Best Evidence Selection with Data
How to Let the Numbers Speak on the SAT
Track the author’s logic, locate evidence quickly, and sharpen your reasoning.
Evidence-First Reading
Anchor every answer in the exact line that proves it. If you cannot point to the words, it is not the answer.
- Read the question, then scan for the line that directly supports a choice.
- Match wording, not vibe: synonyms are fine, new ideas are not.
- If two answers feel close, eliminate the one with any extra claim.
Why Best Evidence Selection with Data Matters on the SAT
Questions where the answer is literally written in a chart or table are among the most reliable sources of points on the SAT Reading and Writing section. These are not opinion questions, and they are not asking you to interpret the author's mood. They present hard data, a number, a trend, or a comparison, and test whether that data supports a given claim. Once you learn to read data with precision, these questions become some of the most predictable on the entire test.
The skill we're building today is called Best Evidence Selection (Quantitative). It asks you to look at a passage that makes a claim, then examine an accompanying figure, a table, bar chart, line graph, or scatterplot, and decide which answer choice is genuinely supported by the data. It sounds straightforward, and it is, once you know what to watch for. The SAT counts on students rushing, misreading axes, or confusing correlation with specific values. You're going to learn to slow down just enough to avoid every one of those traps.
What Is This Skill?
Best Evidence Selection (Quantitative) is the ability to identify which piece of numerical or graphical data most directly supports, weakens, or illustrates a specific claim made in a passage. Unlike purely text-based evidence questions, where you're scanning for a quote that backs up an interpretation, quantitative evidence questions ask you to read a figure and connect what it shows to what the passage says.
Think of it this way: a passage might claim that "participation in after-school programs declined sharply after 2018." A table next to that passage shows enrollment figures for 2016 through 2022. Your job is to find the data point or trend in that table that either confirms or complicates that claim. The right answer won't require you to calculate anything complex, it will require you to read carefully and match precisely.
This skill sits at an advanced cognitive level because it demands that you hold two kinds of information in your mind simultaneously: the verbal claim from the passage and the numerical reality from the figure. You need to translate between words and numbers fluently. That's a higher-order move, and it's exactly the kind of reasoning the SAT rewards.
How the SAT Tests This Skill
On the digital SAT, you'll encounter short passages paired with a data display, a table, chart, or graph. The question will typically ask something like:
- "Which finding from the study, if true, would most directly support the researcher's hypothesis?"
- "Which choice most effectively uses data from the table to support the claim in the text?"
- "Which choice best illustrates the trend described in the text?"
Notice the pattern: every question is asking you to bridge a passage claim to a data point. The SAT is not asking you to interpret the data freely or draw your own conclusions. It's asking you to find the match, the specific number, comparison, or trend that lines up with a specific statement.
The wrong answers are carefully designed. They often reference real data from the figure, so they look credible, but they support a different claim, describe the wrong variable, or reverse a comparison. The test is checking whether you can resist the pull of an answer that sounds "data-ish" and instead lock onto the one that actually corresponds to the claim at hand.
Common Data Traps
- Wrong claim: The data is real, but it supports a different statement than the one in the passage.
- Wrong variable: The answer cites the correct table but points to the wrong row, column, or condition.
- Reversed comparison: The choice flips which group is higher, lower, or faster.
A Reliable Strategy for Best Evidence Selection with Data
Here's a four-step approach you can rely on every time you face one of these questions. Internalize this process and it will become automatic.
- Identify the Claim First
Before you even glance at the figure, read the passage and underline the specific claim the question is asking about. What exactly is being asserted? Is it that something increased? That one group outperformed another? That a variable had no effect? Get the claim crystal clear in your mind. If you can't state it in one sentence, reread the passage.
- Orient Yourself to the Figure
Now look at the data display. Before reading any values, ask yourself three quick questions: What do the axes or column headers represent? What are the units? What time period or categories are shown? This takes five seconds and prevents the most common misreads. Students who skip this step often confuse which variable is which, and the SAT is counting on that confusion.
- Find the Relevant Data
Go back to the claim from Step 1. Now scan the figure for only the data that relates to that claim. If the claim is about a comparison between two groups, find those two groups' values. If it's about a trend over time, trace the line or compare the columns across the relevant years. Ignore everything else in the figure, it's there to distract you.
- Match, Don't Infer
Finally, go to the answer choices. The right answer will directly correspond to what you found in Step 3. It won't require a leap of logic or an assumption. If you find yourself thinking "well, this could mean..." you're probably drifting toward a wrong answer. The correct choice will feel almost boringly literal. That's how you know it's right.
A helpful self-check: after selecting your answer, ask yourself, "Could someone verify this by looking at the figure alone?" If the answer is yes, you're in good shape. If the answer requires outside knowledge or speculation, reconsider.

Key Takeaways for Best Evidence Selection with Data
- Identify the claim before touching the data. The single most important habit is knowing exactly what you're trying to support before you look at a single number. This prevents you from getting pulled toward interesting-but-irrelevant data points.
- Orient yourself to the figure. Five seconds spent reading axis labels, column headers, and units will save you from the most common trap answers on the SAT. Never assume you know what a chart shows, verify it.
- Match, don't infer. The right answer will feel direct and almost obvious once you've located the relevant data. If you're making assumptions or drawing conclusions beyond what the numbers literally show, you've gone too far.
- Watch for partial matches. The SAT loves answer choices that use real data from the figure but apply it to the wrong claim. Always check that the data in your chosen answer supports this specific claim, not just any claim.
- Two-part claims need two-part evidence. When a passage makes a complex argument with multiple components, the best evidence will address all parts. An answer that only covers half the claim is only half right, which on the SAT means fully wrong.
Conclusion: The Core Rule for Best Evidence Selection with Data
Quantitative evidence questions can feel intimidating at first, there's a passage and a figure, and the answer choices are dense with numbers. But here's what makes this skill so rewarding to develop: the answer is always in the data. You're not guessing what an author might have meant. You're not debating nuances of tone. You're reading numbers and matching them to claims. That's it.
The four-step strategy you practiced here, identify the claim, orient to the figure, find the relevant data, and match directly, works every single time because these questions are built on a predictable structure. The SAT can vary the subject matter from marine biology to literary history to trade economics, but the underlying logic is always the same: does this data actually support this statement?
As you continue preparing, pay attention to charts and graphs you encounter outside of test prep, in news articles, textbooks, even social media infographics. Ask yourself what claims they're being used to support, and whether the data genuinely backs those claims up. You'll find that this skill doesn't just help on the SAT. It makes you a sharper, more critical thinker in every context where someone uses numbers to make a point. And that's a skill worth far more than any test score.
