First, we compute the variance by taking the sum of squares and divide that by N which is the number of data points in the same. It is average squared deviation of each number from its mean. The point is a squared number is always positive and N is always positive so the variance must always be non-negative. ( It can be 0).

The variance is a measure of the dispersion of a set of data points around their mean value.

It would not make sense for it to be negative.
