Two variable data SAT practice questions
Math, Problem Solving and Data Analysis. 68 questions
Scatterplots, lines of best fit and linear or exponential models of real data.
What this skill tests
- Reading a scatterplot
- Line of best fit: slope and predictions
- Choosing a linear or exponential model
How to approach it
- 1Interpret the slope of a best fit line as the predicted change per unit.
- 2Predictions come from the model, not from individual data points.
- 3Constant differences mean linear; constant ratios mean exponential.
