Correlation and Causality
Understanding why correlation does not imply causality (even though many in the press and some researchers often imply otherwise).

Explain that a correlation does not establish that there is a causal relationship
A correlation is a relationship between two variables. If both variables increase, or both variables decrease, this is described as a positive correlation. If when one variable increases the other decreases (or vice versa) this is described as a negative correlation.

A correlation can be identified from observations without a scientific experiment. However, just because there exists a relationship between two variables, this does not indicate that there is necessarily a causal relationship between the two - there may be other variables influencing the relationship which have not been shown.

To establish cause in a relationship a controlled scientific experiment must be done.
