Group comparisons can be analyzed statistically in a matched-pairs approach (which associates each individual’s posttest score with his or her pretest score) or, when the groups are not composed of exactly the same set of individuals, as aggregations of scores.  Both provide you with useful information. When possible, we recommend using the matched-pairs approach for pretest posttest comparisons.
