The two assessments are then compared, and the differences in both of them shall be taken to be the result of the effectiveness of the quizzes. The single group pretest/posttests design is recommended for this study (Jackson, 2009). Question 3 The possible confounds in each of the studies outlined include the notion that in the case of single group posttest design, the study does not provide for comparing the measures or variables. In the second study, the single group pretest/posttests design does not provide for how the observed changes in the study can be determined (Jackson, 2009). In this case, if the weekly quizzes are effective in improving learning, it is not possible to determine whether other factors contributed to the improved learning among students (Jackson, 2009). Therefore, in the absence of a comparison group, it becomes exceedingly difficult to determine whether the observable changes are because of the weekly quizzes or because of students taking more time to read at home. Question 4 Researchers might choose to use a single-case design when they want to ensure sensitivity to the individual participant variation versus group designs that show sensitivity to averages of factions (Trochim &. Donnelly, 2008).
