Quizplus · Accepted Answer

The flaw mentioned in the question relates to the methodology used in the study, specifically the lack of information on how the treatment groups were formed. This suggests that the study is an experimental design, in which groups are randomly assigned to different treatments. The other options (survey, observational, and correlational) do not necessarily involve the formation of treatment groups, so they would not be affected by a lack of description of the group formation process.
