Hello,

I have a table with 1,500 records and with one column: ID, comprised of numeric data ranging from 1 - 1,591. As the
numbers get higher, the frequency of their appearance increases. But what's important, is not so much any given value
but how many numbers appear within a given range. And yes, I am trying to figure out a cutoff point that will separate
this table into the numbers that appear with the highest frequency (they happen to be larger numbers, in this table)
and numbers that appear less frequently (they happen to be smaller numbers.)
So, I want to know if certain values appear more often than others, kind of like a heat map, except the response would
be in a tabular form rather than in graphic.. Is there a way to use an SQL statement to do this? Can I preselect
the number of ranges and their size, for example: break the table up into 20 ranges. But I can't know
which values each of the 20 ranges will have in advance? I know it's a vague question but I wondered
what you all might say as this kind of question is coming up a lot.

Thank you,
Steve
