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.

q3 i? Groups C and D showed no statistically significant increases in any dependent variable in the planned gain contrasts. → Bellhäuser 2022

Evidence

Bellhäuser 2022

Bellhäuser, H., Liborius, P., & Schmitz, B. (2022). Fostering Self-Regulated Learning in Online Environments: Positive Effects of a Web-Based Training With Peer Feedback on Learning Behavior. Frontiers in Psychology, 13, 813381. https://doi.org/10.3389/fpsyg.2022.813381

q3 · i? · causal · r2

Planned pre-to-post gain contrasts in the randomized four-group trial: "Groups C and D showed no statistically significant increases in any dependent variable." This shows no detected gain for the diary-only group; equivalence was not tested.

"Groups C and D showed no statistically significant increases in any dependent variable."
