The beta coefficient is used to compare the strength of a predictor within the model to predict the dependant variable or outcome so that the higher beta indicates more power of the variable to predict outcome. Because beta coefficient is potentially affected by the standard error of the variable, the standardized beta adjusted for this error is considered.
A value lees than 0.05 indicates a significant role for predicting outcome by the considered variable.
