Standard Deviation

Hi
I asked this earlier over on the ODTUG-SQLPLUS-L list, not much response

I am working on a problem where I have rows of data and the structure includes 48 elements of data in each row on which i need to calculate the standard deviation for the 48 elements in that row.

I currently have that data in a PL/SQL table in the form of one element to each row in that table as part of the overall package and could use this to calculate it.

1. Can I use stddev on a pl/sql table and if so what column name do I use in the stddev function. The column type in the PL/SQL table is Number. or
2.  Do I need to write it out to a temp table and get it from that.
