Stat171, ilearn videos? (1 Viewer)

[mike24]

Hey!!! Kind of paranoid about Stat171 and taking it soon was wondering if i could borrow anyone who has taken it's account to download some of the lectures notes and lecture videos to see what it's like. Please would be really helpful, just pm me =)

(I assume you doing actuarial studies, otherwise you should take stat170!)

You don't need to worry about this subject pretty much, it is quite easy.

It is just introduction of statistic where you need to know how to apply the statistical tests without knowing the proofs. (you learn the hardcore proofs in stat272/271 and it is not a core subject unless you doing actuarial studies.)

And you can bring 2 A4 pages in the final exam so you don't even need to memorize those formulas for final.

Unless you really really worry about this subject, otherwise just relax

Oh cool i just wanted to see the lecture notes and the little videos they give you to have a better idea of what they want so i don't get too shocked since i hear sooo many bad thing. It's nice that you you get to bring a cheat sheet, oh ok could you list the main topics i wanted to look 'em up they seem really hard. Is the text book used at all? How different is it to the other stat course?

I bought the textbook and never use it at all.

First topic just revision of high school stat such as the charts, mean, median, mode, standard deviation..etc
Then you start to learn some simple probability with perms and combination and Bayess theorem.
Third and Forth topics are random variable (Discrete and Continues) where you need some basic calculus.
Fifth topic is sampling distribution where you use normal distribution to approximate other distribution from the central limit theorem.
Topic 6-9 are the significant tests where you test the mean with known/unknown variance.

Then you learn regression and odds.

Don't be scare, you just need to know which formula to use for the tests, you don't even need to know how it works. ( you learn the derivation in 2nd yr stat if you take 272/271)
Like 2 sided test with unknown variance you use the t-test and t-table

All you need is good comprehensive skill (so you know which formula to use)
and good at simple algebra and calculus.

Better focus on first year maths if you enroll math132/133, you need to be good at them for later stat or acst unit.

What bad things you heard? This course is so easy compare to other courses I took lol
