There are four types of experimental designs: independent measures, repeated measures, matched pairs, and quasi-experimental designs. Almost every experiment can be conducted using either a between-subjects design or a within-subjects design. a technique for controlling progressive error by using some subset of the available sequences of treatment conditions. Within each of these blocks, the conditions occur in a random order.
