This video introduces a new type of statistical question: which model is best and by how much? We want to persuade you to adopt an attitude. Here are the principles that got us to this point:

  1. variables: the way we split the world into pieces we can study
  2. relationships between variables: the way we recognize how variability works
  3. likelihood: uncertainty about the population given just a sample
  4. covariation: all variables may be related to each other
  5. statistical models: a way of stating precisely what we know about a population
