R², amount of variance explained by IVs; ∆R² (R²Change), additional variance in DV; F, variance of the variables means; B, unstandardized Beta coefficient; β, standardized Beta coefficient (values for each variable are converted to the same scale so they can be compared); SE, standard error; t, estimated coefficient (B) divided by its own SE. If t<2 the IV does not belong to the model.
