Question

From the table, find the median class for the following data.

• A. $13.5-16.5$
• B. $12.5-13.5$
• C. $10.5-14.5$
• D. $12.5-10.5$

Answer 1

The correct option is A $13.5-16.5$

To find the median class:
First add the total number of frequencies.
Here, $f=20$
$=$ $\frac{Totalnumberoffrequency}{2}$
$=$ $\frac{20}{2}=10$
$\text{from c.f column we can see 12 is greater than and nearest to 10}$
Hence, the median class of $10$ lies between the intervals $13.5-16.5$.
