Solution-:
We prepare the following table:
X | Y | X^2 | Y^2 | X*Y | |
1 | 2 | 1 | 4 | 2 | |
3 | 4 | 9 | 16 | 12 | |
5 | 6 | 25 | 36 | 30 | |
Total | 9 | 12 | 35 | 56 | 44 |
and
and
Therefore, Correlation= 1.000
OR
By using R-Software:
> x=c(1,3,5);x
[1] 1 3 5
> y=c(2,4,6);y
[1] 2 4 6
> r=cor(x,y);r
