AP Stats Chapter 2 Test
Chapter 2 - Day 9
Start Here
Questions to Be Sure to Include
-
MC question that require students to use the 68-95-99.7 rule.
-
MC question that asks students to find the median and IQR from a cumulative relative frequency graph.
-
MC question where a z-score 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 z-score.
-
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 68-95-99.7 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.
