Lesson Plans for CED Unit 6: Inference for Proportions

Updated: Feb 15


All right, it's time to start the most important topic in statistics: Inference (confidence intervals and significance tests). This is what we've been working towards all year!


Let's take a moment and recap where students have been before this. Before starting this unit, students should have an understanding of Unit 5: Sampling Distributions for both one and two samples. They have learned about the sampling distributions for both proportions and for means.


In CED Unit 6, we will be using their knowledge of the sampling distributions for proportions and extending it into inference.

This unit covers inference for proportions ONLY (no means). Inference for means will come next in CED Unit 7. If you're a new teacher, make sure to double check the sequence in your text against the CED. In an earlier blog post, we explained what the newly proposed instructional sequence in the College Board AP Statistics Course and Exam Description (CED) entails.


If you are using TPS 4e, 5e, or Classic 6e and are not planning on following the sequence in the CED, you can simply use the sequence in our 150 Days of AP Stats. This sequence will cover everything in the CED (just in a slightly different sequence).

If you are using TPS 6e UPDATE or want to use the new sequence of topics in the CED, here is your plan:
