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.
