How do you get a mean ?

The "mean" is the average of a list of numbers. All you have to do is get the sum of all the numbers, then divide by the number of digits.

We know that mean is also known as the average and at the same time, the most commonly used measurement of central tendency... By using this formula, you can get the mean of a certain sets easily...

[tex]Mean= \frac{\sum x}{N} \\ \\ \sum x\ means\ the\ summation\ of\ x...\\ \\ Example: \\ \\ set\ of\ 91\ ,\ 84,\ 75,\ 81,\ 80 \\ \\ The\ following\ numbers\ above\ are\ the\ value\ of\ x. \\ \\ Get\ the\ summation\ of\ all\ x. \\ \\ \\ 91 \\ 84 \\ +\ 75 \\ 81 \\ 80 \\ ----- \\ \boxed{411} [/tex]

[tex]Mean= \frac{411}{N} \\ \\ N= Number\ of\ x\ \\ \\ Mean= \frac{411}{5} \\ \\ \boxed{\boxed{Mean=82.2}} \\ \\ \\ Hope\ it\ Helps :) \\ Domini [/tex]
