It's not really homework help but I am trying to refresh and re-awaken my rusty knowlege really by trying to set myself a few problems.

I have a program that attempts to predict the outcome of an event that can have 1 of 6 possible outcomes. I have run it against 6 samples getting the following results:

S1 28.9% Correct of 180 events
S2 27.6% of 98
S3 31.0% of 126
S4 22.1% of 145
S5 30.3% of 119
S6 23.7% of 131

Having forgotten all my A Level stuff - I don't know where to go from here to determine how relevant these results / how confident I can be etc. Any help appreciated. I need a push in the right direction.
Many thanks in advance.
