Stats 2 is about inference — what you are entitled to conclude about a population from a sample. The calculations are mechanical once the framing is right, so the subject rewards understanding what a test is claiming over memorising formulas.
Where marks go: Answers lose marks for stating a conclusion the test does not support — be precise about the null hypothesis and about what rejecting it actually means.
Nine documents in this collection: one formula sheet, one handwritten set, two reference books, four week-wise note sets and one study document.
