Question

How do you find the mean?

Answer 1

The mean of a set of numbers can be found by dividing the sum of numbers by the number of numbers in the set.

Let $x_1,x_{2,}{x}_3,...x_n$ be the observations. the mean of this $n$ observations is given by:

Mean$\mathbf{=}\frac{{\mathbf{x}}_{\mathbf{1}}\mathbf{+}{\mathbf{x}}_{\mathbf{2}}\mathbf{+}{\mathbf{x}}_{\mathbf{3}}\mathbf{+}\mathbf{\dots }\mathbf{+}\mathbf{}{\mathbf{x}}_{\mathbf{n}}\mathbf{}}{\mathbf{n}}$

Hence, above shown is the formula formula for mean.
