# Mean

Mean, abbreviated as m, is the average value for a group of data or the sum of all the values divided by the number of values.

## Mean formulas

\(\large{ m = \frac{ high \;-\; low }{ 2 } }\) | |

\(\large{ m = \frac{ \sum X_s }{ n } }\) |

### Where:

\(\large{ m }\) = mean

\(\large{ \sum X_s }\) (Greek symbol Sigma) = sum of data values \(\large{ X_1, X_2, X_3, ... }\)

\(\large{ n }\) = number of data values
