Calculate Spearman's rank correlation coefficient

Text Solution

Verified by Experts


`r_(k)=1-(sumD^(2))/(N^(3)-N)`
Here, `N=10,sumD^(2)=100`
Susbstituting the values, we get
`r_(k)=1-(6xx100)/(10^(3)-10)`
`=1-(600)/(1,000-10)`
`=1-(600)/(900)`
`=1-0.606`
`= 0.394`
Coefficient of Rank Correlation `(r_(k))=0.394`
