What is median of 85 91 48 98 99 91 90 84 91?

85 91 48 98 99 91 90 84 91

To find the median, first rearrange the numbers in rank order. That is from lowest to highest.

Hence

48,84,85,90,91,91,91,98,99.

Next we notice that there are nine terms.

To find the median we than take the absolute middle term. In this case it is '91'. There are four terms to the left and right of the median term.

NB If you had left the numbers in the original order, the median would have been '99', which is incorrect.

NNB As an aside the MODE is also '91'. However, in this case it is found by looking for the term that occurs most frequently. In this case there are three lots of '91' , but only one of each other term.

Hope that helps !!!!
