Mode: 5,7
Median: 6
Range: 13 - 2 = 11
IQR (interquartile Range): 7 - 5 = 2
Mean: 6
M.A.D (Mean Absolute Deviation): 1.73
________________________________
( how I found the mean )
2 x 1 = 2
3 x 1 = 3
4 x 1 = 4
4 x 5 = 20
6 x 2 = 12
4 x 7 = 28
8 x 1 = 8
13 x 1 = 13
________________________________
2 + 3 + 4 + 20 + 12 + 28 + 8 + 13 = 90/15 = 6!
mean = 6!
____________________________________
(finding the M.A.D mean absolute deviation)
6 - 2 = 4
6 - 3 = 3
6 - 4 = 2
6 - 5 = 1
6 - 5 = 1
6 - 5 = 1
6 - 5 = 1
6 - 6 = 0
6 - 6 = 0
6 - 7 = 1
6 - 7 = 1
6 - 7 = 1
6 - 7 = 1
6 - 8 = 2
6 - 13 = 7
_____________________________
1 x 4 = 4
1 x 4 = 4
_____________________________
4 + 3 + 2 + 4 + 4 + 2 + 7 = 26/15 = 1.73
so the answer to your question should be 1.73!
