Coefficient Of Variation Formula

In statistics, coefficient of determination, also termed as r 2 is a tool which determines and assesses the ability of a statistical model to explain and predict future outcomes. In simple words, it shows by what percentage data varies from its mean. Coefficient of variation of one data set is lower than the coefficient of variation of other data set, then the data set with lower coefficient of variation is more consistent than the other.

By dividing the within assay standard deviation by the overall mean:

Coefficient of variation formula. We can see that the coefficient of variation for this dataset is 49.3%. Formula for coefficient of variation Cv = σ / μ * 100 = (29.060/58.933) * 100 = 49.3%.

A coefficient of variation can be used to record changes in data over time and aid in business decisions. Investors use it to determine whether the expected return of the investment is worth. Find what coefficient of variance for given data?

This measure is used to analyze the difference of spread in the data relative to the mean or average value. Compute coefficient of variation for the following frequency distribution. Sample formulas vs population formulas when we have the whole population, each data point is known so you […]

Within the lab, it is mainly used to determine how reliable assays are by determining the ratio of the standard deviation to the mean. To calculate the coefficient of variation (cv), the formula in i5 is: The coefficient of variation of a = 191.

The result is a decimal value, formatted with the percentage number format. The coefficient of variation of b = 114. Thus, in the investment scenario, the formula of the coefficient of variation should be,

As with any statistic, using a coefficent of variation calculator has its good uses and situations where cv is not the appropriate statistic. Where, c v = coefficient of variation σ = standard deviation μ = mean. When comparison has to be made between two series then the relative measure of dispersion, known as coeff.of variation is used.
