I had a hard time understanding how you interpret the differences between samples Or at least understanding how to do so outside of the examples given.

On the questions at the end, when you ask us to calculate the standard deviation, you don't specify whether it is sample or population. If I am just given a small set of numbers, rather than told I have a sample drawn from a larger population, shouldn't I assume that that set is the complete set, and therefore use population SD?
