Statistics is a very powerful topic that is used on a daily basis in
many situations. For example, you may be interested in the age of the
men who attend Silver’s Gym. You could not assume that all men are the
same age. Thus, it would be an inaccurate measure to state that “the
average age of men who attend Silver’s Gym is the same age as me.”
Averages are only one type of statistical measurements that may be of
interest. For example, your company likes to gauge sales during a
certain time of year and to keep costs low to a point that the business
is making money. These various statistical measurements are important in
the world of statistics because they help you make general conclusions
about a given population or sample.
