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? Cronbach's alpha calculated for the full FFL and for each of its four categories of leadership practices indicates good internal consistency. → McCullough 2016
