What the SAT Actually Tests

Scatterplot questions give you plotted data with (usually) a line of best fit and ask you to interpret its slope or intercept in context, predict a value, compute the difference between an actual data point and the line's prediction, or judge whether a linear or exponential model fits the association.

The line of best fit is a prediction machine: for a given x, the line's height is the predicted y, and (actual − predicted) is the residual questions love to ask about. Slope-in-context follows the standard recipe — predicted change in y per one unit of x. Count carefully on the axes; most errors here are reading errors, not concept errors.

Original Scatterplots & Two-Variable Data Practice Questions

These fixed public samples come from Grind1600's original question bank. Choose an answer and check your reasoning before reading the explanation.

Question 1easy
A researcher collected data on the number of hours of sunlight and the height of plants. Which type of graph would be most appropriate to display the relationship between these two variables?
Question 2easy
A librarian begins a shift with a large cart of books that need to be reshelved. The librarian works at a constant rate throughout the afternoon. What type of model is best to model the number of books remaining on the cart at any given time throughout the afternoon?

Traps to Avoid

  • Answering with the actual data point's value when the question asks what the line of best fit predicts (or vice versa).
  • Misreading axis scales that count by 5s, 20s, or 0.5s rather than 1s.
  • Calling an association exponential just because it rises quickly — a straight-line pattern is linear regardless of steepness.

More Problem-Solving & Data Analysis Skills

Ratios, Rates & Units

Setting up proportions, converting units, and reasoning with rates — the most common word-problem machinery on the SAT Math section.

Percentages

Percent change, percent of a quantity, reverse-percentage problems, and multi-step percent scenarios like tax-plus-discount.

Data Distributions & Measures of Center

Mean, median, mode, range, and standard deviation — and how outliers or skew change them — read from lists, tables, and frequency plots.

Probability

One-event and conditional probability, usually read out of two-way frequency tables — the key is identifying the correct restricted group.

Inference & Margin of Error

What sample results let you conclude about a population, how margin of error works, and why sample size changes confidence.

Evaluating Statistical Claims

Judging what a study design supports: random sampling vs. random assignment, causation vs. correlation, and generalizability.
