12.5: Testing the Significance of the Correlation Coefficient

WebThere are two straightforward ways to determine if there is a correlation between two variables, X and Y. One is simply to construct a scatter diagram. In a scatter diagram, paired values of X and Y are plotted. The scatter diagram will show a picture of the correlation. You can see if the correlation is positive, negative or non-existent.
