KOMPARASI KETEPATAN ESTIMASI KOEFISIEN RELIABILITAS TEORI SKOR MURNI KLASIK TESIS
Wahyu Widhiarso,
2008 | Tesis |The aim of this research is to examine estimation precisely among reliability coefficients and goodness of fit of models in classical theory. There are two scenarios in this research. First, comparing reliability estimation through 18 estimators on simulation data. Simulation data is generated by author that contain various combination along with true reliability value, sample sizes and measurement models also normal distribution data condition. The second scenario is comparing goodness fit of test four measurement models in classical theory (e.g parallel, tau equivalent, congeneric and error correlated) on simulation data and real data. The real data was collected on 2183 participant with Coopersmith Self Esteem Inventori (CSEI) that adapted on Indonesian version. This research found that, a) there are significance estimation difference emong reliability estimation among estimator in classical theory, b) goodness of fit of congeneric and error correlated model is higher than parallel and essentially tau equivalent model, c) goodness of fit of multidimensional model is higher than unidimensional model. Key word : Reliability, Reliability Estimation Precision, Goodness of Fit Model
