Percentile Analysis Across 2 Columns
I'm wanting to calculate decile (or equivalent percentile) salaries to see
if there is any difference between 2 departments (A and B). So dummy data looks like : Dept Salary A £52,670 A £53,530 A £56,117 B £41,437 A £51,809 B £53,530 A £32,803 B £52,670 B £35,398 A £52,670 B £31,077 A £35,398 A £23,831 B £17,100 B £15,929 A £19,602 A £16,688 B £16,307 B £16,688 B £14,065 Range names, which cover about 2000 rows of actual data are used "Dept" and "Salary" Can SKS help out Thanks, Rob |

Percentile Analysis Across 2 Columns
Hi,
You could use 2 helper columns to seperate Dep'ts A & B In column C =IF(A1="A",B1,"") and in column D =IF(A1="B",B1,"") The use percentile on these 2 columns =PERCENTILE(C1:C20,0.1) =PERCENTILE(D1:D20,0.1) Mike Mike "BRob" wrote: I'm wanting to calculate decile (or equivalent percentile) salaries to see if there is any difference between 2 departments (A and B).

Tx but I'd simplified the example a bit too much :(
There are about 60 different depts on the live data so, to keep things manageable, I really need to get it done in a single step. "Mike H" wrote in message ...

Hi,
To do it in the same column requires an array formula. I've used the department name "A" in this formula but you could create a list of department in a column allowing you to drag the formula down. The example formula gives the 10th percentile so for the 20th change to 0.2 =PERCENTILE(IF(A1:A20="A",B1:B20,FALSE),0.01) Remember this is an array so commit with CTRL+Shift+Enter and Excel will put curly brackets around it {} if you do it correctly Mike "BRob" wrote: Tx but I'd simplified the example a bit too much :( There are about 60 different depts on the live data so, to keep things manageable, I really need to get it done in a single step.

Typo,
For the 10th percentile it's 0.1 not 0.01 as in the formula "Mike H" wrote: Hi, To do it in the same column requires an array formula.
