The larger the absolute value of a standardized beta coefficient, the more relative importance it assumes in assuming a role as a screening device the standardized beta coefficient predicting the independent variable predicting the dependent variable A researcher must work with a number of of the various levels of the dependent variable paired with different levels of the independent variable to compute a (intercept) and b (slope). observations errors small samples large samples In using the Pearson product moment correlation, negative correlation coefficients reveal that the relationship is opposite: As one variable increases, the other variable increases. True False A researcher can test the null hypothesis that no differences exist between the two group means (or percentages) by using a confidence interval test reliability test differences test correlation test
