A troop leader recorded whether the members of two troops prefer hiking or swimming. The troop leader plans to create a two-way table to display the results. Which variables can the troop leader use as the row and column headings of the table?

A two-way table organizes data by two categorical variables. Here, the categories are troop number (the two troops) and activity preference (hiking or swimming), so these can be the row and column headings. The other choices include counts, such as the number who prefer an activity, rather than a second categorical variable.
