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? Eight leading scholars' rankings of five transcripts correlated .76 (Spearman rho) with the rank order predicted by the Ratio variables but only .23 with the rank order predicted by absolute frequencies. → Howe 2018

q2 · i? · associational · r2

Validation exercise in which five transcripts varying in Elaborated, Reasoned and the two Ratios were ranked for educationally productive dialogue by eight leading scholars who had endorsed most themes. The mean rank order correlated "rho) .76" with the Ratio-predicted order versus .23 for absolute frequencies.

"The mean rank order across scholars correlated (Spearman rho) .76 with the rank order predicted by the Ratios but only .23 with the rank order predicted by the absolute frequencies."
