Using the data set below, please calculate the:
9 7.5 15 7.5 9
-----
Put the data in ascending order: 7.5,7.5,9,9,15
-------------------
- Range = max-min = 15-7.5 = 7.5
------------------------------------------
- What would be the percentile rank of the number 9?
Count the number of data elements below 9: 2
Change to %: 2/5 = 0.40
9 is at the 40%ile
