The variance calculator finds variance, standard deviation, sample size n, mean and sum of squares. You can also see the work peformed for the calculation. Enter a data set with values separated by spaces, commas or line breaks. You can copy and paste your data from a document or a spreadsheet.

Variance Calculator Instructions. This calculator computes the variance from a data set: To calculate the variance from a set of values, specify whether the data is for an entire population or from a sample. Enter the observed values in the box above. Values must be numeric and may be separated by commas, spaces or new-line.

Population variance is a specific measurement that’s expected on a given population. Should the measurement vary widely from individual to individual, you would expect a high variance. Conversely, if the measurement varies by just a small amount, then you would expect a small variance. To simplify the calculation of a population variance for a set...
