A researcher finds a correlation of r=0.50r = 0.50 between a self-reported measure of weekly exercise hours and a physiological measure of cardiovascular health. It is later discovered that the self-reported hours are unreliable and contain significant random measurement error. If the researcher were able to obtain the true, error-free exercise hours for each participant, how would the correlation with cardiovascular health most likely change?
