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? Paired t-tests found no significant pre-post FMCT difference in the experimental group (t(15)=0.84, p>.05) or the control group (t(14)=0.46, p>.05). → Buber 2017

q2 · i? · causal · r1

Paired samples t-tests within each group of the quasi-experiment. Experimental means moved from 8.56 to 8.00 and control means from 9.33 to 9.00, both decreases non-significant; equivalence was not tested.

"In Table 5, it is found that there isn’t any significant difference between pre and posttest results of experimental group’s scores in FMCT (t(15)=0.84, p>.05)."
