"okay. what does a correlation coefficient tell us?" zoe asks the members of her psychology study group. "the strength of a relationship between two variables," answers yvonne. "the direction of the relationship between two variables," puts in will, "the strength and direction of the relationship between the variables" says hannah. who is correct?

Answer 1

This includes the strength and direction of both variables, this means the degree to which the variables are affected one over the other and which variable exerts an influence on the other.
