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.
q3 i? An independent samples t-test found no significant pre-test difference between the audio input enhancement group and the control group. → Negari 2018

q3 · i? · causal · r1
Independent samples t-test on pre-test scores of the two intact groups (experimental M=5.17, SD=1.82; control M=5.90, SD=2.26), reported as "no significant difference (t (41) = 1.16, p>.05)"; homogeneity was further checked with an English-Beginner proficiency test.
"there is no significant difference (t (41) = 1.16, p>.05) in the performance of the two groups regarding th eir pre -test on English intensifiers."
