I want the actual Median...

There are calc functions to compute these things, but the layout of your table will of course influence the formulas. Here's a simple example that calculates the statistics for the second column - it uses the @I..@II range reference notation to get the numbers between the first and second separators and the @> (@>>, @>>>, etc.) notation to refer to the last (last minus one, last minus two, etc.) row: --8<---------------cut here---------------start------------->8--- * mean, median, stdev | i | x | |--------+-----------| | 1 | 3 | | 2 | 1 | | 3 | 1 | | 4 | 2 | | 5 | 1 | | 6 | 3 | | 7 | 4 | | 8 | 1 | | 9 | 1 | |--------+-----------| | mean | 1.8888889 | | median | 1 | | sdev | 1.1666667 | | sum | 17 | #+TBLFM: @>$2=vsum(@I..@II) :: @>>>>$2=vmean(@I..@II) :: @>>>$2=vmedian(@I..@II) :: @>>$2=vsdev(@I..@II) --8<---------------cut here---------------end--------------->8--- More details about such references are in the Org manual: (info "(org) References") More details about the calc functions are in the Calc manual: (info "(calc) Single-variable statistics") Nick ^ permalink raw reply [flat|nested] 4+ messages in thread
