Re: [MS_AccessPros] randomly chosen groups

You can use the Rnd function to do what you want in a query.

Group:  (Rnd([Household Number]) * 4) Mod 4

That will give you a random number between 0 and 3 to assign your groups.  Add 1 if you want groups 1 through 4.  Use that in an UPDATE query to assign the values.

NOTE:  You WILL get random numbers, but there's no guarantee that an equal number of households will be assigned to each group.

I would like to divide a table of family households up into 4 randomly chosen groups using an AutoNumber generated field "Household Number".  Then putting that group number into a field in the table   How can I do this?
