The Danger of Mixing up Causality and Correlation
While a relationship may exist, that does not mean it is a cause-and-effect relationship. We may say that one variable is independent and the other dependent, but this is only in a mathematical sense and it does not indicate cause and effect. There are much more sophisticated tests that attempt to establish causal relationships, but we will not study those in this course.
Correlation does not imply a cause-and-effect relationship between variables.
By recognizing this and discussing other contributing variables within the situation, you can demonstrate critical reflection and understanding of mathematics, two of the criteria your IA is assessed for.
1) Why is it dangerous to mix up Correlation and Causation?
2) Give one example from the video of how correlation was incorrectly used to imply causation.
3) Provide one example, not mentioned in the video, of a real-world correlation that you have experienced in your life or read about in the news. What other variables may have contributed to that relationship?
