what is the median of a data set is alwayssometimesnever one

Solution

SOMETIMES. [ANSWER]

***************************

This is an example where the median is one of the data points:

{1,2,3}

In this data set, Median = 2, which is in the data set.

This is an example where the median is not one of the data points:

{1,2,3,4}

In this data set, the median is the average of the middle two values,

Median = (2+3)/2 = 2.5,

which is NOT in the data set.
