Chapter 7 Test
Chapter 7 - Day 12
Questions to be Sure to Include
Make sure that one of the questions requires students to do inferential thinking. This will require them to first do a probability calculation and then to answer the question “Do we have convincing evidence of ________”.
A question where students are asked to calculate a probability of getting a certain value for one individual from the population, then also asked to calculate the probability of getting a certain mean for a sample of individuals. Students should interpret their answer for each.
Don’t be afraid to ask a Chapter 6 binomial question on this test if it fits.
It is not necessary to have students create a sampling distribution with all possible samples from a very small population (like in the activity from Section 7.1). This task works well for introducing the concept of a sampling distribution, but is not necessary to assess.
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.
There are a lot of formulas in this Chapter. Don’t memorize them. Understand them. Know how the formulas for a binomial distribution relate to the formulas for the sampling distribution of a sample proportion.
Know everything on the Chapter 7 Review sheet. This will also help you for the rest of the course.
Be able to read a question and quickly identify whether the question is referring to the population distribution or the sampling distribution. If the question requires a sampling distribution, is it for a sample proportion or for a sample mean?
