The data below represents students’ test scores. Which of the following is the median of the set data? 80, 76, 92, 96, 44, 86, 56, 93, 69
A. 86
B. 69
C. 44
D. 80
Explanation: the median of a data set is the element that is found on the middle position.
To find median, organize the given data from the smallest to largest.
44, 56, 69, 76, 80, 86, 92, 93, 96
Now, the number of elements in the date set is 9, which is an odd number. The median falls in the position
(N+1)/2=(9+1)/2=10/2=5.
The number that falls in the 5th position is 80. Thus, 80 is the median of the data.
Therefore, the Correct Answer is D.
