Question

List the independent and dependent variables for each research experiment below:

a. Who has more team spirit: college football fans or college basketball fans? To find out, we visit ten colleges that have both football and basketball teams. We go to games and count how many people are wearing team colors or logos. The variables are sport (football or basketball) and percent wearing school colors/logos.

b. A legislator in DC says that teachers need to be paid on a sliding scale that is dependent on student scores in the classroom. For the claim, we look at standardized test data, end of year, for groups of students per teacher. Then we compare scores from the previous year to the end of this year. Teacher-assigned grades are an independent variable. Name the other variables and list them as independent or dependent.
