Given;

There are given that the graph represents the number of siblings.

Step-by-step explanation:

According to the given graph:

The frequency of the number of siblings is:

`6,7,4,4,3,2`

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,

`\begin{gathered} Range=7-2 \\ =5 \end{gathered}`

Final answer:

Hence, the value of the range is 5.
