Quizplus · Accepted Answer

Using more than one dependent measure allows the investigator to determine if the independent variable has a consistent effect across multiple measures or if it affects some measures more than others. This information can help the investigator better understand the underlying processes at work and can strengthen the overall conclusions of the study. The other answer choices do not accurately reflect the reasons why an investigator might use multiple dependent measures.
