Answer:
Binomial effect size display (BESD)
Step-by-step explanation:
Personality psychologists used the Binomial Effect Size Display (BESD) to show that a correlation of r= .40 is not small. BESD is a graphical representation of the correlation between a predictor and a criterion variable, that can be used to evaluate the magnitude of the effect size. It shows how well the predictor variable can discriminate between different levels of the criterion variable. With BESD, personality psychologists were able to demonstrate that even a correlation of r= .40 can have a significant impact on the ability to predict behavior from personality.
