Is there an Access function equivalent to the Quartile function in Excel?

Does anyone know if there is a built-in function for Access that is equivalent to the quartile function in excel?  
If not, any ideas on how to recreate it?

I am thinking
quartile 0 = min
quartile 1 = sum of range * .25
quartile 2 = sum of range * .50
quartile 3 = sum of range * .75
quartile 4 = max

Sasha,

  There is nothing compareable in Access except for Min and Max, which would give you the lowest/highest value respectively.

This:

quartile 1 = sum of range * .25
quartile 2 = sum of range * .50
quartile 3 = sum of range * .75

 Won't work as that's not what a quartile is.  Given:

  1,2,4,7,8,9,10,12

  The 1st quartile is 3.5.  My understanding of what a quartile is is that its the median of the lower half of a set of data.

In this case we have 8 numbers, 7 is the median and half of that is 3.5.  The 3rd quartile would be 10.5

Help?
Jim.

So,
assuming the data is sorted in ascending order
I could take the first half of the range (based on a record count) and find the median to get the 25% quartile.

then do the same with the upper half for the 75% quartile.?

I'll go test it.  
thanks :)

  Yes, that's my understanding.

I did some reading into quartiles.
apparently it isn't just a percentage, but a median value.
I have a very scary looking equation from the statistics book here that I will try... so as I  finish a project that is due today!

I'll get back to this monday.

Can't you reference the Excel object library, and use it from there?

My problem doing that is that the Excel function requires I pass it a range of cells.  I cant' think of a way to pass that info from an Access query.

ideas?
