Quizplus · Accepted Answer

The variable measuring participation in athletics is a quasi-independent variable because the researcher did not manipulate or randomly assign athletic participation to the participants; instead, they observed and compared the groups based on whether or not they were already athletes. The dependent variable in this study is GPA, as it is the variable being measured and compared between the two groups. The variable measuring participation in athletics is not an interval scale, as it is not a numerical variable with equal intervals between values.
