Therefore, each sum of squares of deviations is the times of the consisitent and unbiased estimate of variance. so, if the division is reasonable, the sum of squares of deviations attained through the data to be grouped and the one attained through history data should be very close
這樣，由於每個類內離差平方和為該數據所屬分佈的方差的相合且無偏的估計的倍數，故如果分類合理，則由待分數據得到的離差平方和應與由歷史數據得到的離差平方和相接近。
