What is arithmetic mean example class 11?

An example of calculating the arithmetic mean for class 11 involves finding the average of a set of numbers.

Arithmetic Mean Example

Here's an example appropriate for a class 11 level understanding:

Problem: Find the arithmetic mean of the first five prime numbers.

Solution:

1. Identify the first five prime numbers: 2, 3, 5, 7, and 11.

2. Apply the arithmetic mean formula:

   Arithmetic Mean = (Sum of all observations) / (Total number of observations)

3. Calculate the sum: 2 + 3 + 5 + 7 + 11 = 28

4. Divide by the total number of observations: 28 / 5 = 5.6

Therefore, the arithmetic mean of the first five prime numbers is 5.6.

This example demonstrates a simple calculation of the arithmetic mean using prime numbers, a topic typically covered in class 11 mathematics. The concept extends to finding the average of any set of numerical data, often used in statistics and data analysis.
