can you check if i have correct these 2 questions
find the outlier and tell how it affects the mean for:
-13, -16, -12, -16, -3, -14
the outlier is: -3
mean without outlier: 14.2
THE OUTLIER LOWERS THE MEAN BY : 1.9
Your math is correct, except that the mean in both cases would be negative, and the outlier would increase the mean.
