ByStatistics 300: Elementary Statistics. Section 11-2. Chapter 11 concerns the analysis of statistics that are “counts” in “categories”. Section 11-2 concerns “counts” in “categories” where each data value falls in one and only one category. . Chapter 11-2. Two names; same procedure

ByChapter 26. Comparing Counts . Goodness-of-Fit. A test of whether the distribution of counts in one categorical variable matches the distribution predicted by a model is called a goodness-of-fit test.

ByInference for Categorical Data. William P. Wattles, Ph. D. Francis Marion University. Continuous vs. Categorical. Continuous (measurement) variables have many values Categorical variables have only certain values representing different categories

Byc 2 test for independence. Used with categorical, bivariate data from ONE sample Used to see if the two categorical variables are associated (dependent) or not associated ( independent ). Assumptions & formula remain the same!. Hypotheses – written in words.
