In a concept formation study, 12 subjects were randomly assigned to three different experimental conditions and then given four trials in the solution of a problem. For each trial, the number of minutes taken to solve the problem was recorded. The results were as follows:
(See the attached file for data table)
a) State and verify the model assumptions
b) Assuming all model assumptions are valid, what do the data indicate? Discuss your findings.
This is an example of the basic repeated measures experiment where the study is a completely randomized design (treatments are randomly assigned to experimental units with no blocking factors), and then 4 measurements are made on each unit over time. The tool used for the analysis was SAS.
