Range divided by mean
WebbSimply take the standard deviation and divide it by the mean. Higher values indicate that the standard deviation is relatively large compared to the mean. For example, a pizza restaurant measures its delivery time in minutes. The mean delivery time is 20 minutes and the standard deviation is 5 minutes. Interpreting the Coefficient of Variation WebbThe standard deviation is approximately equal to the range of the data divided by 4. That’s it, simple. Find the largest value, the maximum and subtract the smallest value, the …
