Here is my data...

x 5 9 2 5 6 8 6 3

y 10 3 7 6 2 3 8 5

The spearmans rank correlation coefficiant is ment to equal 0.482

All i get is -0.619

If i square the difference and find the sum i get 136 though the answer book shows it to be 124.5 though i cannot understand why.

Thanks

You forgot to rank the data!
