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]
