MEDIAN :
the number in the middle
40, 49, 27, 12, 25, 68, 30
Write numbers in rank order:
12, 25, 27, 30, 40, 49, 68
Find the score in the middle:
12, 25, 27 __ 30 __ 40, 49, 68
Median = 30
What if even number of numbers in sequence?
Mid point is half way between 27 and 30
30 - 27 = 3 --> 3 / 2 = 1.5
--> 27 + 1.5 = 28.5 Median = 28.5
