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? Design effects from aggregating individual data to groups are tolerable when there are moderate numbers of groups and few covariates, suggesting little information is lost in these cases. → Peter Z. Schochet 2020

q2 · i? · theoretical · r2
The article reports that "design effects from aggregation are tolerable with moderate numbers of groups and few covariates," indicating "little information is lost in these cases." No numeric design-effect values are printed in the available text.
"Furthermore, design effects from aggregation are tolerable with moderate numbers of groups and few covariates, suggesting little information is lost in these cases."
Discussion¶
Related Claims¶
- Ecological inference methods for subgroup analyses yield large design effects — reports the opposite
- Test-taking disengagement distorts both individual and aggregated test scores — related
- School-level aggregated scores on the computer-based PISA-Based Test for Schools were highly stable despite considerable differential engagement among schools — related
- E-M scoring leaves residual score distortion, suggesting some disengaged test responses are nonrapid rather than rapid guesses — related
- Responses used in effort-moderated scoring can sometimes reflect less-than-full, or partial, engagement, making E-M scores less trustworthy — related
