q3 i3 A repeated measures multivariate ANCOVA revealed a significant gender difference across the six graphical languages (partial η2 = .15), with Raven's score a significant covariate (partial η2 = .50). → 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 · i3 · associational · r2

Omnibus repeated measures MANCOVA on pooled GLIM decoding scores with gender as between-subjects factor, the six graphical languages as within-subjects factor, and Raven's test as covariate. The analysis "revealed statistically significant differences between the performance of boys and girls across the six graphical languages" (partial η2 = .15) and a strong covariate effect (partial η2 = .50).

"A repeated measures multivariate analysis of covariance with gender as be tween subjects factor , the six graphical languages as within subjects f actor and score on Raven’s test as co variate revealed statistically significant differences between the performance of boys and girls across the six graphical languages, F (6, 309) = 9.37, p < .001, partial η2 = .15, with a significant effect for the covariate, F (6, 309) = 50.47, p < .001, partial η2 = .50."

Discussion¶

Learner Variables¶

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

Related Claims¶

• Boys outperform girls on graphics tasks classified as Axis and Map graphical languages — a narrower finding that bears on this claim
• The gender gap in graphics decoding remained stable over three years, with no gender-by-year interaction — related
