From the following data, compute the coefficient of correlation between X and Y series.

Summation of product of deviations of X and Y series from their respective arithmetic mean =41

Text Solution

Verified by Experts

We are given
`N=6,bar(X)=350,bar(Y)=138,sumx^(2)=19,sumy^(2)=94,sumxy=41`
`r=(sumxy)/(sqrt(sumx^(2)xxsumy^(2)))`
Substituting the values, we get
`r=(41)/(sqrt(19xx94))=(41)/(sqrt(1,786)=(41)/(sqrt(42.26)=0.97`
Coefficient of Correlation (r)=+0.97
