Question

Quizplus · Accepted Answer

An independent variable refers to the variable that is manipulated or changed by the researcher in an experiment. In this case, Dr. Van Offer is studying a new communication method, which he would use as the independent variable in a randomized study to determine its effects on the outcome. The dependent variable, on the other hand, is the variable that is measured or observed to determine the effects of the independent variable. The placebo refers to a substance or treatment that has no therapeutic effect and is used as a control for comparison with the active treatment. The control group is a group in an experiment that is not exposed to the experimental treatment and is used as a comparison to determine the effects of the treatment.
