Causation
- Causation is when changing one variable affects another variable
- Bi-variate data is created by measuring two things from each item in a sample
- Scatterplots can show if there is a correlation between two variables
- Correlation does not imply causation
- Correlation can provide evidence to back up a theory
- No correlation suggests no causation between two variables
- Common causes can create a correlation between two events
- Correlation can be found by coincidence
- Larger samples reduce the chance of finding a correlation by coincidence
- Extra data does not help identify a potential common cause behind a correlation
