A Comment for Teaching Correlation Coefficient in Elementary Statistics Course
Oh, Myong-Sik;

Abstract
A effective teaching method on correlation coefficient for elementary level statistics course is discussed in this article. The well known inequalities, such as Theorem 368 of Hardy et al. (1952), are used for the interpretation of concept of covariance. An Excel example is provided for the illustration of concept of correlation coefficient.
