Given :

The first 20 natural numbers

To find :

The range of first 20 natural numbers

Solution :

Step 1 of 3 :

Write down the given data set

We are given first 20 natural numbers

Now first 20 natural numbers are 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20

Step 2 of 3 :

Find maximum value and minimum value

Maximum value = 20

Minimum value = 1

Step 3 of 3 :

Find range of the data set

We know that for a given set of observations range is defined as the difference between maximum value and minimum value of the observations

So the required range of the data set

= Maximum value - Minimum value

= 20 - 1

= 19

Hence range of first 20 natural numbers is 19
