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? At post-test, the experimental group made significantly fewer grammatical errors than the control group. → Al-Hazzani and Altalhab 2018

Al-Hazzani and Altalhab 2018¶
Nahla Al-Hazzani, Sultan Altalhab. (2018). Can Explicit Written Corrective Feedback Develop Grammatical and Lexical Accuracy of Saudi EFL Learners? International Journal of Education & Literacy Studies, 6(4). https://doi.org/10.7575/aiac.ijels.v.6n.4p.16
q2 · i? · causal · r1
Independent Sample t-test on post-test grammatical errors: control (n=21, M=5.19, SD=2.04) versus experimental (n=29, M=3.31, SD=1.65); the article reports t=3.600, p=0.001. The most prominent errors were "the misuse of prepositions, nouns, verbs, the omission of articles". No standardised effect size is printed in the quoted finding.
"Table 3 shows statistically significant differences between the number of student errors regarding grammar. This is favor of the control group students, with an average number of errors amounting to (5.19) compared to (3.31) for the experimental group."
