D)all of these

Question

Quizplus · Accepted Answer

All three strategies listed - holding a variable constant, matching, and random assignment to experimental groups - are commonly used to control confounding variables. Holding a variable constant involves keeping a particular variable the same for all participants or groups in a study, so that it cannot be a source of variation between groups. Matching involves selecting comparison groups that are similar on important variables that could be confounding factors. Random assignment helps to ensure that any potential confounding variables are distributed evenly across groups, reducing the likelihood that one group will have a particular confounding variable that causes an effect. Therefore, the best choice would be D - all of these.
