I have a list of numbers from smallest to largest. The number list varies from 12 to 32 numbers. I want to assign the letter "A" to the lowest 25% of the numbers, a "B" to the next lowest 25%, a "C" to the next lowest 25%, and a "D" to the top 25%. In other words, I want to break down my list into 4 separate groups no matter how many numbers are in the list.
Any help would be greatly appreciated.
