Subclaims¶

q3 i? In the language-level MANCOVA the interaction of gender with year was not significant (p = .19); the same held in the difficulty-level analysis (p = .29). → Lowrie 2010

Evidence¶

Lowrie 2010¶

Lowrie, Tom and Diezmann, Carmel. (2010). Solving graphics tasks: Gender differences in middle-school students. Learning and Instruction. https://doi.org/10.1016/j.learninstruc.2009.11.005

q3 · i? · associational · r2

Gender-by-year interaction test within the 3(year) x 2(gender) x 6(graphical languages) MANCOVA with Raven's covariate. The article reports "The interaction of gender with year was not significant"; a parallel test in the difficulty-category analysis was also non-significant (p = .29). No effect size is printed for either interaction.

"The interaction of gender with year was not significant, Pillai’s trace = .016, F (6, 2040) = 1.34, p = .19, ns ."

Discussion¶

Learner Variables¶

• Gender — predictor: outcomes differ by group: a gap reflecting circumstances and treatment, not a cause
