Question

How do you find the average of one number?

Answer 1

Hint: The average of a set of numbers is simply the sum of the numbers divided by the total number of values in the set, which is given by the formula,
Average of numbers\[ = \dfrac{{{\text{Sum of numbers}}}}{{{\text{total number of numbers}}}}\].

Complete step-by-step solution:
The mean value which is equal to the ratio of the sum of the number of a set of given values to the total number of values present in the set is known as average.
Average of a set of numbers is calculated by finding the sum of the numbers divided by the total number of numbers, formula used to calculate average is given by,
Average of numbers\[ = \dfrac{{{\text{Sum of numbers}}}}{{{\text{total number of numbers}}}}\].
For example: If we want to find the average of 5 numbers i.e., 2, 7, 5, 10, 6, first we know that the total number of numbers are 5, and then we will find the sum of the numbers given and substitute in the formula,
So, sum of the numbers given = \[2 + 7 + 5 + 10 + 6 = 30\],
Total number of numbers= 5,
Using average formula,
Average of numbers\[ = \dfrac{{{\text{Sum of numbers}}}}{{{\text{total number of numbers}}}}\].
Average of numbers\[ = \dfrac{{30}}{5} = 6\].
Now here, we have to find the average of one number,
Let us consider as\[n\],
Here total number of numbers = 1,
And sum of the numbers =\[n\],
Now using the formula,
Average of numbers\[ = \dfrac{{{\text{Sum of numbers}}}}{{{\text{total number of numbers}}}}\],
Now substituting the values we get,
Average of numbers\[ = \dfrac{n}{{\text{1}}} = n\].
Average of one number is always the number itself, as the average is the sum of the numbers divided by their count. As there is only one number this calculation is always the number itself.

\[\therefore \]The average of one number will be the number itself.

Note: The term average is generally used in everyday life to express an amount that is logical for a group of people or a group of things, Averages are used because they help us to summarize a large amount of data into a single variable, and indicates some variability around any single value within the original data.
