The final is a 180 minutes closed-book examination covering all of the material from class.

The exam format is as follows:

• One question on the fundamentals of experimental designs (blocking, randomization, etc.)
• One question on reproducibility/replication crisis
• 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
  • contrasts and pairwise comparisons
