One way of obtaining the median of a given data is to__________
- Sum the value and divide by the number of items.
- Arrange the data in ascending order and subtract each item from the mean.
- Arrange the data in descending order and add each item to the least.
-
Arrange the data in either ascending or descending order and find what item divides the set in two equal parts.
The correct answer is: D
Explanation
To find the median, first order the numbers from smallest to largest. Then find the middle number. For example, the middle for this set of numbers is 5, because 5 is right in the middle: 1, 2, 3, 5, 6, 7, 9.
