Question

What is the median salary of an employee? If the frequency table represents the number of employees and their salaries.

Salary	$1000$	$500$	$1500$	$2000$	$3500$
Frequency	$2$	$1$	$5$	$7$	$2$

• A. $1000$
• B. $1500$
• C. $500$
• D. $2000$

Answer 1

The correct option is D $2000$

Salary	Frequency	position
$1000$	$2$	$2$
$500$	$1$	$3$
$1500$	$5$	$8$
$2000$	$7$	$15$
$3500$	$2$	$17$

Sum of frequency $=2+1+5+7+2=17\left(odd\right)$

So Median is at $\left(\frac{n+1}{2}\right)=\left(\frac{17+1}{2}\right)=9$

$9th$ position comes after $8th$ but before $15th$ position

$Median=2000$
