Answer:
(C) zero
Step-by-step explanation:
The algebraic sum of the deviations of a frequency distribution from its mean =0
For example-
Let the value be 4,6,9,15,16
∴Mean=
5
4+6+9+15+16
=
5
50
=10
Deviation of 4 from 10=4−10=−6
Deviation of 6 from 10=6−10=−4
Deviation of 9 from 10=9−10=−1
Deviation of 15 from 10=15−10=5
Deviation of 16 from 10=16−10=6
∴Algebraic sum of the deviation(with sign)=(−6)+(−5)+(−1)+5+6=0
