The graph below represents the number of siblings each student in a class has.

Given;
There are given that the graph represents the number of siblings.
Explanation:
According to the given graph:
The frequency of the number of siblings is:
[tex]6,7,4,4,3,2[/tex]Now,
We need to find the value of the range:
So,
From the concept of range:
The value of the difference between the highest data and lowest data will be representing the value of the range:
So,
The highest number is 7 and the lowest data is 2:
So,
[tex]\begin{gathered} Range=7-2 \\ =5 \end{gathered}[/tex]Final answer:
Hence, the value of the range is 5.
