We must use standardized beta weights to compare the size of beta weights in multiple regression because the independent variables they represent are often measured with different units.

Question

Quizplus · Accepted Answer

Standardized beta weights are calculated by standardizing all independent variables to have a mean of 0 and a standard deviation of 1. This is done in order to compare the relative importance of each independent variable in the regression equation, since the variables may have different measurement units and scales. Using standardized beta weights allows for a fair comparison of the magnitude of the effects of different independent variables on the dependent variable.
