Today we practiced Free Response Questions (FRQs). Joshua seems reluctant to work on these questions, but they are very important for his AP exam.

College Board Website, AP Statistics, Unit 6.3: How to interpret a confidence interval for a population proportion and use the interval to justify a claim; how to interpret a confidence level and explain the factors that affect the margin of error; review of the process of constructing and interpreting a confidence interval for a population proportion.

College Board Website, AP Statistics, Unit 6.2: How to identify the procedure and check the conditions for constructing a confidence interval for a population proportion; how to calculate the confidence interval; and how to determine the sample size that will result in a given margin of error.

College Board Website, AP Statistics, Unit 6.1: The logic of significance testing for a sample proportion.

Joshua has not completed the Free Response Question (FRQ) section of the Unit 5 test that I assigned as homework. He needs practice with FRQs because they constitute an important part of the AP exam.

Joshua took Part B of the Unit 5 test, and placed in the College Board's "light brown". He also partially completed Part C of the test.

Today, Joshua took Part A of the Unit 5 test. He scored 12/15, which placed him in the College Board's "dark green". The scale ranges from dark brown (poor) to dark green (good).

We did another practice FRQ and then reviewed Unit 5.8, which dealt with sampling distributions of differences.

We completed our practice of an FRQ and then reviewed Unit 5.7, which covered the shape, center, and variability of the sampling distribution of the sample mean.

We reviewed Unit 5.6 dealing with sampling distributions of differences in proportions, and we began to work on a Free Response Question (FRQ) on the subject.

Today we completed our review of Unit 5.5.
