WebMar 2, 2024 · Variance is the average squared difference of the values from the mean. Unlike the previous measures of variability, the variance includes all values in the calculation by comparing each value to the mean. Variance is expressed in much larger units (e.g., meters squared) Since the units of variance are much larger than those of a typical value of a data set, it’s harder to interpret the variance number intuitively.
