Correlation is a relationship between two variables, while causation is when an event or action happens and it appears to make another event or action happen.
Correlation is a relationship between two variables, while causation is when an event or action happens and it appears to make another event or action happen.
Scientists use causation when researching ways that organisms are adapted or have undergone natural selection, but they do not use correlation for this reason.
