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 i2 The correlation between treatment and argumentation skill score was r = .30, rated moderate, while all other variables showed negligible correlations. → Andrew C. Thoron 2012

q3 · i2 · causal · r2
Pearson Product Moment correlations among argumentation skill, grade, gender, ethnicity, SES, and treatment in the quasi-experimental sample. The article reports "r = .30" between treatment and argumentation skill, rated moderate by Davis's (1971) terminology; demographic correlations were negligible (e.g., .03–.16).
"Negligible correlations between all variables were found with the exception of the correlation between treatment and argumentation skill score. The relat ionship between the argumentation skill score and treatment r = .30 was found to be moderate."
