THE ARTMATIC MEAN HOW TO
THE ARTMATIC MEAN SERIES

There are two methods for computing the A.M : , x n represent the values of n observations, then arithmetic mean (A.M.) for n observations is: (direct method)

THE ARTMATIC MEAN SERIES

Question 5: Find the mean of the first five prime numbers.For a raw data, the arithmetic mean of a series of numbers is sum of all observations divided by the number of observations in the series. Therefore, the arithmetic mean of marks obtained is 45. Question 4: The marks obtained by Subham in terminal examinations are 50, 35, 40, 45, and 55 respectively. The observations are 2a+3, a+2, 3a+4 and 4a+5. Question 3: If the arithmetic mean of 2a+3, a+2, 3a+4, 4a+5 is a+2, find the value of a. Therefore, the value of missing observation is 2. Question 2: If the arithmetic means of 5 observations 6, 7, 5, x, 10 is 6. Find its arithmetic mean.Ī.M = Sum of all numbers/Total no. Question 1:The marks obtained in math by 4 students of the class are 10,12, 22, and 30. Its mathematical representation can be shown as-įor example, the arithmetic mean of the numbers 2, 3, 4, and 7 will be given by We can calculate the arithmetic mean by summing up all the numbers of the group and dividing the sum by the number of items. The formula of arithmetic mean is given by:

Whereas, as there are also some cases that give an absurd value which counts as a demerit. It can simply be understood as a single average value obtained by the calculation of entire data.Īrithmetic is useful in day-to-day calculation as it gives a definite value, as well as it is easy to calculate and understand as it is based on observations. It is a method to calculate central tendency. The symbol used for the arithmetic mean is ‘X’.

Carl Friedrich Gauss in 1801, provided the Fundamental principle of number theory.Īrithmetic mean is defined as the sum of all of the numbers of the group, when divided by the number of items present in it.Īrithmetic mean is simply also known as mean or average.

The 17th-century Indian mathematician Brahmagupta is the “father of arithmetic”.

It was initially used to find the sum and difference of objects as well as for monetization purposes. It is in use since the ancient times of human civilization. History of ArithmeticsĪrithmetics have the longest in the field of mathematics. Arithmetic is a branch of mathematics concern with numerals and their traditional operations.
