What is the mad of the data?
6, 15, 7, 14, 11, 13, 15, 15

I think 1) Find the mean, 2) subtract each # in the list from that mean 3) find the mean of those #s and that's the Mad. I've done this and my answer is not an option on the multiple choice.

PLEASE HELP

mean = (6+15+7+14+11+ 13 + 15 +15)/8 = 12

Median: arranged number from smallest to largest

6 7 11 13 14 15 15 15
Median: (13+14)/2 = 27/2 =13.5
Mode: 15
