Answer:
The median is a value in the middle of an ordered set of numbers.
Step-by-step explanation:
Example: given the scores 78, 65, 100, 80, 92
You put the numbers in order first: 65, 78, 80, 92, 100
There are 5 numbers in the list, so the middle one is 80. The median is 80. (Helpful hint: think of the median of a highway--it's right in the middle of the road.)
What happens if there is an even number of numbers? You create a "middle" number by averaging the two nearest the middle.
Example: given scores 62, 50, 100, 94
Sort them in order: 50, 62, 94, 100
The two numbers nearest the middle are 62 and 94. Average them to get (62 + 94) / 2 = 156 / 2 = 78 . The median is 78.
By the way, to find the mean, add the numbers up and divide by how many there are.
