AP Stats Chapter 2 Test
Day 18
Start Here
Questions to Be Sure to Include

MC question that require students to use the 689599.7 rule.

MC question that asks students to find the median and IQR from a cumulative relative frequency graph.

MC question where a zscore is given and students have to work backwards to figure out an unknown mean or unknown standard deviation.

MC question that asks students to interpret a zscore.

Highest Priority: FR question that ask students to do normal distribution calculations.

Area to the left

Area to the right

Find a value for a given area

FR question that has a context that includes transformations of data (add/subtract and multiply/divide) and asks about center and variability. You could also review Chapter 1 in this question by asking them to describe the distribution of the original data.

FR question that asks students to identify the shape of a distribution of data based on the cumulative relative frequency graph.

A question for assessing Normality is not high priority.
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.

Normal distribution calculations are the single most important idea in Chapter 2. Remind students that they need to draw and label a picture, show a formula and numbers, and be able to interpret the final answer.

Know what happens to shape, center, and variability when data is transformed.
Activity: Normal Curve Calculations
A question that is assessing Normality can be very lengthy if they are checking using the 689599.7 rule. We don’t believe this to be a high priority. We think it is a worthwhile activity in class, but not necessary for the test.
