Claims

EWIMS did not have a detectable impact on school data culture, though the overall scale effect size (Hedges' g = 0.27) favored EWIMS

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 i1 Differences between EWIMS and control schools on the overall school data culture scale and its subscales were not statistically significant, but the overall effect size was Hedges' g = 0.27. → Faria 2017

q2 · i1 · causal · r2

Exploratory school-level analysis using the 2015 end-of-year school leader survey (66 schools). The printed effect size was Hedges' g = 0.27 for overall data culture; the quote states the effect size "(Hedges' g) for the overall school data culture scale was 0.27". Subscale differences were not statistically significant at p < .05.

"However, the effect size (Hedges' g) for the overall school data culture scale was 0.27, suggesting that although not statistically significant, EWIMS schools reported modestly higher data culture than control schools"
