Question

Quizplus · Accepted Answer

Matching helps to increase the chance of detecting the effect of the experimental manipulation by creating two groups that are similar in all relevant aspects except for the variable being manipulated. This allows for a better comparison between the two groups and a clearer determination of the effect of the manipulation. Matching does not eliminate the need for a control group, produce a normal distribution of scores, or reduce the number of scores that must be discarded.
