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.

q3 i? The experimental group's post-test mean rating (5.73) was significantly higher than the control group's (3.80) on the coherence and cohesion components. → Paziraie 2013

q3 · i? · causal · r2

True-experimental pre-post study: 60 intermediate Iranian EFL learners randomly split into experimental and control groups; independent t-test on post-test ratings showed "a significance difference between the mean scores of two groups (5.73, and 3.80)" with t=8.942, p=0.0001. No standardized effect size is printed.

"In addition the difference between the means of the scores of the two groups is statistically significant ( t=8.942, p=0.0001<0.05). That is the results of the t-test showed that there was a significance difference between the mean scores of two groups (5.73, and 3.80)."
