Some have argued that the correlation coefficient is meaningless in a regression analysis, since it depends, in large part, on the fixed particular values of X obtained in the sample and the probability distribution of X in the sample (see Cohen & Cohen, 1975, p. 5).

Linear Correlation and Regression. In this lecture, we’ll be looking at scatter plots and inferences you can make about them. There are two topics here: correlation, which deals with describing the relationship between two variables and deciding about its strength, and regression, which involves using values of one variable to make predictions about the values of the other variable.
