The unit introduces the principles of causal inference and basics of linear regression models. After this unit, you should
- Understand the three conditions for causality and why you cannot Interpret regression results as evidence of causality unless the regression is used as a part of a research design that takes the temporal order of cause and effect into account and more importantly eliminates rival explanations.
- Understand that regression (and other analysis results) need to be interpreted and explained to a reader in a way that makes then understandable for people that do not know statistical analysis very well. You should also know that p-value is not the main result but simply indicates which regression coefficients you should probably pay more attention to when interpreting the results.
- Understand that statistical analysis is not rocket science, but a collection of fairly intuitive ideas and simple mathematics. (If you go beyond regression, then the math can get a bit more complicated.)
