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? One-way ANOVA showed a statistically significant difference in WTC mean scores across the three classes of different sizes (F(2,27)=15.12). → Zeinab Moradi Khazaei 2012

q2 · i? · associational · r1
Observational study of three intact classes (5, 10, and 15 students) at an Iranian institute; one-way ANOVA on WTC indicators showed a statistically significant difference at the .05 significance level, with F(2,27)=15.12. No effect size is printed.
"the results of ANOVA indicated that there was statistically significant difference at the .05 significance level in WTC mean score for the three classes: (F (2,27)=15.12)"
Discussion¶
Related Claims¶
- Only the smallest class differs significantly from the other two; classes of 10 and 15 do not differ significantly — a narrower finding that bears on this claim
- WTC decreases as class size increases on both talk-time and turns of talk — related
