- Conditional Standard Error of Measurement (CSEM) Equating Reporting Scale Scaling
In this study we investigated when an equating conversion line is problematic in terms of gaps and clumps. We suggest using the conditional standard error of measurement (CSEM) to measure the scale scores that are inappropriate in the overall raw-to-scale transformation.
