Variance is a measure of dispersion of data points from the mean. Low variance indicates that data points are generally similar and do not vary widely from the mean. High variance indicates that data values have greater variability and are more widely dispersed from the mean. The variance calculator finds variance, standard deviation, sample size n, mean and sum of squares.
