Hi. My data table looks like this - located in D1:E8 Stock Condition IBM TRUE IBM TRUE IBM FALSE IBM TRUE IBM FALSE GOOG TRUE GOOG TRUE I am trying to find a formula (B2) for this table - located in A1:B2 IBM Match #1 60% Where the formula in B2 looks at my data table, finds rows that have the value in A1, then returns the result of the calculation (# of "TRUE") divided by (Total Number) - in the case for IBM, 3 divided by 5. Thank you in advance.

Try this in cell B2: =SUMPRODUCT(--(D1:D1949="IBM"),--(E1:E1949=TRUE))/SUMPRODUCT(--(D1:D1949="IBM")) Slight modification: =SUMPRODUCT((D1:D1949="IBM")*(E1:E1949=TRUE))/SUMPRODUCT(--(D1:D1949="IBM")) See this site for a great description of how sumproduct works: http://www.xldynamic.com/source/xld.SUMPRODUCT.html You may want to try IBM in cell A1 and True in cell A2, an dthis use this function: =SUMPRODUCT(--(D1:D1949=A1),--(E1:E1949=A2))/SUMPRODUCT(--(D1:D1949=A1)) -- Ryan--- If this information was helpful, please indicate this by clicking ''Yes''.

=countif(a1:a10,"IBM") will give you the denominator =sumproduct(--(a1:a10="IBM"),--(b1:b10=true)) will give you the numerator Divide the numerator by the denominator: =sumproduct(--(a1:a10="IBM"),--(b1:b10=true)) / countif(a1:a10,"IBM") And format as a percentage. If you're using xl2007+, there's an =countifs() function you could use, too. About the numerator... Adjust the ranges to match--but you can't use whole columns (except in xl2007+). =sumproduct() likes to work with numbers. The -- stuff changes trues and falsest to 1's and 0's. Bob Phillips explains =sumproduct() in much more detail here: http://www.xldynamic.com/source/xld.SUMPRODUCT.html And J.E.

Thanks Dave. Some of the values in Colb are #NUM! thus the formula returns #NUM!. Can the formula be modified to only look at values that are True/False. Or should the formula in Col B be modified to only return True/False/"Blank" ? Thanks again.

=SUM(IF(ISERROR(B1:B10),"",IF((B1:B10=TRUE)*(A1:A10="ibm"),1,""))) / COUNTIF(A1:A10,"ibm") This is an array formula. Hit ctrl-shift-enter instead of enter. If you do it correctly, excel will wrap curly brackets {} around your formula. (don't type them yourself.) Adjust the range to match--but you can only use the whole column in xl2007. carl wrote: > > Thanks Dave. > > Some of the values in Colb are #NUM! thus the formula returns #NUM!.

Hello all, I am working on a Excel data table. The 3 columns are year(i.e. 2011), dollar amount, purchase dollar amount. I have been asked to group by year in the following buckets. 0-2 years 2-3 years 3-5 years 5-10 years 10+ years I seem to be able to group by 2 year intervals, 3 year intervals etc, but cannot seem to group as I have been asked. That is 2 years, then 1 year, then 2 years, then 5 years. Any help would be greatly appreciated. Thank you!

I’m very interested in the new client backups from DPM 2010, does anyone know exactly how the backup system will work. From what I understand you can set path and file types not to be backed up, but then does it work on a normal/incremental type backup, or block level. Will the “full” backup only happen one time, and then all future backups be block levels that get applied to full when the retention is up? Basically will it work how DPM works with servers, as in all the data won’t go over the wire after the first full backup? Full backup happens only at one time, all l...

Hi everyone. Using E02 on XP. I am trying to work some formulas and I have the general idea what I need to do. I have a date of birth [DOB] and date of hire [DOH].

In other words, once you attain age 21 and have at least 1 year of service, you are eligible to enroll on the next occuring January 1 or July 1. The ultimate question is "What is the Date of Eligibility?" If DOB is 05/01/1960 and ...
