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 r2.
-
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.
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.
