Reliability coefficients can be interpreted as the proportion of variation in observed scores that can be attributed to actual differences among people on some trait versus random factors that have nothing to do with the measured characteristic or trait. Discuss how you would interpret the hypothetical reliability coefficients in the following examples:
a. The reliability of an intelligence test is.82
b. The reliability coefficient of the weight scale in the university fitness center is .97
c. The reliability of a self-esteem test is .90
