Question

Year 2015 2016 2017 2018 2019 2020 2021
The graph shows the number of members of the Math Club from the years 2015 to 2021. Find the range.

Answer 1

To find the range of the number of members from 2015 to 2021, you subtract the smallest number of members from the largest number of members.

From the data provided:

• The number of members over the years is: 22, 25, 36, 30, 32, 28, and 30.

1. Identify the smallest number: 22 (in 2015)
2. Identify the largest number: 36 (in 2017)

Now, calculate the range:

\[ \text{Range} = \text{Largest number} - \text{Smallest number} = 36 - 22 = 14 \]

Therefore, the range of the number of members is 14.
