Why is High School/Early-college Level Math so Calculus-Focused?

<p>Plenty of calculus in statistics here:</p>

<p>[Normal</a> Distribution – from Wolfram MathWorld](<a href=“http://mathworld.wolfram.com/NormalDistribution.html]Normal”>Normal Distribution -- from Wolfram MathWorld)</p>

<p><a href=“http://mathworld.wolfram.com/CentralLimitTheorem.html[/url]”>http://mathworld.wolfram.com/CentralLimitTheorem.html&lt;/a&gt;&lt;/p&gt;

<p>AP statistics and college statistics for social science majors just ignore the calculus part to make it simple for students.</p>
