Sentence examples for mean trait level from inspiring English sources

False positives increased when items were very easy to endorse and when there with mode differences in mean trait level.

A significant intercept slope interaction indicates that an individual's mean trait level is related to the way the trait changes with age.

With the exception of binary variables (i.e., IRT model, difference in CAT vs. P&P mean trait level), predictors were normalized by dividing each variable by two standard deviations prior to analysis [ 42].

For the CrI procedure, size of DIF and difference in mean trait level by mode significantly and positively predicted false-positive DIF results, whereas item difficulty was significantly and inversely associated with false positive mode DIF.

Based on AUCs, item difficulty was the single best predictor of false positives in DIF identification for both RZ and CrI, followed by difference in mean trait level between modes.

Though not significant at the univariate level, mean difference in mean trait level by mode of 1 logit was significantly and inversely related to true mode DIF detection in the multivariate model.

Since measures with mean trait levels of 0 or 1 logit were simulated, items in this range of difficulty would be most frequently administered.

Though differences in mean trait levels were examined, deviations from prior assumptions concerning parameter variances or distribution types were not examined.

False positive rates also increased as the difference in mean trait levels between the CAT and P&P modes increased from 0 (RZ: 2.8%; Δ CrI: 3.0%) to 1.0 logits (RZ: 4.4%; Δ CrI: 5.8%).

Items with large DIF effects and mean differences in trait level between groups limit the effectiveness of matching, as has been observed in previous DIF studies [ 50- 53].

In addition to the effect of item parameters, false positive DIF results were significantly associated with DIF size and mean difference in trait level between CAT and P&P administration modes.
