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 - Lonehunter |

I guess to better explain what the IQR is; it is the third quartile minus the first quartile. so my question should be how do i find the different quartiles for a frequency distribution.
