One concern for a repeated-measures study is that the participants in one treatment may have different characteristics than the participants in the other treatment.

Respuesta :

The answer is false.

There is no worry in the repeated-measures trial that the participants in one treatment may differ in some ways from the participants in the other treatments. To ensure that there are no differences between the patients before getting the treatments, the repeated measures study either uses the same group of people for both treatments or matches the subjects in two groups on a number of variables. Therefore, it is unimportant to worry that the individuals in one treatment may differ from those in the other treatments in a repeated-measures study.

Which is a serious concern with a repeated-measures study?

  • Each participant in a repeated-measures experiment first takes part in one treatment condition before moving on to a different treatment condition.
  • The possibility that involvement in the first treatment could affect the participant's performance in the second treatment is one of the main issues with this kind of study.
