Compute the F-value for a hierarchical multiple regression study, given an R-square value for a set of predictor variables A, an R-square value for the sum of A and another set of predictor variables B, the number of predictors in sets A and B, and the total sample size. The calculator computes the F-value associated with the addition of set B, which can provide useful insights for analytics studies that rely on hierarchical regression. Please provide the necessary values, and then click 'Calculate'.
