Examining cronbach alpha, theta, omega reliability coefficients according to the sample size

Abstract

Differentiations according to the sample size of different reliability coefficients are examined. It is concluded that the estimates obtained by Cronbach alpha and teta coefficients are not related with the sample size, even the estimates obtained from the small samples can represent the population parameter. However, the Omega coefficient requires large sample sizes. Copyright © 2007 JMASM, Inc.
