The coefficient of rank correlation from the following data is r=0.792.

Explanation:

  • Given data can be tabulated as follows:

         x          y          rank(x)          rank(y)           |Dxy|                |Dxy|^2

        48        13            3                  5.5                 2.5                  6.25

        33        13            5                  5.5                 0.5                  0.25

        40        24           4                   1                      3                    9

        9          6            10                   8.5                 1.5                  2.25

        16         15           8                    4                     4                   16

        16         4            8                   10                     2                   4

        65        20           1                    2                     1                    1

        24         9            6                   7                      1                    1

        16         6             8                   8.5                  0.5                0.25

        57        19            2                   3                       1                   1

-------------------------------------------------------------------------------------------------

                                                                                              \Sigma Dxy^2=41

  • Now the expression to compute the rank correlation is given by . . .

                             \rho=1-\frac{6\Sigma D_{xy}}{n(n^2-1)}

                             \rho=1-\frac{246}{990}

                              \rho=\textbf{0.792}

 Hence,  the coefficient of rank correlation from the following data is r=0.792.
