Question

Quizplus · Accepted Answer

The bias due to biased selection is likely to impact this study, as the researcher has not provided any information on how the treatment group was selected from another school. This could result in a non-representative treatment group, making it difficult to draw meaningful conclusions from the study. The other options (bias due to history, posttest-only control-group design, and bias due to maturation) may also potentially impact the study, but the bias due to biased selection is the most likely to have an impact given the information provided.
