Problem: mean deviation {85,96,76,108,85,80,100,85,70,95} [ Calculator, Method and examples ]

Solution:
Your problem -> mean deviation {85,96,76,108,85,80,100,85,70,95}

Mean bar x = (sum x)/n

=(85 + 96 + 76 + 108 + 85 + 80 + 100 + 85 + 70 + 95)/10

=880/10

=88

 x |x - bar x| = |x - 88| 85 3 96 8 76 12 108 20 85 3 80 8 100 12 85 3 70 18 95 7 --- --- 880 94

Mean deviation of Mean
delta bar x = (sum |x - bar x|)/n
