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? The task-based group's mean score rose enormously from pretest (M = 13.05) to posttest (M = 17.70). → Rajabi 2015 q2 i? The pretest-posttest difference for the task-based group was statistically significant (t = -6.941, df = 19, Sig. .000). → Rajabi 2015 (2)

q2 · i? · causal · r1

Paired pretest-posttest comparison of the task-based group (TBG, N = 20) on the researcher-made resumptive-pronoun test, reported in Results section 4.3. The pretest mean was "enormously less than that of the posttest"; no effect size is printed.

"It can be seen that in the TBG on the pretest, the mean score of the learners ( M = 13.05) is enormously less than that of the posttest (M = 17.70)."

Paired samples t test for the TBG reported in Table 5: mean paired difference -4.65000, t = -6.941, df = 19, Sig. (2-tailed) .000. No standardized effect size is printed, so impact is null.

"TBG Pretest – Posttest -4.65000 2.99605 .66994 -6.05219 -3.24781 -6.941 19 .000"
