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

23: In doing a [classical/quantum] physics problem, if my calculation gives a result very different from what I’d expect, I’d trust the calculation rather than going back through the problem.
