The correct answer is B.
A collection of statistical models in which the observed variance in a particular variable is partitioned into components attributable to different sources of variation
Step-by-step explanation
In regression analysis, researchers usually find the value of R square or coefficient of determination which explains the total variation in the dependent variable or response variable due to independent variables and this happens for both numerical and categorical variables.
