Subclaims¶

q3 i? The experimental group had a smaller post-test standard deviation (7.9 vs 9.5), which the authors read as more converged understanding. → Musasia 2016

q3 · i? · causal · r1

Descriptive comparison of post-test standard deviations from the global comparison of post-test results; the article interprets the smaller spread as the experimental group having "converged more in their understanding of the topics".

"The standard de viation for experimental group was 7.9 and that of control group was 9.5. This indicates that the experimental group had converged more in their understanding of the topics compared to the control group who still had a lar ge spread in their understanding."
