Average [mean] calculation using Libre Office

About

In mathematics and statistics, average [also called the mean] is the sum of a list of numbers divided by the size of the list. "In other words it is the sum divided by the count." [1]

Example

Count:
Un-arranged values are: $ 2, 6, 1, 3, 3 $

Re-arranged values $ 1, 2, 3, 3, 6 = 15 $

step by step: 


1. rearrange values from least to greatest for example: $ 2, 6, 1, 3, 3 $

2. Add all values to calculate sum for example: $ 1 + 2 + 3 + 3 + 6 = 15 $

3. divide $ 12 / 4 $ [4 is the count]

4. average [mean] = $ 3 $
