Question 3

Correct Answer:

Verified

A correlation is not sufficient evidence to support a causal statement.The coefficient summarizes the degree to which scores on two variables "go together." That scores on two variables are correlated does not mean one variable causes the other.One possibility is that a third variable is causally related to both variables.
