More One-Sample Tests

In this chapter, we will present other one-sample procedures for addressing concerns related to variability, relationships, and categorical variables. Within the context of the test for variance, we will also consider tests of shape, with respect to departures from normality. Specifically with categorical variables, we will address the issue of shape with what is called a “chi-squared (χ2) goodness-of-fit test;” the basic idea of which is whether the numbers of observations (counts) within the categories depart from some expected counts for the corresponding categories.
