Find Min/Max/Average Values when String repeats multiple times.

[geelsu]

I am trying to do some analysis on my backup speeds for our Netbackup system. I can grab the output from the Netbackup GUI and pop it into a spreadsheet. Example result types are in the attached spreadsheet. For each Value SU1, SU2, and SU3 (Column E) I need to find the average, the min and the max for KB/Sec (Column C). Of course, as I fill up the spreadsheet the values SU1, SU2, and SU3 will be interspersed all over the place in Column E. I've tried some simple IF statements in combination with the AVERAGEIF, MAX, MIN, etc functions, but kind of hit roadblocks since I'm not an advanced user of Excel and all it various functions.

Some of my attempts have been:

As well as other. Any ideas would be greatly appreciated.

One way:

Max
=MAX(IF($E$2:$E$19=L$2,$C$2:$C$19))

MIn
=MIN(IF($E$2:$E$19=L$2,$C$2:$C$19))

Average:
=AVERAGEIF($E:$E,L$2,$C:$C)

all copied across. The first two are array formulae:


Array Formulae are a little different from ordinary formulae in that they MUST be confirmed in the FIRST CELL ONLY by pressing CTRL+SHIFT+ENTER to activate the array, not just ENTER. After that, the array can be dragged down as normal, to cover the desired range.

You will know the array is active when you see curly brackets { } - or "curly braces" for those of you in the USA, or "flower brackets" for those of you in India - appear around the outside of your formula. If you do not use CTRL+SHIFT+ENTER you will (almost always) get an error message or an incorrect answer. Press F2 on that cell and try again.

Don't type the curly brackets yourself - it won't work...

Hi geelsu,

A Pivot table will do this but if you create a Dynamic Named Range for the Pivot's data and then Refresh the Pivot, you can do all the above. No formulas needed. See the attached:

Thanks guys. Glenn, I used your suggestion initially since I had some basic formulas already in the spreadsheet. Marvin, I will also explore you suggestion because it does sound intriguing and also lets me learn something new. Have a super weekend.

You're welcome.
