What does Crosstabulation summarize?

Crosstabulation is a statistical tool that provides a means to summarize the relationship between two categorical variables by presenting the data in a tabular format. This two-way table displays the frequency counts of the classes or categories of the variables, making it easier to observe patterns, trends, and correlations between the variables. By organizing the data in this manner, one can assess how the two variables interact with one another and draw insights that might not be apparent when looking at one variable in isolation.

In this context, option B accurately captures the essence of crosstabulation as it highlights the focus on two variables and organizes their classes in a format that allows for easy comparison and analysis. Understanding crosstabulation is vital in analyzing survey data or any dataset where relationships between categorical variables are of interest.
