The Project Management Institute, however, endorses the accepted convention that a negative variance is a bad thing, and a positive variance a good thing. A variance is the difference between the projected budget and the actual performance for a particular account. A negative variance means that the budgeted amount was greater than the actual amount spent. A positive variance means that the budgeted amount was less than the actual amount spent. Note there is some debate over whether a negative variance means an underrun or an overrun.
That formula is. a = [k/(k-1)][1 - (Ss i 2 / s X 2)], where k is the number of items, Ss i 2 is the sum of the individual item variances taken over all k items, and s X 2 is the scale variance. Since the term in the first set of brackets is always positive, a will be negative if and only if. Ss.
