    Question Newbie in need of help with Frequency function please

    Hi, and apologies for joining and getting straight in with a 'help' request ... but I'm baffled.

    I have a list (about 6000 rows) of numbers. Each number appears between once and 20 times. I'd like to identify the numbers that appear only once. I think I need to use the Frequency function but I'm struggling with understanding it.

    I'd appreciate any help to:
    a) suggest another way of identifying numbers that only appear once
    b) understand the Frequency function to resolve my problem.

    Just to be clear, as a small example...
    2
    5
    5
    7
    7
    7
    8

    I only want to be able to find those that appear once (the 2 & 8)

    Thanks in advance

    Re: Newbie in need of help with Frequency function please

    you can use the countif() function for this. assuming you're data is in column A...

    =IF(COUNTIF($A$1:$A$7,A1)=1,1,"")
    1. Use code tags for VBA. [code] Your Code [/code] (or use the # button)
    2. If your question is resolved, mark it SOLVED using the thread tools
    3. Click on the star if you think someone helped you

    Thanks for the quick reply FDibbins. I've tried that to no avail ... is it my usage:
    =IF(COUNTIF($S$1:$S$5758,S1)=1,1,"")
    The result is 1?

    thats what you asked for, wast it? that formula will give you, in column B, a list of only those entries that appear only once. if you want to see just that list, you can apply filters and filter on that column

    Cheers ... but that formula doesn't work

    No matter what data you run that against, the answer is always 1.

    Thanks for trying - very much appreciated

    Hi chan73

    This works, you need to enter the formula somewhere in row 1 and copy down to row 5758. I don't think that is what you require! I think you are after a formula that returns a list numbers that only appear once.

    Formula: copy to clipboard
