Dr. Smith developed a screening measure that is meant to predict the onset of eating disorders in teens and young adults. After doing a predictive validity design, Dr. Smith found that the new had a predictive validity r = +.5 in successfully predicting eating disorders. Assuming only this new measure is used to predict eating disorders, what percentage of the variance in the onset of an eating disorder is predicted using the new measure? _________% (1 point) Note: Only provide a NUMBER for bonus consideration – do not include any special characters (e.g., %) _______ Using Dr. Smith’s new screen device, what percentage of the variance in the onset of eating disorders is not accounted for using the new screening measure? _________% (1 point) Note: Only provide a NUMBER for bonus consideration – do not include any special characters (e.g., %) _______
