Finished with the module, now just have to do a few papers every couple of weeks to keep it in my head.
I've also finished it. Least favourite part is hypothesis testing - not that it's the hardest bit, it's just really boring.
I'm not sure if it's my last. Both FP3 and S2 are meant to be sat in the morning on the 22nd, so not sure which one's going first...
Nah, i only go as far as FP2, plus im not a fan of statistics anyway, just to do further maths i need to do stats -.- also M3 happens to be my first exam aswell?? who makes these timetables?!
I'm pretty much self-teaching it so not expecting a great result
Haha, well i was debating to do FP3, because if i had done i would not need to do S2, but i thought nahhh, FP2 is gonna be enough. I dont actually mind FP2 tbh, its quite interesting, but going FP3 might jsut have been abit too far, and as you say, if FP3 and S2 clash, i would die.
Probably the non-uniform probability density functions and cumulative frequency functions are the most mathematically demanding of all the topics, but that isn't saying much
When you are doing hypothesis testing with discrete distributions such as Binomial and Poisson, the cumulative probability goes up in jumps. Although you may wish to do a 5% test (nominal) you will actually have to do something near by such as 4.85% (actual).
One more question, is the probability of rejecting the null hypothesis and the probability of incorrectly rejecting the null hypothesis is same value?
