Answer:
Observations given are 5 , 8 , 10 , 15 , 22
Mean = ( sum of the observations ) /( number of observations )
= ( 5 + 8 + 10 + 15 + 22 ) / 5
= 60 / 5
Mean = 12
Sum of the deviations
= | 5 - 12 | + | 8 - 12 | + | 10 - 12 | + | 15 - 12 | + | 22 - 12 |
= | - 7 | + | -4 | + | -2 | + | 3 | + | 10 |
= 7 + 4 + 2 + 3 + 10
= 26
Sum of the deviation = 26
