Q E b AA Correlation Coefficient Another measure related to the coefficient of determination is the coefficient of correlation D. This measure also expresses the degree or strength of the linear relationship. It is usually expressed as r and can be any number between and including +1 and -1. Figure 4.3 0 illustrates possible scatter diagrams for different values of r. The value of ris the square root of r. It is negative if the slope is negative, and it is positive if the slope is positive. Thus, The correlation coefficient ranges from - 1 to +1. (4-11) r = ±V r² For the Triple A Construction example with r = 0.6944, 53 r = v0.6944 0.8333 11 116 /579 em 3.pdf Problem 1 Excel.pdf Problem 1 Excel.pdf Ex. Credit Prob 1..pdf Ex.
