How to Calculate Covariance From a TI-84 Techwalla

WebThe value of the coefficient of determination is calculated by- r 2 = 0.329 2 = 0.1082. For percentage of variation explained by the model we need to multiply r 2 with 100.. r 2 *100 = 0.1082*100 % = 10.82%. So, 10.82% of total variation is explained by the linear relationship between the two variables. WebMay 17, 2024 · We can then use these values to calculate the coefficient of variation: CV = s / x. CV = 9.25 / 19.29. CV = 0.48. Both the standard deviation and the coefficient of variation are useful to know for this dataset. The standard deviation tells us that the typical value in this dataset lies 9.25 units away from the mean.
