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."

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] = $3$
