计算列中一系列类别的中位数-Excel

Question

So in our experiment we took several samples from a number of fields. In each of these areas we counted the number of clover plants and their sizes. So each row of the table is one sample with how many size1, size2 (etc) plants appeared in that sample. So I want to know whether there is a code that I can put into column G that will work out what the median size class is.

For example, Column G would show 'size1' for Row 7, because it is the middle value if the data were lined up (size1, size1, size1, size2,size4).

Again I'm sorry if I'm making a total pig's ear of this. Stats seems to be very good at stumping me at the simplest things.

If you're trying to return the column header from the column that has a non-zero number, you can use this in G2 , and drag down:

=INDEX($B$1:$F$1,SUMPRODUCT(MAX(($B2:$F2<>0)*(COLUMN($B2:$F2))))-COLUMN($B$1)+1)

Note you can wrap that in IFERROR([formula], "") to hide the error that occurs if there's not a cell that's not equal to 0 .
