If you want to calculate the variance of your data, simply copy your data into the upper table, select one or more variables and click on "Calculate Variance" in the options. The variance is a measure of the dispersion of your data from the mean. A low variance indicates that your data does not deviate much from the mean. A high variance indicates that the data values have a greater variability and deviate more from the mean. To obtain a dispersion parameter with the same unit as the input data, simply use the standard deviation calculator.
