Question

the mean deviation from. the mean 10 of the data6, 7,10,12,13,a,12, 16 is​

Answer 1

Step-by-step explanation:

To find the mean deviation from the mean

Given Data is 6,7,10,12,13,α,12,16

Since Mean =10

M=

8

6+7+10+12+13+12+α+16

10=

8

76+α

10×8=76+α

80=76+α

α=4

Now , Mean Deviation from the mean

=

4+3+0+2+3+6+2+6 /8

=

8/26

=3.25
