This claim: no standardized effect is recorded in observations/ for it yet, so no benchmark reading is possible.

q2 i? Learners in the FoF (dictogloss) group achieved significantly higher posttest scores than learners in the FoM and FoFs groups. → Saeidi et al. 2012 q2 i? The omnibus one-way ANOVA on posttest scores revealed a significant difference among the three instructional groups. → Saeidi et al. 2012

q2 · i? · causal · r1

Experimental pretest–posttest study of 70 Iranian university ESP students assigned to three instruction groups; one-way ANOVA on posttest scores gave F = 37.360, Sig. .000 (Table 2), and "The findings showed that learners' scores in FoF group were significantly better than those of FoM group, and both of them achieved better scores than FoFs group."

"The results of ANOVA analyses revealed a significant difference between the three groups (see Table 2), but to identify which instructional approaches produced the significant results further post-hoc analyses were conducted."
