Correlation tells us that two variables are related, but it does not indicate which variable caused the change in the other. For example, just because there is a correlation between ice cream sales and crime rates does not mean that ice cream sales cause crime, or that crime causes people to buy more ice cream. There may be other variables, such as temperature or time of day, that affect both of these variables. Therefore, we cannot make causal conclusions based solely on correlational evidence.
