q2 i? The Kruskal-Wallis test for conceptual understanding yielded Hcal = 1.95, which exceeded the Chi Square critical value at α = 0.90, df = 1, leading to rejection of H0. → Sinaga 2015

q2 · i? · causal · r1

Kruskal-Wallis hypothesis test comparing experimental (scaffolding) and control (expository approach) classes on conceptual understanding of electromagnetism. Hcal = 1.95 fell on the right side of the critical value at α = 0.90, df = 1, so H0 was rejected. No effect size is attached to this test statistic.

"The calculation resulted in Hcal = 1.95; then the H cal was consulted with the Chi Square ( χ 2 ) distribution for α = 0.90, and df = 1"
