Concept:The median is the middle value of a data set when the data is arranged in order.
Explanation:First, arrange the given data in either ascending or descending order.
Then, identify the value that splits the ordered data into two equal halves.
For an odd number of items, the median is the middle item.
For an even number of items, the median is the average of the two middle items.
Thus, the median is obtained by finding the item that divides the ordered set into two equal parts.
Answer:D. Arrange the data in either ascending or descending order and find what item divides the set in two equal parts.
