## Understanding Mathematical Symbols – Summation (Addition)

When a summation over a range of numbers is to be presented it is not uncommon to shorthand the notation using the Sigma (the letter S in Greek, written as a Big E with the middle t replaced by a less than symbol ). For example, the following sums can be represented in the Sigma … Continue reading Understanding Mathematical Symbols – Summation (Addition)

## Arithmetic Mean

Arithmetic Mean is one of the most common ways of calculating a sample’s average. The method of calculating the Arithmetic Mean is to sum the values in the sample set and divide the result by the sample size. In Mathematical Notation this is written as: The mathematical formula above with the sample examples can be … Continue reading Arithmetic Mean
