The question was: The middle 50% of the scores for the control group fall between:
Your Answer: 0-10
Answer and explanation: Your answer is incorrect. The correct answer is 8-10.
The middle 50%
on a boxplot is represented by the distance covered on the scale by the whole box. Therefore, the middle
50% of the Control Group is from the lower bound of the box, or 8, to the upper bound of the box, or
10. 0-10 is the middle 50% of the Treatment Group's score plus all the scores which fall within one
standard deviation of the mean.
