How to calculate coefficient of variation in Excel?
Understand the Problem
The question is asking for the method to calculate the coefficient of variation using Excel. This involves steps that typically include calculating the mean and the standard deviation of a data set and then using these values to find the coefficient of variation.
Answer
Use `AVERAGE` for mean, `STDEV.P` or `STDEV.S` for standard deviation, and divide standard deviation by the mean to get CV.
To calculate the coefficient of variation (CV) in Excel, use the AVERAGE function to find the mean, the STDEV.P or STDEV.S function to calculate the standard deviation, and then divide the standard deviation by the mean.
Answer for screen readers
To calculate the coefficient of variation (CV) in Excel, use the AVERAGE function to find the mean, the STDEV.P or STDEV.S function to calculate the standard deviation, and then divide the standard deviation by the mean.
More Information
The coefficient of variation (CV) is a standardized measure of dispersion of a probability distribution or frequency distribution. It is often expressed as a percentage.
Tips
A common mistake is confusing STDEV.P and STDEV.S. Use STDEV.S if your data is a sample of the population and STDEV.P if it includes the entire population.
