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. ;)

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post, it's "PerlMonks-approved HTML":


  • Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
  • Please read these before you post! —
  • Posts may use any of the Perl Monks Approved HTML tags:
    a, abbr, b, big, blockquote, br, caption, center, col, colgroup, dd, del, details, div, dl, dt, em, font, h1, h2, h3, h4, h5, h6, hr, i, ins, li, ol, p, pre, readmore, small, span, spoiler, strike, strong, sub, summary, sup, table, tbody, td, tfoot, th, thead, tr, tt, u, ul, wbr
  • You may need to use entities for some characters, as follows. (Exception: Within code tags, you can put the characters literally.)
            For:     Use:
    & &amp;
    < &lt;
    > &gt;
    [ &#91;
    ] &#93;
