Incorrect

The question was: What was the range for the group that received the active magnets?

Your Answer: 6

Answer and explanation: Your answer is incorrect. The correct answer is 10.
The range is the difference between the minimum score and the maximum score. For the treatement group, the group who received the active magnets, the minimum score is 0 and the maximum score is 10. This makes the range 10 for the group receiving active magnets. 6 is both the range for the control scores and the score under which 75% of the treatment groups pain ratings fell.
