Question

Quizplus · Accepted Answer

A quota matrix can be used to ensure that the experimental and control groups are matched on relevant characteristics, such as age, gender, or prior experience, which may affect their preferences. This helps to minimize the potential confounds and increase the internal validity of the study. The other options do not directly address the issue of group matching. A double-blind study is used to prevent bias in the administration and interpretation of the treatment or intervention, but it does not ensure group equivalence. A pretest and a posttest are used to measure the change or difference in the dependent variable between the two groups, but they do not control for the initial differences. Compensation is a form of payment or reward for participation, but it does not affect group matching.
