Suppose You Perform an Experiment That Compares the Performance of an Experimental

question 38

Multiple Choice

Suppose you perform an experiment that compares the performance of an experimental group and a control group. You find that the mean of the experimental group is higher than the mean of the control group. Does this prove that the treatment enhanced performance?

• A) Yes, because the experimental group did better as a whole than the control group
• B) No, because you must compare variances, not means
• C) No, because the difference between the group could have occurred by chance, even if it was not very likely i.e., less than .05)
• D) Yes, because group averages are the traditional measure to use to compare two groups
