WebSep 16, 2024 · The co-efficient of variation (CV) is a statistical measure of the relative dispersion of data points in a data series around the mean. It represents the ratio of the standard deviation to the mean. WebIt is meaningful because it provides a baseline for the relationship between the two variables. The value of the regression coefficient, r, is 0.8. The value of the coefficient of determination, r^2, is 0.64. This tells us that 64% of the variation in the dependent variable can be explained by the independent variable.
