Differences between the first and last measurement are then attributed to the iv (stimulus) Experimental and control groups should be as similar as possible. Probability sampling where all members of a population have an equal chance of being selected. Unrealistic in an experimental setting due to required sample size. Randomly assigning subjects to the experimental and control groups. Group of subjects which is administered the stimulus. Group of subjects which is administered no stimulus. Helps establish whether the stimulus itself, or outside unrelated events, are having an effect on. Samples selected with probability theory, using some sort of random selection mechanism.
