What this tests

What to know for this SAT skill

Practice examples

Try a few SAT-style questions

Example 1 Easy

In a scatterplot, y generally increases as x increases. What type of association is shown?

  1. Positive
  2. Negative
  3. No association
  4. Impossible to tell
Show answer and explanation

Answer: Positive

When both variables tend to increase together, the association is positive.

Example 2 Medium

A line of best fit predicts y = 42 when x = 6. What does this prediction mean?

  1. The actual value must be exactly 42.
  2. The model estimates y to be about 42 when x is 6.
  3. The x-value must be 42.
  4. There is no relationship between x and y.
Show answer and explanation

Answer: The model estimates y to be about 42 when x is 6.

A line of best fit gives an estimate, not a guaranteed exact value.

Example 3 Hard

Most points follow an upward trend, but one point is far below the pattern. What is that point called?

  1. Intercept
  2. Outlier
  3. Slope
  4. Median
Show answer and explanation

Answer: Outlier

A point far from the overall pattern is an outlier.

Quick drills

Practice this skill from more angles

Drill 1

Identify positive, negative, or no association

Pause before the answer choices, write the rule or setup you need, then check whether the question is asking for the value, the relationship, or the best-supported conclusion.

Drill 2

Interpret a line of best fit

Pause before the answer choices, write the rule or setup you need, then check whether the question is asking for the value, the relationship, or the best-supported conclusion.

Drill 3

Recognize outliers in a scatterplot

Pause before the answer choices, write the rule or setup you need, then check whether the question is asking for the value, the relationship, or the best-supported conclusion.

Drill 4

Use data trends to make reasonable predictions

Pause before the answer choices, write the rule or setup you need, then check whether the question is asking for the value, the relationship, or the best-supported conclusion.

Avoid these traps

Common mistakes on this skill

Solving before naming the task

The SAT often hides the real skill inside familiar wording. Identify the rule, relationship, or question type first.

Choosing an answer that only partly fits

Many wrong answers are close. Check every condition in the question before committing.

Skipping the final check

Reread what the question asks for so you do not answer a nearby but different question.
