Overestimation of Internal Consistency by K-R 20 in Tests Containing Interpretive Exercises.
Hanna, Gerald S.; And Others
Measurement and Evaluation in Guidance, v13 n4 p217-21 Jan 1981
Compared Kuder-Richardson Formula 20 and coefficient alpha (by blocks) reliability estimates for a reading comprehension test. On the average, K-R 20 exceeded coefficient alpha by about .05; that is, K-R 20 exaggerated the internal consistency of the test as would be expected from theory. Implications for counseling interpretations are discussed. (Author)
