This means there is a relationship between the two events, hours worked and income and also that a change in one event (hours worked) causes a change in the other (income). This is causation in action! Causation indicates a relationship between two events where one event is affected by the other. 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.
Correlation is a statistical measure (expressed as a number) that describes the size and direction of a relationship between two or more variables. A correlation between variables, however, does not automatically mean that the change in one variable is the cause of the change in the values of the other variable.Causation indicates that one event is the result of the occurrence of the other event; i.e. there is a causal relationship between the two events.f the correlation coefficient has a positive value (above 0) it indicates a positive relationship between the variables meaning that both variables move in tandem, i.e. as one variable decreases the other also decreases, or when one variable increases the other also increases.
