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.

q3 i? Participants in the Text + Arithmetic condition outperformed participants in the Diagram condition and the Diagram + Arithmetic condition on total post-test scores. → Bas Kolloffel 2009

q3 · i? · causal · r1

Experiment with 123 pupils in a between-subjects pre-test post-test design across five representational-format conditions. The post-hoc LSD analysis showed "participants in the Text + Arithmetic condition outperformed participants in the Diagram condition"; overall format effect was F(4,119) = 2.57, P<.05.

"A post-hoc least significant difference (LSD) analysis revealed that participants in the Text + Arithmetic condition outperformed participants in the Diagram condition ( P\ .01), and participants in the Diagram + Arithmetic condition (P\ .05)."
