When considering the practical or clinical significance of the finding, the psychologist would be concerned about all of these factors. The financial cost of implementing the treatment is an important consideration for determining whether the treatment is practical. The external validity of the finding is important for determining whether the results can be generalized to other populations or settings. Confounding variables can affect the validity of the study, therefore, the researcher should ensure that the study is free of such variables.
