Coefficient of variation is a measure of the ratio of the standard deviation to the mean. In statistics it is abbreviated as CV. To calculate CV you take the standard deviation of the data and divide it by the mean of the data. Mean is another word for average. To calculate the average of a set of data, you add all the numbers and then divide by how many numbers you added.
How to Find a Coefficient of Variation: Overview. Use the following formula to calculate the CV by hand for a population or a sample. Ï is the standard deviation for a population, which is the same as âsâ for the sample. Î¼ is the mean for the population, which is the same as XBar in the sample. In other words, to find the coefficient of variation, divide the standard deviation by the mean and multiply by 100%.
