Statistical contrasts are a tool for testing specific hypotheses and model effects, particularly comparing specific group means.
They allow you to answer questions that go beyond the standard model output, like comparing the outcome of two treatments when neither of them is the reference category. And determining whether there is an increasing or decreasing trend in the outcome as we move across the categories of an ordered categorical variable.
In this training, we explore the principles behind different types of statistical contrasts for factorial ANOVA and general linear models, how to set them up, and when we might choose to use them.
Note: This training is an exclusive benefit to members of the Statistically Speaking Membership Program and part of the Stat’s Amore Trainings Series. Each Stat’s Amore Training is approximately 90 minutes long.Date and Time
