Group number values into equal groups

I can't seem to resolve this issue. I have 76 numbers which range from -7 to 25. There are some duplicates. I am trying to form 19 groups of 4 with as close to the same total as possible. Any help would be greatly appreciated.

It would help if you attached a sample Excel workbook - the second yellow banner at the top of the screen explains how you can do this.

Hope this helps.

I hope that I attached it correctly

The following approach gets you somewhere near to what you want, but the totals have a greater spread than in your example. I used columns I onwards, with these formulae in the cells stated:

I2: =INDEX($A:$A,COLUMNS($E:E)+1)

I3: =INDEX($A:$A,40-COLUMNS($E:E))

I4: =INDEX($A:$A,38+COLUMNS($E:E)+1)

I5: =INDEX($A:$A,78-COLUMNS($E:E))

I7: =SUM(I2:I5)

Column I represents Group 1, and you can then copy those formulae to the right, up to and including column AA, to give you the 19 groups. The formulae on row 7 show the totals for each group, varying from 38 to 45, although 9 of them are either 40 or 41 as you requested.

Hope this helps.

Thank you again for your prompt response/help. I was hoping to get another idea/formula that more closely put my groups closer to the average of 40/41. Should I clear this one and create another?

No, stay with this one, and you can certainly leave the thread open for a while in the hope of further replies.
