The Estimation of Reliability for Multidimensional Scale Using Different Extractions and Sample Sizes
Abstract
The purpose of this research was to study and compare the reliability of Allen’s
method (ΩW) and McDonald’s method (ωMD) using a NEO Five – Factor Inventory
Scale and three different extractions with three different sample sizes. The sample was freshmen
of Rajamangala University of Technology in Bangkok area. The results of the research were as
the reliability of multidimensional scale from different extractions within the different sample
sizes when using ΩW and ωMD were different with statistical significance at the level of .05.
The estimation of reliability of multidimensional scale was most appropriate when using
3,000 pseudo populations as the representative of large sample. The extraction of generalized
least squares or principal factors with ΩW should be used with the sample sizes of 100 and 200
while the extraction of principal factors with ΩW should be used with the sample size of 500.
