Mean
The formula for the mean of a set of \( n\) values \( x_1, x_2, ..., x_n \) is:
$$ \mu= \frac{1}{n} \sum_{i=1}^{n} x_i $$In this formula, \( \mu \) represents the mean or average of the values, which is calculated by adding up all the values and then dividing the total by the number of values \(n\).
Example
Suppose we have a set of numbers: {2, 4, 6, 8, 10}. We can find the mean by adding up all the numbers and dividing by the total count:
\begin{equation} \mu = \frac{2+4+6+8+10}{5} = 6 \end{equation}In this example, the mean, denoted by the symbol \( \mu \), is equal to 6.
