In an experiment, the independent variable is the variable that is manipulated, which in this case is the different amount of time given to study the word list (3 minutes for group A and 10 minutes for group B). The dependent variable is the variable that is measured, which in this case is the number of words recalled. Therefore, the number of words recalled is the dependent variable. Placebo refers to a fake treatment given to a control group, and control group refers to a group that is used as a reference for comparison but does not receive the treatment being tested, neither of which apply to this scenario.
