A correlation is a relationship between two things, or variables.

For example, it is generally true that the more junk food you eat, the fatter you get. This is a positive correlation - there is a strong relationship

A negative correlation means that there is a strong relationship between two variables, but in the opposite direction. For example, the older a second-hand car is, the lower the price.

Hope this helps.
