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? Between 2009 and 2011, student perceptions of Safety improved at the same rate in CoC and non-CoC schools; the difference in change was not statistically significant. → Rachel Levenstein 2011

q2 · i? · causal · r2

HLM analysis of student Safety measures from the My Voice, My School survey (2005-2011) found both groups improved "but at the same rate"; the student Safety measure "did not change significantly between 2009 and 2011 for CoC schools compared to non-CoC schools." No effect size is printed.

"Between 2009 and 2011, both CoC and non-CoC schools improved in Safety—but at the same rate. See Figure 1 for the trends since 2005, controlling for the variables specified above."
