parity of the sum of two odd integers?
Svar
Even. Each odd integer is one more than an even integer, so the two extra ones add to 2.
Spjald 246
Spurning
What can an aggregate graph hide?
Svar
Differences among subgroups or periods. A stable total can coexist with large offsetting changes inside it.
Spjald 247
Spurning
When is interpolation reasonable on a graph?
Svar
When the graph implies continuity between nearby points. Do not interpolate across separate categories.
Spjald 248
Spurning
What makes information relevant to evaluating an argument?
Svar
It bears on the uncertain link the conclusion depends on. Interesting facts about the topic may still be logically irrelevant.
Spjald 249
Spurning
How precise should a value read from a graph be?
Svar
Only as precise as the scale supports. Use a defensible interval when the mark falls between ticks.
Spjald 250
Spurning
Must a necessary assumption prove the conclusion?
Svar
No. It only has to be required for the argument to work; it need not be enough to establish the conclusion on its own.
Spjald 251
Spurning
How do you multiply positive numbers written in scientific notation?
Svar
Multiply the coefficients, add the powers of 10, then adjust the coefficient to be at least 1 and less than 10.
Spjald 252
Spurning
How should a graph-based decision be made?
Svar
Translate the visual into values or bounds, then apply the stated rule. Do not decide from appearance alone.
Spjald 253
Spurning
When is backsolving from answer choices especially useful?
Svar
When the choices are concrete values and direct algebra is slower than testing them in the original conditions.
Spjald 254
Spurning
How can axis scale distort a visual impression?
Svar
Unequal intervals or a truncated baseline can magnify or compress differences. Use tick values, not apparent distance alone.
Spjald 255
Spurning
When should you combine two statements for an inference?
Svar
When they share a term or relationship that creates a guaranteed consequence. Don't combine them through an unstated causal or statistical link.
Spjald 256
Spurning
When is a product of integers odd?
Svar
Only when every factor is odd. One even factor makes the entire product even.
Spjald 257
Spurning
What often resolves two apparently conflicting results?
Svar
A hidden difference in group, time, measurement, or conditions. The results may describe different slices of the situation.
Spjald 258
Spurning
How should equal distances on a logarithmic axis be interpreted?
Svar
As equal multiplicative changes, not equal absolute changes. Read the labeled values before comparing gaps.
Spjald 259
Spurning
Why start with a middle answer choice when backsolving ordered options?
Svar
Its result often eliminates half the choices at once when the relationship is monotonic.
Spjald 260
Spurning
What makes a Two-Part Analysis response complete?
Svar
Both selections must satisfy their own column prompts under the same stem. Treat the pair as one submitted response.
Spjald 261
Spurning
What is an analogy doing when it supports a claim?
Svar
It argues that because two cases share relevant features, a result or principle from one likely applies to the other.
Spjald 262
Spurning
How do you represent three consecutive odd integers?
Svar
n, n + 2, and n + 4, where n is an odd integer.
Spjald 263
Spurning
What should you identify before solving Two-Part Analysis?
Svar
The role of each column. One may ask for a condition while the other asks for a consequence or decision.
Spjald 264
Spurning
What values should you test first in a claim about an unspecified number?
Svar
Test allowed categories that may behave differently: positive, negative, zero, fractional, and boundary values.
Spjald 265
Spurning
How can an unchanged bottleneck defeat a plan?
Svar
Improving a nonlimiting step won't improve the final outcome if another constraint still controls it. Faster ordering doesn't help when production is already full.
Spjald 266
Spurning
How does the shared stem affect the two parts?
Svar
Its definitions and constraints apply to both. Keep them fixed while testing each column’s requirement.
Spjald 267
Spurning
How do you count the positive divisors of an integer greater than 1 from its prime factorization?
Svar
Add 1 to each prime exponent, then multiply those results.
Spjald 268
Spurning
In Two-Part Analysis, must the two selected entries be the same?
Svar
In the current format, the two selected entries may be the same or different. A linkage in the stem determines whether you must reason through them jointly, not whether their values match.
Spjald 269
Spurning
What makes evidence for a general claim strong?
Svar
It should be relevant and reliable and, if case-based, come from representative cases. More evidence isn't automatically better evidence.
Spjald 270
Spurning
How do you factor a difference of squares?
Svar
Use x² − y² = (x − y)(x + y).
Spjald 271
Spurning
When should the two Two-Part Analysis selections be solved together?
Svar
When one shared relationship constrains both. Test candidate pairs against that relationship instead of solving isolated fragments.
Spjald 272
Spurning
How can one counterexample evaluate a universal claim?
Svar
One valid counterexample disproves a claim that is supposed to hold for every allowed value.
Spjald 273
Spurning
How does an alternative explanation weaken a conclusion?
Svar
It shows that the evidence can be true without the proposed explanation being true. The alternative must account for the same result.
Spjald 274
Spurning
In Two-Part Analysis, how can one column help solve the other?
Svar
A valid selection can narrow the remaining candidates when the parts share a constraint. Recheck the final pair in both columns.
Spjald 275
Spurning
How do you test whether x² + bx + c factors into integer binomials?
Svar
Look for integers r and s with r + s = b and rs = c. If they exist, the factorization is (x + r)(x + s).
Spjald 276
Spurning
Which unknown should you evaluate first in a plan argument?
Svar
A condition that could make the plan achieve or miss its goal. Focus on feasibility, response, costs, and side effects tied to that goal.
Spjald 277
Spurning
How should a trade-off between two measures be evaluated?
Svar
Apply the stated priorities or limits. An option is better only relative to the rule, not because one measure is largest.
Spjald 278
Spurning
How can estimation screen answer choices before exact calculation?
Svar
Approximate the expression's magnitude, then eliminate choices that are far too large or too small.
Spjald 279
Spurning
In a constrained-decision Two-Part Analysis problem, what should you check before comparing candidates?
Svar
Check every hard constraint first. Discard any option that breaks a required limit, then compare only the feasible candidates.
Spjald 280
Spurning
What does a defensive assumption do?
Svar
It rules out a threat that would break the argument. For example, a revenue plan may assume that its added costs won't exceed the new revenue.
Spjald 281
Spurning
What restriction applies when a variable appears in a denominator?
Svar
Exclude every value that makes the denominator zero.
Spjald 282
Spurning
How does an objective differ from a constraint?
Svar
A constraint determines what is allowed; an objective ranks the allowed options. Apply them in that order.
Spjald 283
Spurning
Which quick checks catch many Quant answer errors?
Svar
Check the sign, units, allowed range, and rough size against the question's conditions.
Spjald 284
Spurning
What inference is safe from a statement about most members?
Svar
More than half have the stated trait. You can't infer that all do, that any particular member does, or that most have another trait.
Spjald 285
Spurning
How should a two-part threshold rule be handled?
Svar
Translate each threshold with the correct inequality, including its boundary. Then test both selected values against it.
Spjald 286
Spurning
Where can one negative sign appear in a fraction without changing its value?
Svar
Before the fraction, in the numerator, or in the denominator: −(a/b) = (−a)/b = a/(−b), provided b ≠ 0.
Spjald 287
Spurning
How does an argument choose between competing explanations?
Svar
It presents evidence that one explanation handles better than the others, often by ruling out a rival prediction.
Spjald 288
Spurning
What is an efficient way to handle two linked algebraic targets?
Svar
Express both in terms of one variable or invariant. Evaluate candidate values only after the relationship is clear.
Spjald 289
Spurning
How do you solve x² = c over the real numbers?
Svar
If c > 0, x = ±√c; if c = 0, x = 0; if c < 0, there is no real solution.
Spjald 290
Spurning
What should you check when two selected quantities form a ratio?
Svar
Order and scale. The ratio A:B is not interchangeable with B:A, and proportional pairs may all fit.
Spjald 291
Spurning
How does a positive proper fraction compare with 1?
Svar
It is less than 1 because its numerator is smaller than its denominator.
Spjald 292
Spurning
Which side effects matter when evaluating a plan?
Svar
Effects that change the plan's net result or work against its goal. A small unrelated inconvenience usually doesn't matter.
Spjald 293
Spurning
How should a two-part logical claim be tested?
