Question

The data is given below:


We can make bins of interval length $5$.

• A. $5$
• B. $4$
• C. $3$
• D. $6$

Answer 1

The correct option is D $6$

Concept:
We divide the range by width of class interval to find the number of bins.


The range of the given data is $55-25.5=29.5$.

In order to break the data ($25$ to $55$) into bins of equal interval lengths, we can take the interval length of $5$ units as one of the suitable options.

On dividing the range by the interval length, we get
$\frac{29.5}{5}=5.9\approx 6$

So, we can take $6$ bins of interval length of $5$ units to break the data ($25-55$) into bins of equal interval lengths.
