What is the MAD of the following data?
5, 1, 1, 8, 4, 5
And, please tell me how you do it?
Thank you.
First find the mean:
m = (5 + 1 + 1 + 8 + 4 + 5)/6 → 24/6 → 4
Mean Absolute Deviation:
MAD = (|5 - 4| + |1 - 4| + |1 - 4| + |8 - 4| + |4 - 4| + |5 - 4|)/6
MAD = (1 + 3 + 3 + 4 + 0 + 1)/6 → 12/6 → 2
.
