Reliability coefficients estimate the proportion of observed score variance that can be attributed to true score variance versus error variance. There are several ways of estimating test reliability because there are several different sources of variation in test scores. Briefly describe the following methods of estimating test reliability: a. test-retest method b. parallel forms method c. internal consistency method
