WebThe correct answer is (e) X and Y medium correlation, and if X increases, Y will generally decrease. A Pearson correlation coefficient of -0.54 indicates a moderate negative correlation between the two variables X and Y. This means that as the value of X increases, the value of Y tends to decrease, but not necessarily in a perfectly linear or predictable way. http://xmpp.3m.com/research+question+for+pearson+correlation
