This tool will calculate the coefficient of variation of a set of data. The coefficient of variation is a measure of *spread* that tends to be used when it is necessary to compare the spread of numbers in two datasets that have very different means.

To perform the calculation, simply enter your data into the textbox below, either one score per line or as a comma delimited list, choose whether your data represents a population or sample (the default is sample), and then press "Calculate".
