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.
q3 i? Journal publications had significantly larger effect sizes than dissertations and conference papers, consistent with publication bias. → Dimitris Anastasiou · Clare Nangsin Wirngo · Pantelis Bagos 2024

q3 · i? · quant-synthesis · r3
Moderator analysis of publication type across 40 journal and 18 grey-literature comparisons. Publication bias tests were significant (Begg p = 0.035; Egger p = 0.007), and trim-and-fill estimated 16 missing studies, attenuating the estimate to g = 0.403.
"journal publications had larger effect sizes than dissertations and conference papers, and this difference was statistically significant (g = 1.039 vs. 0.254, see Table 2)"
Discussion¶
Related Claims¶
- Published studies of simulation games report substantially larger effects than unpublished studies, indicating publication bias — related
- Egger's test suggests publication bias may be present, with the selection-model adjusted mean effect falling to 0.36 — related
- Publication bias is present to a varying degree, with published studies reporting larger belief and student-behavior effects than unpublished studies — related
- No evidence of publication bias was found in the achievement goal–dishonesty literature — related
- Studies published before 1998 report much larger private-schooling civic effects than studies from 1998 onward, which the authors treat as evidence of publication bias limited to earlier studies. — a narrower finding that bears on this claim
