- One question on key concepts (power, effect size, multiple testing).
- One question on advanced topics (mixed models, causal inference and mediation analysis, etc.)
- Two data analysis questions, using completely randomized or blocked designs (between-subjects or within-subject) with multi-way analysis of variance, ANCOVA, mixed model, with specific questions on various aspects including
- parametrization of ANOVA
- adequate setup of model
- interaction plots
- use of different tests and methods
- calculation of degrees of freedom of the model / sample size
- conclusions related to output of tests
- interpretation of effect sizes
