q3 i? Funnel plot symmetry and the Egger test (t = 1.54, p1 = 0.07, p2 = 0.14) indicated publication bias was unlikely among the included studies. → Zhang 2021

Publication bias assessment (Figure 2 funnel plot plus Egger test) of the 20 included studies. The authors state the sample effect sizes were "symmetrically distributed on both sides of the average effect size", supporting robustness of the pooled estimate.

"The result showed that t = 1.54, p1 = 0.07, p2 = 0.14. Both the research data and the funnel plot indicated that the flipped classroom studies we included were less likely to have publication bias, and the combined effect size obtained was relatively robust and reliable."

Related Claims¶

• Funnel plot analysis showed no publication bias among the 15 studies included in the AR meta-analysis — related
• The pooled burnout–dropout intentions effect appears robust to outliers and minimally influenced by publication bias — related
• Publication bias is present in the embodied vocabulary learning literature, suggesting pooled effects may overestimate the true benefit — related
• Smaller, underpowered studies report larger flipped classroom effect sizes, indicating small-study and publication bias — reports the opposite
• No evidence of publication bias was found in the flipped classroom literature, though dissertations showed a larger (non-significantly different) effect size than journal articles — possibly the same claim (merge candidate)
• Publication bias tests and sensitivity analyses support the robustness of the pooled bilingual teaching effects — related
