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? Experimental-class students who did practicum with recycle materials scored significantly higher on a basic science process skills test than control-class students using the university practicum kit (Kruskal-Wallis significance 0.000 < 0.05). → Setiyo Prajoko 2017

q3 · i? · causal · r2
Randomized posttest-only control group experiment with 83 Open University Surakarta students divided into experimental and control classes; hypothesis testing used the Kruskal-Wallis nonparametric test in SPSS 18 after normality failed. The article reports "Kruskal Wallis obtained significance of 0.000 <0.05". No effect size is printed.
"Based on Table 7, Kruskal Wallis obtained significance of 0.000 <0.05. The results showed that the working hypothesis was accepted, while the null hypothesis was rejected."
