Guide to Sullivan’s Chapter 12

Big picture: Now we turn to inferences about categorical data. Once again, our HT asks, Could chance account for the sample we got, or is it too far from H₀? This chapter covers Case 6 (one population, one categorical varieable) and Case 7 (one population with two attribute variables, or two or more populations with one attribute variable).

Handout: The handout Chi-Squared Tests replaces Chapter 12 of the textbook.
