The correct option is A True

Determining the mathematical expression for the sum of deviations:

We know that the sum of the positive deviation from the mean is always equal to the sum of the negative deviations. The mathematical expression for this is,

i=1n(xi-x)=0

Hence, the sum of deviations is always zero.

Therefore, the given statement is true.
