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? Experimental-group participants reporting water and energy saving rose from 15 and 14 to 23 and 23 respectively, while control-group behaviors changed little between pretest and posttest. → Aykut Emre Bozdogan 2011

q2 · i? · causal · r1

Frequency analysis of answers on individual environmentally friendly behaviors (Table 3): the experimental group's reported water and energy saving rose markedly, no experimental participant reported doing nothing at posttest, and the article reports a 65% versus 4% rate of increase.

"While 15 of the preservice teachers said they took care with water consumption in the pretest, this number increased to 23 at the end of the experimental study. The case with energy consumption was also similar (pretest 14 people, posttest 23 people)."
