1. If it said calculate the sample mean and variance, and I just put the numbers in my calculator and used the functions that give the answer, w/o working out would i get the full marks?
2. Well ck the mark schemes previously as the scheme says what to give if only an answer is given.
Sometimes you have M1A1 for working and answer and just B1 for answer only. There is no hard and fast rule. Since your calculator also gives your stuff like sigma x sigma f(x) etc. You should be able to do the working and answer pretty quick since you have to enter the data anyway.

M1 = method mark
A1 = accuracy mark
B1 = independent mark
