Quizplus · Accepted Answer

The two key features to an experiment are manipulation, which involves changing an independent variable to observe its effect on a dependent variable, and random assignment, which involves randomly assigning participants to experimental groups to control for individual differences that could affect the results. Option B is incorrect as correlation does not involve manipulation of variables. Option C is incorrect as correlation is not a key feature of an experiment. Option D is incorrect as predictability is not a key feature of an experiment.
