How to calculate avg from various rows
Hello! Pls excuse if this is a repost. I was logged in, and after I clicked
on Post, the stupid thing wanted me to verify my email addr and my identitiy again, and I had to log back in, so I'm posting again - ARGH. I've been searching for hours and just can't find what I need. I found many articles from Biff, but haven't found examples that meet my criteria and scenario, so I'm turning to you all, 'cuz I believe there's a solution out there somewhere! I'm not too experienced with Excel and formula's, nor the names of some of the items/examples I saw, but if given some things to try, I will. Thanks in advance for the assistance :) I have csv files that convert into excel, of which there are columns with the date, time, and certain #'s in many other columns. I am only interested in the avg from one particular column - let's say it's column G. There are about 2600 rows currently, and will grow over time. Each row has a different time, but it's based on the 24 hr clock/time. For example, row 5 starts with 00:00, row 6 has 01:00, row 7 has 02:00, row 12 is 07:00, row 18 is 13:00, row 28 is 23:00, and then row 29 starts 00:00 again, and keeps doing that, for the most part. Some rows skip some times due to other things. I know how to get the avg from all the times of/over all of the 2600 rows right now, for column G - go to the AutoSum, highlight all the rows in that column, and no pblm. I can also sort the times, so for example, if I only want to see all the times that are 22:00, I can see that, and the #'s for those times show up in column G, which they should. However, since the time of 22:00 isn't in rows (for example) 20, 21, 22, but rather 20, 44, 68, etc., (since it's a 24 hr clock), when I use the AutoSum, and just select the rows that show up in column G, just for the time of 22:00, the #'s shown are as follows: (G3:G2600), and I do NOT want that. I was expecting to see just the rows that have the time of 22:00, but it showed me ALL rows. I also found that I can do a special avg (or something to that effect), where I can manually put in up to 30 different rows, and get the avg for those rows, but the option won't let me put in more than 30 rows, and I don't want to have to do that for all the rows with just a certain time that I want to select - it would take way too long, even if the option would allow up to 1000 rows, for example. Example of what I see after filtering for a particular time, that I then am trying to get the average of column G for all rows shown for time 22:00: Row # Time #'s I'm trying to get avg from, in Column G 20 22:00 10 44 22:00 38 68 22:00 18 and so on.... I don't know how to create a formula to get the avg for just the rows that have a certain time in it. Can it be done, and if so, how??? Please provide exact syntax, 'cuz that's what I will put in, and try. Again, thanks in advance for your assistance! Regards, Paul |

How to calculate avg from various rows
It sounds like you're using autofilter?
If so, use the SUBTOTAL function: =SUBTOTAL(1,G5:G2600) Make sure you put the formula in a row that is outside of the filtered area! I always put subtotals above the data. Or, you can try this array formula** : Assume times are in column B: =AVERGE(IF(HOUR(B5:B2600)=22,G5:G2600)) It'll be a little different for 12:00 AM (00:00)** : =AVERGE(IF((ISNUMBER(B5:B2600))*(HOUR(B5:B2600)=0) ,G5:G2600)) ** array formulas need to be entered using the key combination of CTRL,SHIFT,ENTER (not just ENTER) -- Biff Microsoft Excel MVP "paulk2002" wrote in message ...

How to calculate avg from various rows
Thank you T Valko (Biff?). I saw Bob's answer first, and that did the trick.
I'm not sure I understand all the items you have in your answer, but at least I got it to work with Bob's answer, and I appreciate you supplying one too! I have copied it and will try it out later, for in working with Bob's answer, I can't just copy the formula and paste it into other worksheets. I'm finding I have to edit each and every line in each worksheet, otherwise I get a Value, or other errors, and that's very time consuming, for there's 24 hours in each worksheet, and I have 25 worksheets to do :( Thanks again!
