In my experience, you're best off storing the raw data, then generating
statistics in a separate step.  That way, if you decide that you want to
generate different statistics (mean vs. mode, for example) you still have
the raw data to do so.

If you're storing the results in a flat file, just have have the script
append the new results to the end of the file, then have another process
that comes along and reads the file, and generates a different file with
the statistics.

Of course, this is even easier if you're using a database.
