Quizplus · Accepted Answer

The control group and the experimental group in an experiment are treated exactly the same except for the independent variable, which is the variable being manipulated by the experimenter to observe its effects on the dependent variable. The dependent variable is the variable being measured, and extraneous variables are any variables other than the independent variable that can affect the outcome of the experiment. Replication refers to the repetition of the experiment to ensure the results are consistent and reliable.
