Does anyone know how to find the Five-Number summary of a set of numbers?
These are the numbers.
7,7,5,4,1,9,8,8,8,5,2
arrange in order
1 2 4 5 5 7 7 8 8 8 9
Upper Extreme = biggest one = 9
Lower extreme = smallest one = 1
median = half bigger, half smaller = the first 7
Lower quartile = median of numbers left of median = 4
Upper quartile = median of numbers right of median = 8
