The dependent variable is the variable that is being measured or observed, which in this case is the number of words recalled. The independent variable is the variable that is being manipulated, which is the time given to study the word list (3 minutes for group A and 10 minutes for group B). A placebo is a harmless substance or procedure given to participants in a clinical trial as a control group, and is not relevant to this experiment. A control group is a group that is used as a standard for comparison, but it is not relevant to this experiment either.
