1 GRA 6020 Multivariate Statistics The Structural Equation Model Ulf H. Olsson Professor of Statistics

2 Ulf H. Olsson Measurement Models Consequences of Measurement Error Biased estimates Does the Model fit the Data The Chi-square test The RMSEA approach Detailed evaluation of the model t.-values Reliability Validity

3 Ulf H. Olsson Cronbach’s alpha One can see from this formula that if you increase the number of items, you increase Cronbach's alpha. Additionally, if the average inter-item correlation is low, alpha will be low. As the average inter-item correlation increases, Cronbach's alpha increases as well.
