CV - Co-efficient of Variation Calculator
Use this online coefficient of variation (CV) calculator to calculate and compare the relative dispersion or variation of datasets. It outputs the standard deviation, mean, and CV with a detailed step-by-step workout to help you select the best competing statistical models.
Coefficient of Variation and its Application
Coefficient of Variation often abbreviated as CV, is a mathematical function or method used in the context of probability and statistics to compare the relative measure of dispersions or degree of variations between multiple data sets in statistical surveys or experiments. It's a unit less quantity calculated from the ratio of standard deviation to mean, generally used to select the best competing model by comparing the CV for different distributions. CV is also called as Relative Standard Deviation (RSD) that expresses which distribution has the lesser uncertainty or closely distributed around the mean. The higher or lower value of coefficient of variation represents higher or lower degree of uncertainty or dispersion of distribution around the mean or common behavior of the distribution. Users may use this coefficient of variation calculator to find the relative measure of dispersion to select the model with the least uncertainty.
Formula to Select Best Competing Statistical Model
The below is the mathematical representation for coefficient of variation. Find the standard deviation and mean values of sample distribution and substitute the values in the below formula to estimate the variabilities of different datasets relative to the central location of the data sets. The same formula is used in this coefficient of variation calculator to find the best competing model which has the lesser uncertainty or has the deviation very close to the mean.
