Each deviation in the numerator for variance is squared because
A) without squaring each deviation, the solution for SS would be zero.
B) this inflates the value for variance, making it more accurate.
C) without squaring each deviation, the solution could be negative.
D) without squaring each deviation, the solution for SS would be zero, and without squaring each deviation, the solution could be negative.

Question

Quizplus · Accepted Answer

Without squaring each deviation, the sum of deviations from the mean would always equal zero, resulting in a variance of zero. By squaring each deviation, the negative values are eliminated, and the data's variability is accurately represented.
