Question

Identify the median class.

X	$5-9$	$9-13$	$13-17$	$17-21$
F	$3$	$8$	$9$	$4$

• A. $5-9$
• B. $9-13$
• C. $13-17$
• D. $17-21$

Answer 1

The correct option is C $13-17$

To find the median class$:$

First add the total number of frequencies.

Here, $f=24$

$=\frac{\left(Totalnumberoffrequency\right)}{2}$

$=\frac{\left(24\right)}{2}=12$

Hence, the value 12 lies in the class interval 13-17 from the cummulative frequency table.
