This PsycholoGenie article explains spurious correlation with examples.A correlation is a kind of association between two variables or events. Assume that the hidden variable is A and two variables which are spuriously correlated are B and C. In such scenarios, a graph structure similar to B<-A->C exist. These two variables falsely appear to be related to each other, normally due to an unseen, third factor.For example, over the past 30 years the price of cinema tickets has increased and the number of people attending the cinema has also risen. The word ‘spurious’ has a Latin root; it means ‘false’ or ‘illegitimate’.
