The pretest-posttest nonequivalent control group design reduces the threat of assignment bias and limits time-related threats and therefore is a quasi-experimental design.

Question

Quizplus · Accepted Answer

The statement is true. The pretest-posttest nonequivalent control group design is a type of quasi-experimental design that includes a control group and a treatment group, but participants are not randomly assigned to the groups. However, the design aims to reduce the threat of assignment bias by selecting participants for the treatment and control groups based on factors such as age, gender, and baseline performance. The design also includes pre-test and post-test measures taken to assess the effect of the treatment. By using a control group and pre-test measures, the design aims to reduce the impact of potential confounding variables and limit time-related threats, such as maturation or history effects.
