The arithmetic mean is the average obtained by dividing the totals of a group of data by the total number. It is expressed as the average of the numbers in the series.

Let the elements of a series with n elements be x _{ 1 }, x _{ 2 }, x _{ 3 } ... and x _{ n }. For the arithmetic average calculation of this series;

Arithmetic Mean = (x _{ 1 } + x _{ 2 } + x _{ 3 } + ... + x _{ n ) / n.}

For example, the scores of students in a class are as follows.

• Student 1 score: 55,

• Student's score: 75,

• 3rd student's score: 80,

• 4th student's score: 100,

• 5th student's score: 70,

• 6th student's score: 90,

• 7th student's score: 80,

So how do we calculate the arithmetic average of students' scores?

Since the arithmetic average calculation formula is the sum / number of the numbers in the series;

(55 + 75 + 80 + 100 + 70 + 90 + 80) / 7 = 78.57.
