The question was: What is the mean for the group treated with active magnets?
Your Answer: Just over 8
Answer and explanation: Your answer is incorrect. The correct answer is Just over
4.
Although the plus sign (+) does
represent the mean, the box plot labled Control Group, which contains the + at just
over 8, represents the control group. The control group was not treated with active
magnets. The control group was given inactive magnets as a placebo. Therefore, the
correct answer is just over 4. This is the approximate place of the +, or mean, on
the box plot for the Treatment Group.
