Question

Quizplus · Accepted Answer

The independent variable is the variable that is manipulated in the study, in this case whether or not the nursing home residents received a pet. A is incorrect because the number of months of testing is a dependent variable that is measured, not manipulated. C and D are also incorrect because they are outcome measures, not independent variables.
