Concept Snapshot

Definition
A variant of Command of Evidence: the evidence is a table, bar graph, or line graph instead of a quotation.
What the SAT tests
Completing a sentence about data, or choosing the data that supports a researcher's conclusion.
Key rule
Read the claim FIRST, then go to the graphic for exactly the cells or bars it needs — titles, units, and axis labels included.
Most common mistake
Answering from the graphic's overall trend when the claim asks about one specific category or year.
Prerequisite
Command of Evidence — Textual

Visual Explanation

Bee species counted, by habitat
Meadow
61
Urban garden
52
Forest
48
Farmland
23
Data questions are read in a fixed order: title → axes/labels → units → THEN the values the claim needs. Here the claim compares farmland against everything else. Pull exactly the cells the sentence asks for, nothing more.

Info & Ideas

How the SAT Tests It

Pattern

Complete the Claim

A sentence about the data has a blank; pick the option the graphic actually shows.

Clue: "Which choice most effectively uses data…"
Pattern

Support the Conclusion

A researcher's conclusion must be backed by the right comparison from the table.

Clue: "…to support the researchers' conclusion"
Pattern

True but Irrelevant

Distractors state accurate data that doesn't address the claim.

Clue: Accurate numbers, wrong comparison

Worked Example

A table shows bee species counts in four habitats: forest (48), meadow (61), urban garden (52), farmland (23). Claim: "managed agricultural land supports notably fewer bee species than less intensively managed habitats." Which data completes it?

The claim compares farmland against the other three habitats. We need data making that specific comparison.
Complete-the-claim: the numbers must match the table AND fit the sentence's logic.
Farmland = 23. The others range 48–61. The gap (25+ species) is the claim's "notably fewer."
"Meadows had the most species (61)" is TRUE but irrelevant — the claim is about farmland vs. the rest, not which habitat wins.

Try It Yourself

A graph shows average commute times: 2010 = 25 min, 2015 = 26 min, 2020 = 27 min, 2023 = 31 min. Claim: "commute times, after rising only gradually for a decade, increased sharply in the early 2020s." Which choice best supports this?

Common Traps

What students do

Verifying the numbers but not the logic.

Why it fails

Most distractors are factually accurate readings of the graphic — accuracy alone can't be the filter.

Do this instead

Check two boxes: (1) matches the graphic, (2) completes THIS claim's comparison. Both or eliminate.
