- AP Free Response Questions that you can use on the Chapter 3 Test

#### Questions to be sure to include

- A question that includes computer output, so that students have to identify the equation of the LSRL from the computer output.
- A question that requires students to think about correlation versus causation.
- A question that asks students to think about how an outlier affects the LSRL.
- A question where students have to interpret r
^{2}. - A free response question which asks students to describe the relationship (DUFS!).
- A free response question where students have to interpret the slope of the LSRL.
- A free response question where students have to calculate and interpret a residual.
- A free response question which asks students to provide more than one reason why a line is an appropriate model for a set of data.
- At least one old AP question. There are many to choose from and they are very accessible for students after completing this chapter.

#### Here are some tips to give your students

- Close reading and careful writing are critical to your success this year.
- Be sure to answer all parts of each question.
- Know how to describe the relationship between two quantitative variables (DUFS!)
- Know the many justifications you can use to argue that a data set can be modeled as a linear relationship.
- Know how to interpret values (slope, y-intercept, residual, standard deviation of the residuals).

#### Quick tip for writing the test

Create an easy to understand context with some two-variable data and then you can ask several of your questions within that one context. A good rule is one context for each page of the free response questions on your test.
