Mean divided by variance
WebDivide by the number of values to get the mean: 23/5 = 4.6; Subtract the mean from each value to get the numbers in the second column. Square each number in the second column to get the values in the third column. Total the numbers in the third column: 5.2; Divide this total by one less than the sample size to get the variance: 5.2 / 4 = 1.3 WebApr 30, 2024 · Variance is defined as a measure of dispersion, a metric used to assess the variability of data around an average value. It is a statistical measurement used to determine the spread of values in a data collection in relation to the average or mean value. Variance is divided into two main categories: population variance and sample variance.
