Subclaims¶
Reading the evidence codes
q is the design tier, i the impact, n the sample, and the kind with its r
the rigour judged within that kind: what each code means.
This claim: no standardized effect is recorded in observations/ for it yet, so no benchmark reading is possible.
q2 i? Student scores based on items with calibration status 10 versus without it differ very little by grade and ethnicity, with correlations of 1.00 between Spanish RIT and Spanish NRIT. → Wang 2020

q2 · i? · design · r2
Descriptive comparison of person RIT means and SDs by grade (Tables 3.4 and 3.5) and ethnicity (Tables 3.6 and 3.7) for the selected monolingual and bilingual samples, scoring with versus without status 10 items. Mean differences are about one RIT decimal point and correlations between Spanish RIT and Spanish NRIT are 1.00; no effect size is printed.
"The difference between the monolingual results based on items with and without item calibration status 10 is very small for both grade and ethnicity, which indicates that the impact of treating the newly calibrated status 10 items as status XX items is very small and can be neglectable."
Discussion¶
Related Claims¶
- Adaptive testing explains why about one third of calibrated Spanish math items carry calibration status 10 — related
- Old (English-borrowed) and newly calibrated Spanish item RITs differ negligibly, with correlations of 0.98 and no statistically significant paired t-test differences — related
- Rescoring with new item parameters changed average ability estimates negligibly, with new and original scores correlated above 0.99 — related
- Outlier rates in Spanish item calibration are extremely low, which the authors take as evidence of very high calibration quality — related
- Socioeconomic status differences between bilingual and monolingual groups may determine study outcomes — related
