Answer:
taking the pretest
Explanation:
A one-group pretest–posttest design is a type of research design generally used in behavioral research aimed at estimating the treatment effects on the sample. In this experimental design, the target group of participants is first pre-tested on the dependent variable and, subsequently, post-tested after the administration of a treatment. In consequence, the participants of the target group receive the same treatment and assessment. The problem of testing effects indicates that testing may become a problem when the pretest may change participant's behavior. When there are statistically significant differences between the pretest and posttest data, it is possible to support the working hypothesis.
