Correlation is a statistical measure that indicates the extent to which two or more variables change together. A positive correlation indicates that the variables are increasing or decreasing together (in parallel). A negative correlation indicates that as one variable increases the other decreases.
In this example, time spent sleeping correlated positively with the obtained test score.
In statistics, when the value of one event, or variable, increases or decreases as a result of other events, it is said there is causation. This is not the best conclusion for our example, since, for example, people who have slept 8 and 8.2 hours have the same test score.
