ABSTRACT
One aspect of probability and statistics concentrates on accurately summarising and
describing patterns in an individual data sample. Another more common aspect is
to use a data sample to make general inferences about the underlying population it
has been taken from. For example, a group of university students might be surveyed
about the amount and type of beer they consume on a weekly basis. The aim of this
study might be to infer results about the student body as a whole; for example,
whether some types of students drink more than others or whether university
students consider brand X beer to be trendy. These inferences might be useful to a
brewery that wants to improve flagging sales of brand X beer.
