Data Insights: Multi-Source Reasoning Flashcards

An MSR set includes a chart (Tab 1), a memo (Tab 2), and a data table (Tab 3). A question requires data from the chart and the table only. The memo is:

Answer: A potential distractor for this question

Not every tab is needed for every question; unused sources often serve as distractors.

A memo says 'Region A sales must be at least 15% higher than Region B to expand.' Tab 2 shows A=$230k, B=$200k. Should they expand?

Answer: Yes, A is exactly 15% higher, meeting the 'at least 15%' threshold

230k is exactly 15% above 200k, which satisfies the 'at least 15%' requirement.

In MSR, a 'two-part analysis' style question may ask you to select one option per column. The two columns are:

Answer: Often interdependent conditions you evaluate together

Two-part items typically require finding values or conditions that jointly satisfy the constraints.

A table lists monthly revenue; a question asks for the quarter-over-quarter growth. You should:

Answer: Sum each quarter's months, then compute the percentage change

Quarterly figures require aggregating the relevant months before computing growth.

An MSR source contradicts a figure stated in the question stem. The reliable basis for answering is:

Answer: The provided source data unless the stem defines a new scenario

Source tabs are authoritative unless the question explicitly introduces a hypothetical that overrides them.

Why does MSR emphasize reading comprehension as much as quantitative skill?

Answer: Because conditions and rules are often embedded in prose that must be applied to numbers

MSR blends verbal rules with quantitative data, requiring careful reading to apply constraints correctly.

A question asks which of three suppliers meets all criteria listed across two tabs. The best method is:

Answer: Check each supplier against every criterion, eliminating those that fail one

Systematic elimination against all criteria ensures only fully-qualifying options remain.
