Im currently doing an introductory stats course and have learnt:(adsbygoogle = window.adsbygoogle || []).push({});

- poisson distribution

- binomial distribution

- normal distribution

- t-student

- and chi-square

I think I know what most of them look like but am having a bit of a hard time distinguishing what distribution to use when faced with questions.

Heres my current understanding:

- poisson distribution - when pop mean is given over an interval?

- binomial distribution - when given sample size and p of success

- normal distribution - n >30 or if normal

- t-student - when population is normal distributed but variance parameter is unknown

- and chi-square - not too sure when to use.

Wondering if anyone can help me with my current problems, thanks in advance!
