\LARGE \overline{x}=\frac{x¹+x²+x³+...+x^n}{N}
Arithmetic Mean= Sum of all Observations/Total Number of Observations
Example:
There are five observations. These are 10, 20, 30, 40, 50. Find their arithmetic mean.
Solution:
\LARGE \overline{x}=\frac{10+20+30+40+50}{5}
\LARGE =\frac{150}{5}={30}
Answer: 30
