    I despise the maths element of Psychology... Never ask me about it. I shall cry...
    I think I should do a bit of reading about it soon... :rolleyes:

    But I'm not looking forward to it... :afraid:

    Maybe its the sign test i need?! I just know the lecture notes said 'lets review the binomial distribution'
    the later on suddenyl mentioned a sign test, but im sure I remember someone saying 'binomial sign test'... but i might have made it up!

    HELP ME!!!! AAAAAAAAAAAAAH!!!!! :eek:
    Hannah to the rescue! I just looked through my notes I made on the sign test and found under this - Binomial probability - other way to work out the signs. The really hard way.

    n x (n-x) x (n-x)
    p(X) = C P Q = N! / X! (N-X)! p q
    X

    Ok offically cannot type the forumula here.. Ill write it in paint! (the exclamation marks are factorials.. before everyone thinks ive gone mad.) Its pretty bad but hopefully you get the gist. N = No. of pairs, X majority (negative or positive) So if we have 10 pairs and 9 decreases (negatives), then binomial probability works out the prob of at least 9 of 10 being decreases if the null hypothesis is true. (We should have 5 pos/ 5 neg.) So the probability of getting 9 negatives out of 10 pairs given that the null is that we should have 5 pos and 5 neg. God hope that makes sense
