I'm referring to the hsc 2 unit math we do right now. like the whole integration, differentiation, calculus stuff. I know that statistics is covered in med sci but it does not involve any of the calculus topics, right?
The techniques of statistics are based on the theory of probability and associated distribution functions. The more theoretical study of statistics is called Mathematical Statistics and involves advanced calculus (measure theory. sigma-algebra, stochastic processes, etc), matrices etc. Often those wanting to apply statistical techniques for the agricultural and social sciences may use the various statistical techniques (regression analysis, analysis of variance, significance tests, experimental design etc etc) without studying the theoretical bases of the subject - as this requires a strong maths background (certainly way beyond NSW HSC 2 unit Advanced)
Anyway - whenever possible it is handy for university courses to have at least 2U Advanced as a minimum, in case you need some maths background for your chosen course.
