what’s the difference between correlation and causation?
In: Other
Let’s the that there are two group of people, 100 in each group.
Group A has 75 happy people (who each gave their happiness a score of more than 5 out of 10). There are also 75 people in group A who are healthy and don’t take any medications.
Group B has only 30 happy people. There are also 30 people in group B who are healthy and don’t take any medications.
You can see that there appears to be a correlation between health and happiness. However, we don’t know from this information whether being happy causes good health, or if being in good health causes happiness. We only know there is a correlation, and we don’t know what the causation is.
