9, 21, 7, 11, 13, 21, 5, 14, whats the range?

Hello there Angieevans425!
Your Question(s):

Whats the range?
My Answer(s):
First, we need to figure out what range is.  The range is The difference between the lowest and highest values.  So, we need to order the numbers from least to greatest.  So order the numbers as: 
5, 7, 9, 11, 13, 14, 21, 21.
Then subtract the lowest number from the biggest number:

So, 16 is your range!
Hope I helped,
