Quartile,3 (Excel2000)
The enclosed attatchment is a small macro that doesn't produce the results intended.
When it computes the Median the figures are correct. However, the Quartile numbers are a mystery.

Re: Quartile,3 (Excel2000)
I can't help with Excel formulas, but I wonder: why not post an XLS workbook with sample data to manipulate with the code?

Re: Quartile,3 (Excel2000)
1) You're formatting the results as whole numbers while the formulas may well return numbers with a fractional part.
2) It appears that you are trying to calculate running "aggregrates" of columns H and K. What's the point of calculating the 3rd quartile of 2 numbers?

Re: Quartile,3 (Excel2000)
Hans, enclosed a snippet of the worksheet.with additional columns to compute the medians and quartiles manually.
The median function is the same for both (code/manual). The quartile results are incorrect as you can see. The question is WHY??
Calculating the 3rd quartile of 2 numbers is just a starting point. the numbers lower in the column are the figures of interest

Re: Quartile,3 (Excel2000)
I don't understand your example. The macro you posted earlier produces formulas, not constant values. Could you attach an example that illustrates the use of the macro, not something you edited?

Re: Quartile,3 (Excel2000)
Hans, all the cells that have a formula i.e. =a1+a2 show a constant instead of the formula in the formular bar.This is true for the entire worksheet. I don't know how this happened. Is there a way to trace back and correct this ?

Re: Quartile,3 (Excel2000)
I have no idea what you have done. Do you have a backup copy of the workbook?

Re: Quartile,3 (Excel2000)
If this macro was run, would that have caused the problem:
Sub ConvertToValues()
With Range("A1").CurrentRegion
.Value = .Value
End With
End Sub

Re: Quartile,3 (Excel2000)
Yes, that macro converts ALL formulas in the region containing A1 to values.

Re: Quartile,3 (Excel2000)
I found that macro in my stack of stuff and maybe ran it. Is there a procedure that can nullify that code and restore the formulas?

Re: Quartile,3 (Excel2000)
No, the macro cannot be undone. Your only hope is a backup copy from before you ran the macro.

Re: Quartile,3 (Excel2000)
I can understand that, but no matter what workbook I open the formulas are converted.
Does that mean that the computer is formatted?

This has nothing to do with "the computer is formatted" as far as I know.
