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
