Basics of Statistical Notation

You will be introduced to a large number of formulas in this section on statistical concepts. These formulas use a relatively standardized notation to simplify the description of how a statistic should be computed. This section introduces the logic and basic concepts behind that notation. With each new formula, we will remind you what the notation means, but this section provides a head's up before we get to those formulas and provides a helpful summary in case you forget a notational concept.
