Calculate FREQUENCY based on criteria...
oops, sorry, Countif cannot work with two criteria, my array formula does.

As I wrote elsewhere, I like array formulas.
to count frequency of 10 in 2009, type for instance in cell c10:
=sum((year(a2:a6)=2009)*(b2:b6=10)) then press ctrl+shift+enter
the easiest way is to use Countif formula

Hi there -
Stumped on this one... I want to calculate frequency for items that
meet a certain criteria. In this case, date. I have a bunch of data that
looks like this:
COL-A | COL-B
1/2/09 | 10
1/6/09 | 13
1/8/09 | 10
10/23/08 | 10
2/3/09 | 10
2/9/09 | 10
I want to calculate the FREQUENCY of COL-B data for items that occur in
2009. In the example above, that would be 4 for "10" and 1 for "13".
I'm using this data to create a frequency distribution graph.
thanks in advance!
