I am trying to do a conditional median in Excel. I have 2 columns that
looks like this:

I J
2/7/2011 5
4/6/2011 6.4
5/10/2011 4.4
7/6/2011 4.7
8/23/2011 4.8
9/20/2011 11.8
9/20/2011 4.8
10/4/2011 6.3

I want the median of the cells in B1 where the date in A1 is prior to
today, held in cemm M1.

I tried =MEDIAN(IF(I2:I50<M1,J2:J50)), but that is returning the
median of all values, whether or not the corresponding value in column
J is prior to the date in M1.

I tried searching the forum, but didn't come up with anything.

Any help would be greatly appreciated.

Thanks in advanced.
