What is the median of the following group of numbers? 14 12 20 22 14 16
a. 12
b. 14
c. 15
d. 16
Answer: c. 15
The median of a group of numbers is
found by arranging the numbers in ascending
or descending order, and then finding the
number in the middle of the set. First arrange
the numbers in order: 12 14 14 16 20 22.
Since there is an even number of numbers in
the list, find the average of the two numbers
that share the middle. In this case the numbers
in the middle are 14 and 16, and the average
between them is 15.
