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? After a 45-day WhatsApp writing program, the experimental group scored significantly higher than the control group on the punctuation post-test. → Said Fathy El Said Abdul Fattah 2015

q2 · i? · causal · r1

Quasi-experimental post-test comparison of two intact groups of 15 fourth-level EFL students each; the experimental group (M = 13.93, S.D. 3.990) outscored the control group (M = 8.80, S.D. 3.750) on punctuation, with the reported "t value was 3.713" exceeding the tabulated value.

"Comparing the t value between the experimental and control group in punctuation marks shows that t value was 3.713 with the value of the tabulated t at the level (0.01) was .736."
