Mean is the average value of set of numbers. Usually the term mean is referred arithmetic mean but there are different types of mean are there in math. Different types of mean are arithmetic mean, arithmetic harmonic mean, geometric mean, geometric harmonic mean.
Formula:
Arithmetic mean = (a_1 + a_2 + a_3 +... + a_n) / n
Where 'n' is the total number of elements in set. In this article we will discuss about how to find the arithmetic mean using calculator.

Steps to find the arithmetic mean using calculator are:
Step 1: Enter all the numbers separated by comma ","
Step 2: Click the button 'calculate'
Step 3: Total numbers and result will display on the below text boxes
Example 1: Calculate the arithmetic mean of following ages of 10 players; 20, 30, 40, 78, 65, 98, 77, 79, 63, 64.
Solution:
Formula: (a_1 + a_2 + a_3 +... + a_n) / n
Here a1 = 20, a2 = 30… and a10 = 64, n = 10
Arithmetic Mean Calculator
= (20 + 30 + 40 + 78 + 65 + 98 + 77 + 79 + 63 + 64) / 10
= 614 / 10 = 61.4
Therefore arithmetic mean of 10 player's age is 61.4.
Example 2: Calculate the arithmetic mean of following marks of 10 girls; 75, 93, 26, 69, 49, 45, 39, 30, 47, 73.
Solution:
Formula: (a_1 + a_2 + a_3 +... + a_n) / n
Here a1 = 75, a2 = 93… and a10 = 73, n = 10
= (75 + 93 + 26 + 69 + 49 + 45 + 39 + 30 + 47 + 73) / 10
= 546 / 10 = 54.6
Therefore arithmetic mean of 10 girl's mark is 54.6.
Example 3: Calculate the arithmetic mean of following heights of 8 boys; 136, 149, 120, 133, 155, 163, 169, 172.
Solution:
Formula: (a_1 + a_2 + a_3 +... + a_n) / n
Here a1 = 136, a2 = 149… and a8 = 172, n = 10
= (136 + 149 + 120 + 133 + 155 + 163 + 169 + 172) / 8
= 1197 / 8 = 149.62
Therefore arithmetic mean of 8 boy's heights is 149.62.
Example 4: Calculate the arithmetic mean of following marks of 9 students; 39, 58, 97, 69, 79, 92, 49, 50, 72.
Solution:
Formula: (a_1 + a_2 + a_3 +... + a_n) / n
Here a1 = 39, a2 = 58… and a9 = 72, n = 9
= (39 + 58 + 97 + 69 + 79 + 92 + 49 + 50 + 72) / 9
= 605 / 9 = 67.22
Therefore arithmetic mean of 9 student's marks is 67.9.
I am planning to write more post on Probability Distribution Function Example and cbse syllabus of 9th class. Keep checking my blog.
