Countif ?
I will try to make this as short as possible! Here is the situation. I need to count "incidences" based on particular criteria in a spreadsheet that contains up to 50,000 rows in order to creat a series for graphing. Starting in the middle, I wish to count the number of times a particular vaule falls between -2.5 and 2.5. Moving out in either directions, I wish to count the number of incidences in increments of 5 in order fo populate a table with associated counts for each of the following: <-102.5 Between -97.5 and -102.5 (-102.5 AND <-97.5) Between -92.5 and -97.5 (-97.5 AND <-92.5) Between etc to the positive end of the range. Essentially I need counts of teh nember of times a cell in a range falls within +/- 2.5 of the following midpoints: -100+/-95/-90/-85...0...5/10/15...100+ Thanks! -- Walker ------------------------------------------------------------------------ Walker's Profile: http://www.excelforum.com/member.php...o&userid=28037 View this thread: http://www.excelforum.com/showthread...hreadid=475454 |
