What is the Median?
The median is defined as the middle number in a list of numbers that has been sorted, either ascending or descending, and which may be more representative of the data set than the average. It is the point above and below which half (50%) the observed data falls, and so represents the midpoint of the data.
Median = (N₁ + N₂)/2
Given data as :
Math score of the sophomores were
82%, 92%, 76%, 72%, 92%, 74%, 80%, and 78%.
To determine the median, we need to arrange the numbers in ascending order.
72%, 74%, 76%, 78%, 80%, 82%, 92%, 92%
The two middle numbers are 78 and 80 since its even there is no true middle number
78, 80,
Since there are two middle numbers then you add them together and then divide by 2.
Median = (78+80)/2
Median = (158)/2
Median = 79
Hence, the median math score of the sophomores was 79%.
