Table 1 Classical/quantum splits on the bifurcated CLASS questions. The p values are determined with the Bhapkar test and corrected using the Holm-Bonferroni method. Items with significant splits at the α = 0.05 level are indicated in italic

From: Splits in students’ beliefs about learning classical and quantum physics
