Question

Calculate rank correlation coefficient from data in Example 4 in Section 11.4

Answer 1

`rho=1-(6[SigmaD^(2)+(1)/(12)(m^(3)-m)+(1)/(12)(m^(3)-m)...])/(N(N^(2)-1))`
`=1-[(6[18+(1)/(12)(5^(3)-5)])/(5(5^(5)-1))]`
`=1-(6[18+(1)/(12)xx(125-5)])/(5xx24)=1-(6(18+10))/(120)`
`=1-(168)/(120)=1-1.04=-0.4`
