Optional Supplements
You can access an excellent free online textbook on OpenIntro Statistics here, co-authored by Duke faculty. You can pay a suggested but adjustable price for a tablet-friendly pdf, but you can also just get the regular pdf for free. For Module 5, the following optional readings may be particularly helpful supplements:
- Chapter 5.2 Confidence intervals for a proportion. This provides introductory material on confidence intervals elaborating on 5.A.1.
- Chapter 5.3 Hypothesis testing for a proportion. This elaborates on the introduction to hypothesis testing from 5.B.1.
- Chapters 7.1, 7.3, and 7.5 cover material from 5.B.2 on using t-tests for a single mean, the difference of two means, and many pairwise means respectively.
- Chapter 6.3 discusses the chi-square test for categorical data introduced in 5.B.2.
In addition, here is the documentation for the scipy.stats library that implements most of the functionality described here as well as many other useful statistical functions.
