Using quiz grades what is the median ?

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.
