I just took an online quiz with 10 football questions on an expert level. Each question had 4 possible answers. I got 1 (one) question out of ten right.
That was somewhat depressing - not because I fancy myself a football expert, the questions really were much too hard for my level of knowledge. But I think I did a good deal worse than I would have usually done by chance alone.
Can anyone here calculate what the p-value is for getting one out of ten right if the null hypothesis is that this quiz is ruled by chance alone?
Just out of interest, if anyone feels up to it AND sufficiently interested.
