averaging values according to (very) complex conditions
Please help! There must be a way to make excel do this:
I'm trying to compute a formula to average values only if they mee certain criteria. I am working on outputs generated by Superlab Pro. The data are from a experiment where trials are randomised. I need Excel to average all values from, say column A providing tha they correspond to condition x in column B (so average all the value which are in a row that contains the term x in column B) , AN condition y in column C AND condition z in column D. The key problem is that I can't know in advance which rows will contai the term x, y or z, so I wonder if there is a way to specify "any o the rows which contain a specific term" or something similar.... I would be extrememly grateful for any advice. This would make my lif so much easier. Thanks, Lior -- Message posted from http://www.ExcelForum.com |

=SUMPRODUCT((A1:A100)*(B1:B100="myValue"))/COUNTIF(B1:B100,"myValue")

For only one condition, Faster would be:
=Sumif(B1:B100,"myValue",A1:A100)/COUNTIF(B1:B100,"myValue") -- Regards, Tom Ogilvy "liory " wrote in message ... Please help!

Try the array formula:
=SUMPRODUCT(A1:A10,((B1:B10="x")*(C1:C10="y")*(D1: D10="z")))/SUM((B1:B10="x")*(C1:C10="y")*(D1:D10="z")) enter with control+shift+enter to add braces around the whole. liory < wrote: Please help!
