    Finding a specific set of data, and then the min value within this set

    Dear all,

    I am trying to create a formula that will find a set of numbers within a column, and then find the 'min' value of that specific set. For example, in the data below, I want to find a min amplitude between each time interval written across the top. So an example of this would be the 'min' amplitude between time intervals 0 and 10 would be -33.26416, and the min amplitude between times 11 and 20 would be 0.610.

    I need to do this with about 100,000 amplitude data points which are between about 600 time intervals. I have already tried pulling out the amplitudes within a specific time interval to the columns underneath the time intervals, and then getting a min value for each column, but I have way too much data for this to realistically work.

    Could anyone please help me with a formula that does not need to be dragged across an area of 100,000 by 600?

    Any help on this would be very much appreciated.

    Timothy

    Re: Finding a specific set of data, and then the min value within this set

    Try this array formula

    =MIN(IF(($A$4:$A$25>=0)*($A$4:$A$25<=10),$B$4:$B$25))

    Then change the 0 to 11, and 10 to 20 for the next formula, etc..

    ...confirmed by pressing CTRL+SHIFT+ENTER to activate the array, not just ENTER. You will know the array is active when you see curly braces { } appear around your formula. If you do not CTRL+SHIFT+ENTER you will get an error or a clearly incorrect answer. Press F2 on that cell and try again.

    Thanks for the answer, it works perfectly.

    I now have another problem I was wondering if you could help me with. When I pull out the amplitude values, do you know of a way that I can also get the correspondings time values which they are adjacent to?

    I would use an index function (=INDEX($A$4:$A$25,MATCH(MAX(C$3),$B$4:$B$25,0))), but this is not specific enough. It uses the harnesed amplitude values to find the first match in column B and get the time next to this. In reality, I have mulitple repeats of amplitudes throughout column B, and therefore I will just get the first time value instead of the specific adjacent time.

    I hope this message is not too confusing. I have attached another excel file with the new and improved formulas.

    Thanks again

    Tim

    Re: Finding a specific set of data, and then the min value within this set

    =INDEX($A:$A,MIN(IF(($A$4:$A$25>C2)*($A$4:$A$25<=D2)*($B$4:$B$25=C3),ROW($B$4:$B$25))))
    TRY THIS ARRAY FORMULA IN C4 and copy towards right
