Imagine, for example, that participants judge the guilt of 10 attractive defendants and 10 unattractive defendants. A limitation is that while main effects of factors can be tested, interactions cannot be tested. Eg.

Crossover studies are a commonly used within-cluster design, which provides each cluster with a random sequence of strategies to counterbalance order effects in repeated measure designs. Counterbalancing ensures each condition is tested equally first or second. Figure 6.2shows some hypothetical results in which participants in a treatment condition improved more on average than participants in a no-treatment control condition. WebThe primary advantage of this approach is that it provides maximum control of extraneous participant variables. One problem with coin flipping and other strict procedures for random assignment is that they are likely to result in unequal sample sizes in the different conditions.

Here, instead of randomly assigning to conditions, they are randomly assigned to different orders of conditions. Researchers, however, rarely perform optimal analyses of these designs and, as a result, reduce the power of their experiments.

Thus random assignment plays an important role in within-subjects designs just as in between-subjects designs. When the procedure is computerized, the computer program often handles the random assignment. Within-subjects experiments have the advantage of controlling extraneous participant variables, which generally reduces noise in the data and makes it easier to detect a relationship between the independent and dependent variables. Under these circumstances, changes in data can be attributed to the IV. Fortunately, there are several solutions to this problem.
