Coefficient of Variance (CoV) is a non-dimensional value calculated by dividing the Standard Deviation of a data set by the algebraic mean (or Average) of the same dataset. Thus CoV = STDEV/AVERAGE. So, in Excel, at the bottom of a column of numbers representing your data set, say in cells B39 to B58, make cell B60 = AVERAGE(B39:B58), B61 = STDEV(B39:B58) and B62 = B61/B60. CoV is frequently expressed as a percentage, so B62 could be = 100*B61/B60
