A method of estimating the true correlation between X and Y given the correlation between two unreliable measures of X and Y is by using the
A) shrinkage coefficient
B) reliability coefficient
C) correction for attenuation
D) corrected reliability index

Question

Quizplus · Accepted Answer

The method referred to in the question is known as the correction for attenuation, which involves adjusting the correlation coefficient obtained from two unreliable measures to estimate the true correlation between X and Y. The formula for this correction involves dividing the observed correlation by the square root of the product of the reliability coefficients of the two measures. Therefore, the best choice would be C, as the other options (shrinkage coefficient, reliability coefficient, and corrected reliability index) are not directly related to this method of estimating the true correlation.
