The standard deviationis derived from variance and tells you, on average, how far each value lies from the mean. It’s the square root of variance. Both measures reflect variabilityin a distribution, but their units differ: 1. Standard deviationis expressed in the same units as the original values (e.g., meters). 2. Varianceis … See more Different formulas are used for calculating variance depending on whether you have data from a whole population or a sample. See more The variance is usually calculated automatically by whichever software you use for your statistical analysis.
