What is the median of the following salary list $32,019, $21,971, $27,512, $43,702, $38,860, $25,997
mylen [45]

Answer:

$29765.50

Step-by-step explanation:

Median is the middlemost value (or the average of the 2 middlemost value if there are even number of values) in an ascending order.

First, arrange the salary list in an ascending order.

$21,971 , $25,997 , $27,512 , $32,019 , $38,860 , $43,702

As we can see here, there are even number of values (6), so the median will be the average of the 2 middlemost value, which will be:

Median = \frac{27512 + 32019}{2}

= \frac{59531}{2}

= $29765.50
