Question

In a one-group pretest-posttest design affected by the problem of testing effects, the reduction found on the posttest is likely to be the result of _____

Answer 1

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.
