Step 1a: Differences in scores across groups using education in years | ||||
---|---|---|---|---|
| ||||
Group | Estimate | Standard error | p value | Cohen’s d |
Male sex | −.069 | .051 | .176 | 0.019 |
Age | −.106 | .052 | .039 | 0.316 |
Education | .324 | .048 | <.001 | 0.096 |
Language | −.086 | .052 | .095 | 0.024 |
Step 1b: Differences in scores across groups using WRAT scores | ||||
| ||||
Male sex | −.060 | .048 | .212 | 0.016 |
Age | −.077 | .049 | .112 | 0.256 |
WRAT | .477 | .042 | <.001 | 1.24 |
Language | −.061 | .049 | .213 | 0.017 |
Step 2: Language group differences across letter tasks | ||||
| ||||
Letter ‘‘F’’ | .005 | .035 | .881 | — |
Letter ‘‘A’’ | −.005 | .034 | .873 | — |
Letter ‘‘S’’ | .001 | .035 | .986 | — |
Note.‘‘—’’ indicates not applicable. Step 2 was only conducted once across the two models because education and WRAT scores were not involved in assessing differential test effects. The effective sample size was 395, given that nine cases had missing values. WRAT = Wide Range Achievement Test.
