Incorrect

The question was: What is the mean for the group treated with active magnets?

Your Answer: 4

Answer and explanation: Your answer is incorrect. The correct answer is Just over 4.
The line in the box plot for the Treatment Group which is even with 4, represents the median pain rating for the Treatment Group. The median is the middle score of the group. The mean is represented by the plus sign (+) which is located at just over 4. The Treatment Group was treated with active magnets.
