Analysis of covariance (ANCOVA) tests differ from ANOVAs in important ways, and can be extremely useful in inferential statistics.
Explain the purpose of ANCOVAs and their role in inferential statistics.
How does an ANCOVA differ from an ANOVA? When would we use one of these tests over the other?
What is meant be the term “covariate”?
Provide an example of a study where you would want to use an ANCOVA. Describe the variables (scale of measurement and type – independent or dependent), type of ANCOVA, rationale for using this type of test, and the covariate for this example.
