554             1
957             1

Just some background what does above information means-

1702 calls came back in 0 milliseconds
15036 calls came back in 1 milliseconds
14262 calls came back in 2 milliseconds
etc etc

So to calculate the 95th percentile from the above data, I am using this formula in excel 2010-

=PERCENTILE.EXC(IF(TRANSPOSE(ROW(INDIRECT("1:"&MAX(H$2:H$96))))<=H$2:H$96,A$2:A$96),0.95)

Can anyone help me whether the way I am doing in Excel 2010 is right or not?

I am getting 95th percentile as 10 by using the above scenario.

Thanks for the help.

Answer 1

that's essentially the same question you asked here and the formula I suggested. As per my last comments in that question - that formula should work OK as long as you use CTRL+SHIFT+ENTER correctly. I get 10 as the answer for this example using that formula.

I think you can verify manually that that is indeed the correct answer. If you have a running total in an adjacent column then you can see where the 95th percentile is reached......
