Table 1 Summary of Goodness Fit Indices for the Measurement Model (IDT and TAM)
Type of measure | Acceptable level of fit | Values |
|---|---|---|
Chi–square (χ2) | ≤ 3.5 to 0 (perfect fit) and (ρ > .01) | 3092.872/1169 |
Normed Chi–square (χ2) | Value should be greater than1.0 and less than 5.0 | 2.646 |
Root-Mean Residual (RMR) | Close to 0 (perfect fit) | 0.33 |
Normed Fit Index (NFI) | Value should be equal to or greater than 0.90. | 0.962 |
Relative Fit Index (RFI) | Value should be equal to or greater than 0.90. | 0.961 |
Incremental Fit Index (IFI) | Value should be equal to or greater than 0.90. | 0.955 |
Tucker Lewis Index (TLI) | Value should be equal to or greater than 0.90. | 0.944 |
Comparative Fit Index (CFI) | Value should be equal to or greater than 0.90. | 0.932 |
Root-Mean Square Error of Approximation (RMSEA) | Value below 0.10 indicates a good fit and below 0.05 is deemed a very good fit. | 0.041 |
