Subclaims¶

q2 i? In a 2x2 factorial ANCOVA with pre-physics concept understanding as covariate, the treatment effect remained significant (F = 689.27), with adjusted means 85.60 (CAM) versus 65.57 (TM). → Kumar 2013

q2 · i? · causal · r1

2x2 factorial ANCOVA (treatment x gender) on 228 students with pre-physics concept understanding as covariate; the article reports "the adjusted F-value of treatment is 689.27, which is significant at 0.01 level". Adjusted means: CAM 85.60, TM 65.57.

"the adjusted F-value of treatment is 689.27, which is significant at 0.01 level. It indicates that the mean scores of physics concept understanding of students taught through CAM and TM differ significantly"
