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.
At the other hand, the red-cell distribution width coefficient of variation is expressed as a percentage and is calculated from the standard deviation and the mean corpuscular volume. In other words, the RDW (CV) is dependent upon the size of the red blood cells. Normal values lies between 11.6 â 14.6%.
