IQR of a frequency
Hello,
This is my 1st time posting on this forum so please excuse any lack of information.
I am trying to write a template for finding descriptive stats for grouped data. i have 9 total stat formulas written and i cannot get this one or find it anywhere.
The stat i need is Interquartile range. i can easily do it for a normal set of data, but for a frequency data set i cannot get any known formula to work.
for instance this data:
0 10
1 15
2 27
3 18
4 38
5 57
6 22
7 5
8 2
9 3
10 0
what would the formula be?
Thank you in advance for any help
