Answer:
Correlation and causation are two very different things
Explanation:
Correlation means that two or more factors are dependent on each other in a way that one can be predicted with the help of the other. On the other hand, causation means that one thing causes another. For instance, a correlation between ice cream consumption and hot weather means that when its hot people eat ice cream more and in less hot weather people eat less ice cream. But if this correlation is confused with causation between ice cream demand and hot weather then it would mean that eating ice cream causes hot weather which will not be correct. Also for causation, three criteria should be met which are correlation, no effect of third extraneous variable and this casual effect should precede all other rational effects.
