What does Two-variable Data Models And Scatterplots test on the SAT?

These questions analyze relationships between two variables using scatterplots, lines of best fit, residuals, and model predictions. Association does not by itself establish causation.

Common question types

Interpret slope or intercept in a fitted model
Estimate a value from a line of best fit
Compare model fit using residuals or scatter

Common traps

Extrapolating far beyond the observed data
Interpreting correlation as causation
Using a data point instead of the model's predicted value

How do I improve at Two-variable Data Models And Scatterplots?

1Identify the explanatory and response variables with units.
2Describe direction, form, and strength before using a model.
3Distinguish observed values from predictions and residuals.

Desmos method

Enter the data in a table and fit y_1 ~ mx_1 + b or the requested nonlinear model. Use the fitted parameters for predictions and inspect residual size before trusting the model.
