I ran across a very interesting example of this recently.  In a new tab take some time to analyze this chart for yourself and what you think about it.<p><a href="http:&#x2F;&#x2F;geekologie.com&#x2F;2009&#x2F;03&#x2F;percent-of-student-virgins-per.php" rel="nofollow">http:&#x2F;&#x2F;geekologie.com&#x2F;2009&#x2F;03&#x2F;percent-of-student-virgins-per...</a><p>... done yet?<p>So, firstly I see that as you go toward more rigor, overall the rate goes up, with studio art (no rigor, it&#x27;s just a humanities field) at the left and mathematics (full rigor, fully abstract) at the right.  Like this - <a href="https:&#x2F;&#x2F;xkcd.com&#x2F;435&#x2F;" rel="nofollow">https:&#x2F;&#x2F;xkcd.com&#x2F;435&#x2F;</a><p>Interestingly, computer science (of interest to people here) actually isn&#x27;t as far right as you&#x27;d think.<p>But what pops out to everyone!!  There is obviously one MOST interesting fact in the whole figure, the 0 for studio art.  That really got me thinking.<p>Granted, this isn&#x27;t the perfect example because it&#x27;s not just 0 as opposed to 5-7 - the next higher one is 20%.<p>But what you really start thinking is stuff like - &quot;Is it that they didn&#x27;t really have many subjects, just 2 or 3?  what is n?  Is it that these people are lying?  Is it a real fact?&quot; and so forth.<p>The fact that it&#x27;s 0 instead of a few percent immediately raises some questions.
