The Median of the Following Data : 0, 2, 2, 2, −3, 5, −1, 5, −3, 6, 6, 5, 6 is - Mathematics

MCQ

The median of the following data : 0, 2, 2, 2, −3, 5, −1, 5, −3, 6, 6, 5, 6 is

• 0

•  −1.5

• 2

• 3.5

Solution

The given data is 0, 2, 2, 2, -3, 5, -1, 5, 5, -3, 6, 6, 5 and 6.

Arranging the given data in ascending order, we have

-3, -3, -1, 0, 2, 2, 2, 5, 5, 5, 5, 6, 6, 6

Here, the number of observation n=14 , which is an even number.

Hence, the median is

((n/2)^(th) "observation" +(n/2+1)^(th) "observation" )/2

=((14/2)^(th) "observation"  +(14/2+1)^(th) "observation" )/2

=(7^(th) "observation " +8^(th)"observation ")/2

=(2+5)/2

=7/2

=3.5

Is there an error in this question or solution?
