Question

There are 8 sophomores on the academic team. At the last competition, they each took the math test. Their scores were 82%, 92%, 76%, 72%, 92%, 74%, 80% and 78%. What is the median math score of the sophomores?

Answer 1

Median would be 80.75 or 79

Answer 2

The answer is 79%

Explanation:

First we will write the numbers in order.

72, 74, 76, 78, 80, 82, 92, 92

When the given set of values have odd number of items, the median is the center number.

But here the data set is even,so we will find the average of the two center numbers, that are 78 and 80.

The average becomes:

`(78+80)/(2)=(158)/(2)=79`

Therefore, the answer is 79%
