Notes. Prejudiced beliefs: Beta-values represent raw score value (range 1–5). β = Standardized beta-values.
1 School was controlled for, but did not contribute significantly in the model.
* p < .05, ** p < .01, *** p < .001. F-values are based on Type III sum-of-squares and corrected for non-orthogonality.
Since t-tests are uncorrected, F-tests are relied upon for significance testing of effects.
