excel random sample with criterion
Here is a neat trick:
The usual technique is to put =RAND() down column C and then sort by column
C. This will shuffle cols A & B. Instead put:
=(A1="A")*100 + RAND() in C1 and copy down. Now each sort (descending) will
put all the "A"'s at the top in a random order.
Just keep picking B1 after each sort.

I need to create a macro or function that will pull a random sample from
column B, but only when the criterion in column A is met. For example:
Column A Column B
A 123
A 456
A 789
B 234
I need to pull a random sample of the values in column b, but need the
ability to select the column A value. I was hoping for a button or formula
that i could move from sheet to sheet since we get a system generated list
each week.
