lol my graphix calculator served me no purpose in S2 whatso ever!

It will however help you in calculating regression lines...but you've got to show your working when doing that anyway :s
3. Can save time in looking things up in tables for poison and binomial distribution questions. And handy for checking for silly errors in normal distribution questions (I make lots of those )

Also the numeric integration is useful for checking things in cdf questions.

For the normal distribution, go to run then press OPTN then F6 until you get around to PROB (over F3). Press F3 then F6 again until you get P(, Q(, R( and t(.

P( gives the probability that your variable is equal to or less than X standard deviations from the mean (so P(0)=P(X<0), P(-1)=P(X<-1) and so on).
R( gives the probability that your variable is equal to or greater than X standard deviations from the mean (so R(1)=P(X>1)).
Q( gives the probability that your variable is between 0 and X standard variations from the mean (so Q(1)=P(0<X<1) and Q(-1)=P(-1<X<0)
I haven't figured out what t( does.
