Goodness of fit questions

Expected Actual %bias/RE
50 52.7 5.4
50 47.7 -4.6
100 98.5 -1.5
300 291 -3
600 651 8.5
1000 946 -5.4
2000 1940 -3
3000 3170 5.7
5000 4970 -0.6
6000 5960 -0.7
7000 7450 6.4
9000 9110 1.2
10000 10000 0
10000 9150 -8.5

I have this data and have to work out the GOF (which I know is 4.96!) using this equation: GOF=SQRT((sum of RE^2)/n-1))

Everytime I try to work it out my answer is way off? what am I missing ?
