Review each of the three sample experimental designs (i.e., pretest-posttest control group, time-series (repeated measures), and factorial) within the articles assigned for this week’s readings.
For each of the articles, define the experimental design used, specifically discussing the variables and procedures. The use of tables or figures may help to explain the workings of each experimental design. Summarize the results, and then explain how the conclusions relate to the hypotheses. Finally, determine how uncertainty was minimized and validity supported.
Length: 7 pages, not including title and reference pages. Be sure to cite and reference the required articles.
