Definition
The mean is a way of finding the average of a set of numbers. It is calculated by dividing the sum of the numbers by the count.
Example
Find the mean of the following numbers: [4, 7, 10]

sum = 4 + 7 + 10 = 21

count = 3

mean = 21 / 3 = 7

Mathematical Definition

LaTeX: \overline{x} = (\frac{1}{n})\sum_{i=1}^{n}(x_{i})
Code
import numpy

values = [4, 7, 10]

mean = numpy.average(values)
print(mean)
Notes
There are other types of mean, this one is called the 'Arithmetic Mean'. It is also called the 'Mathematical Expectation' and the 'Average'.
