The unstandardized partial slopes, also known as the regression coefficients, show the amount of change in the dependent variable (Y) for a unit change in one independent variable while holding all other independent variables constant (i.e., controlling for their effects). This is the definition of a partial slope or coefficient in multiple regression analysis.
