You are the designer/evaluator of a student survey for a college that examines student behaviors in a variety of key areas. One area of focus is potential gender differences in student study habits, and the survey asks each respondent how often he/she studies all night (never, sometimes, frequently or very frequently). After receiving the results, you run the following Exhibit 6 in Stata:
