Question

Find the sum of the derivation of the variate values 2,6,9,12,11,8 from their mean


​

Answer 1

Answer:

0

Step-by-step explanation:

mean = sum of observation / no of observation

= 48 / 6

= 8

2 - 8 = -6

6-8=-2

9-8=1

12-8=4

11-8=3

8-8=0

sum of derivation of the variate values from their mean is

= - 6 - 2 + 1 + 4 + 3 + 0

= - 8 + 8

= 0
