Using Linear Models to Simultaneously Analyze a Solomon Four Group Design.
Williams, John D.; Newman, Isadore
Problems associated with the analysis of data collected using the Solomon Four Group Design are discussed. The design includes an experimental group and a control group that have been pretested and posttested, and an experimental and a control group that have been posttested only. A sample problem is approached in three different ways. First, the data are divided into two sets (those both pretested and posttested, and those posttested only) and analyzed using a simple t test. Second, the problem is visualized as a repeated measures design wherein the pretest is the first measure and the posttest is the second measure. Using this approach, the data can be analyzed with regression techniques. Third, if the design were seen as a six group design, a one-way lay-out or a three-way lay-out are possible. Both options are discussed, including the appropriate restrictions and multiple comparison techniques. (CM)
