Explain the concept of ‘correlation does not imply causation” in the context of x being a random variable and x being fixed by the experimenter.
What will be an ideal response?
Ans: “Correlation does not imply causation” can be misleading if not properly understood. The caution that correlation does not imply causation applies to situations in x and y are random variables from dependent populations. The term random variable simply means that the scores of the variable result from random selection. It is possible choose random samples of y scores for values of x that have been fixed by an experimenter. In this case, it is possible to ascribe causality to the association between x and y.
