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? The 2009 cohort (n = 31) demonstrated a statistically significant improvement in literacy knowledge from pretest to posttest. → Pufpaff 2010

q2 · i? · causal · r1

Pretest-posttest study of the 2009 cohort (n = 31) in the replicated literacy unit. The mean pretest was 15.16 (SD = 2.46) and the mean posttest was 18.74 (SD = 2.77) of a maximum possible score of 26, with "positive gain scores ranged from 1 to 8 with a mean of 3.6 points."

"In 2009 (n= 31), the mean score for the pretest was 15.16 (SD = 2.46; range = 12 - 20) whereas the mean score for the posttest was 18.74 (SD = 2.77; range = 13 - 23) of a maximum possible score of 26."
