Say you predicted that Brazil would have beaten Germany 2-1, by how large a percentage were you wrong?
As Brazil scored 1 out of 2 goals, you could say that part of your prediction was 50% right. However, as Germany scored 7 times the number of goals, that's less accurate. On top of this, the combination of the two scores has me perplexed and any help would be much appreciated.
To summarise, how accurate is your prediction given the following:
Predicted Score: Brazil 2-1 Germany Actual Score: Brazil 1-7 Germany
