Checking if two categorical variables are independent can be done with Chi-Squared test of independence. Since the valid values run through 5, we'll RECODE them into 6. We can calculate these marginal probabilities using either Minitab or SPSS: To calculate these marginal probabilities using Minitab: This should result in the following two-way table with column percents: Although you do not need the counts, having those visible aids in the understanding of how the conditional probabilities of smoking behavior within gender are calculated. If you'd like to download the sample dataset to work through the examples, choose one of the files below: To describe a single categorical variable, we use frequency tables.
