The following video illustrates inference in Case CC where we are investigating the association between two categorical variables using two-way tables (contingency tables). In SPSS we will use CROSSTABS. We illustrate adding row percentages to the default table output and go through how to select the Chi-square test and Fisher’s Exact test. The following files are associated with this video.
