You bet. It's called CPAN. Here is a solution with Statistics::Descriptive

use strict;
use Statistics::Descriptive;

my $stat = Statistics::Descriptive::Full->new();
$stat->add_data(70,74,80,82,68,76);

print "mean: ", $stat->mean(), "\n",
      "sum:  ", $stat->sum(), "\n",
      "var:  ", $stat->variance(), "\n",
      "dev:  ", $stat->standard_deviation(), "\n";

Of course, you won't get much credit for this solution on the test. ;)
