[Stephen_IV]

I have a data set that I would like to have A,B,C,D,E distributed evenly. Below is a sample, I would like to use this on a larger data set. If anyone has a Function or VBA I would appreciate it. Thanks in advance!

[Rick Rothstein]

Assuming your data is located in Column A and starts on Row 1 (change the red highlighted text if that guess is wrong), give this macro a try...

Sub RandomEvenDistributionOf()
  Dim R As Long, Cnt As Long, RndIdx As Long, HowMany As Long, What As String
  Dim Tmp As Variant, Data As Variant, Arr As Variant
  Data = Range("[B][COLOR="#FF0000"]A1[/COLOR][/B]", Cells(Rows.Count, "[B][COLOR="#FF0000"]A[/COLOR][/B]").End(xlUp))
  What = "ABCDE"
  HowMany = UBound(Data)
  Arr = Split(Trim(Replace(StrConv(Application.Rept(What, 1 + Int(HowMany / Len(What))), vbUnicode), Chr(0), " ")))
  Randomize
  For Cnt = UBound(Arr) To LBound(Arr) Step -1
    RndIdx = Int((Cnt - LBound(Arr) + 1) * Rnd + LBound(Arr))
    Tmp = Arr(RndIdx)
    Arr(RndIdx) = Arr(Cnt)
    Arr(Cnt) = Tmp
  Next
  Range("[B][COLOR="#FF0000"]A1[/COLOR][/B]").Offset(,1).Resize(HowMany) = Application.Transpose(Arr)
End Sub

Note: If the number of names is not an even multiple of the number of letters you want to distribute, the "odd excess" will be filled randomly from among the letters being distributed.

another VBA option
- if there are 20 students all grades occur 4 times
- if there are 21 students 4 grades occur 4 times, 1 grade occurs 5 times
- if there are 20 students 3 grades occur 4 times, 2 grades occur 5 times
- if there are 20 students 2 grades occur 4 times, 3 grades occur 5 times
- if there are 20 students 1 grade occurs 4 times, 4 grades occur 5 times
- if there are 25 students all grades occur 5 times etc

Sub Distribute()
    Dim Ws As Worksheet, Rng As Range, Cel As Range, M As Integer, C As Long, a As Long, xMax As Long
    Set Ws = ActiveSheet
    Set Rng = Ws.Range("A2", Ws.Range("A" & Rows.Count).End(xlUp)).Offset(, 1)
    Rng.ClearContents
    C = Rng.Cells.CountLarge            [I][COLOR=#006400]'number of students[/COLOR][/I]
    M = C Mod 5                         [COLOR=#006400][I]'remainder when C is divided by 5[/I][/COLOR]
    xMax = (C - M) / 5                 [I][COLOR=#006400] 'max occurrence for even distribution[/COLOR][/I]
[I][COLOR=#006400]'allocate excluding remainder[/COLOR][/I]
    For a = 1 To C - M
        Set Cel = Rng(a, 1)
        Cel = Chr(WorksheetFunction.RoundUp(Rnd * 5, 0) + 64)
        If WorksheetFunction.CountIf(Rng, Cel) > xMax Then a = a - 1
    Next a
[I][COLOR=#006400]'allocate the remainder[/COLOR][/I]
    For a = C - M + 1 To C
        Set Cel = Rng(a, 1)
        Cel = GetGrade
        If WorksheetFunction.CountIf(Rng, Cel) > xMax + 1 Then a = a - 1
    Next a

End Sub

Student names are in column A starting at A2 (without any blank cells)

Results will differ every time the code is run

After obtaining the results, you must copy column C and paste as values ​​so that the results no longer move.

    Dim Ws As Worksheet, Rng As Range, Cel As Range, M As Integer, C As Long, a As Long, xMax As Long
    Set Ws = ActiveSheet
    Set Rng = Ws.Range("A2", Ws.Range("A" & Rows.Count).End(xlUp)).Offset(, 1)
    Rng.ClearContents

    For a = 1 To C - M
        Set Cel = Rng(a, 1)
        Cel = Chr(WorksheetFunction.RoundUp(Rnd * 5, 0) + 64)
        If WorksheetFunction.CountIf(Rng, Cel) > xMax Then a = a - 1
    Next a
[I][COLOR=#006400]'allocate the remainder[/COLOR][/I]
    For a = C - M + 1 To C
        Set Cel = Rng(a, 1)
        Cel = [COLOR=#ff0000][B]GetGrade[/B][/COLOR]
        If WorksheetFunction.CountIf(Rng, Cel) > xMax + 1 Then a = a - 1
    Next a

End Sub

What is GetGrade (see red highlighted text above)? This seems to be the only appearance of it in all of your posted code.

Also, you need to include a Randomize statement in your code or I think it will repeat the same sequence each time the workbook is opened.

Thanks @Rick Rothstein


ooops
I had a function which I decided to remove - changed one line and forgot to change the other !!
Of couse it still worked for me

Sub Distribute()
    Dim Ws As Worksheet, Rng As Range, Cel As Range, M As Integer, C As Long, a As Long, xMax As Long
    Set Ws = ActiveSheet
    Set Rng = Ws.Range("A2", Ws.Range("A" & Rows.Count).End(xlUp)).Offset(, 1)
    Rng.ClearContents
    C = Rng.Cells.CountLarge            'number of students
    M = C Mod 5                         'remainder when C is divided by 5
    xMax = (C - M) / 5                  'max occurrence for even distribution
'allocate excluding remainder
    For a = 1 To C - M
        Set Cel = Rng(a, 1)
        [COLOR=#006400]Cel = Chr(WorksheetFunction.RoundUp(Rnd * 5, 0) + 64)[/COLOR]
        If WorksheetFunction.CountIf(Rng, Cel) > xMax Then a = a - 1
    Next a
'allocate the remainder
    For a = C - M + 1 To C
        Set Cel = Rng(a, 1)
        [COLOR=#006400]Cel = Chr(WorksheetFunction.RoundUp(Rnd * 5, 0) + 64)[/COLOR]
        If WorksheetFunction.CountIf(Rng, Cel) > xMax + 1 Then a = a - 1
    Next a
End Sub

@Rick Rothstein - tested that and you are correct
