Sorry. I didn't mean for that to sound like a job request. I was more concerned with properly describing my needs that I was at formating my request for suggestions.

I have other scripts that calculate averages for these columns, and I will include that code here. I would like to use DBD::CSV on this, but lack the SQL experience to properly script this with out looping over and over in the file. 
    # Connect to the database, (the directory containing our csv file(
+s))
    my $dbh = DBI->connect("DBI:CSV:f_dir=.;csv_eol=\n;");

    # Associate our csv file with the table name 'results'
    $dbh->{'csv_tables'}->{'results'} = { 'file' => "$CWD/$name"};

    my $sth = $dbh->prepare("SELECT * FROM results WHERE 1=0");
    $sth->execute;
    my @origcols = @{$sth->{NAME}};
    my @cols; # = @origcols;
    shift @origcols; # Eliminate First Column
    foreach ( @origcols ) {
       push ( @cols , $_ ) unless /Bandwidth.*|MSTCPLoop.*/ ; # Remove
+ unwanted columns
    };

    my $avgSQL =
       'SELECT '
       . join(', ', map { "avg($_) \n" } @cols )
       . ' FROM results';
    my @avgs = $dbh->selectrow_array($avgSQL);

    my %avgsHash;
    @avgsHash{ @cols } = @avgs;  # uses a hash slice to populate %avgs
+Hash

    for ( @cols ) {
       (my $changed = $_) =~ s/_/","/;
       printf STATS ("\"%s\",%f\n", $changed, $avgsHash{$_});
    }

Honestly, I have only made a couple of attempts at this. I'm really stumped on how to format the SQL query. I think that is someone could point me in the direction the SQL query should look like, I'd be able to create it.
