Chapter 8: Inference for Categorical Data

This set of labs discusses methods of inference for numerical data, starting with tests for a single population proportion and extending to inference for two or more groups in the two-way table setting. The second lab also introduces odds ratios and their use for summarizing data collected via outcome-dependent sampling.
