Adding an independent variable to a multiple regression model will generally increase the explained variation (SSR) because the model can account for more variability in the dependent variable with more predictors. Consequently, the multiple coefficient of determination (R^2) will also increase, as it measures the proportion of the variance in the dependent variable that is predictable from the independent variables.
