Subclaims¶

q2 i? The experimental group scored significantly higher than the control group on the posttest objective test. → Yang 2017 q2 i? The experimental group scored significantly higher than the control group on the posttest subjective summarizing test, with a smaller SD. → Yang 2017 (2)

Evidence¶

Yang 2017¶

Xiaoling Yang. (2017). On Non-English Majors' Strategy Training in English Reading Comprehension. English Language Teaching, 10(10). https://doi.org/10.5539/elt.v10n10p153

q2 · i? · causal · r1

Posttest comparison of the two groups on the objective test: experimental mean 74.918 (SD 5.880) vs control mean 72.759 (SD 8.490), U-value 1.605 (P=0.951), DF 117, which the article treats as "a significant difference".

"The results of Table 1 showed that there was a significan t difference between two groups in the objective test of the posttest."

Yang 2017 (2)¶

Xiaoling Yang. (2017). On Non-English Majors' Strategy Training in English Reading Comprehension. English Language Teaching, 10(10). https://doi.org/10.5539/elt.v10n10p153

q2 · i? · causal · r1

Posttest subjective (summarizing) test: experimental mean 17.392 (SD 3.342) vs control mean 10.529 (SD 7.493), t = 4.039 (P<0.0005), DF 115; two raters scored with inter-rater reliability rxx≈0.972.

"Since F= 5.026>170.01 (57,60), there was a significant difference between the two groups. Moreover, the SD of the experimental group was smaller than that of the control group (3.345 vs. 7.499), a conclusion could be made that students in the experimental group did better in summarizing than students in the control group."
