What is a Mean?
In mathematics and statistics, the mean is a measure of central tendency, commonly known as the average. It represents the typical value in a set of numbers.
How to Calculate the Mean
To find the mean of a set of numbers:
- Add up all the values in the data set.
- Divide the total sum by the number of values.
Formula
Mean=Sum of all valuesNumber of values\text{Mean}=\frac{\text{Sum of all values}}{\text{Number of values}}Mean=Number of valuesSum of all values
Example
If you have the numbers: 4, 7, 10
- Sum: 4 + 7 + 10 = 21
- Number of values: 3
- Mean: 21 ÷ 3 = 7
So, the mean is 7. If you want, I can also explain other types of means such as median or mode!
