Flour On My Face on "[Plugin: WordPress SEO by Yoast] Uninstalled Yoast and Google Analytics still in my source code"

A few months ago I installed the Yoast plugin on my site, flouronmyface.com. A few days later I uninstalled it. When I view my source code I find this

<script type="text/javascript">//<![CDATA[
// Google Analytics for WordPress by Yoast v4.3.3 | http://yoast.com/wordpress/google-analytics/
var _gaq = _gaq || [];
_gaq.push(['_setAccount', 'UA-XXXXXXXXXX ']);
_gaq.push(['_trackPageview']);

I have no idea how to mess with any coding on my site but need to figure out how to remove this leftover code because now I my GA code twice. I have Google Analytics for Wordpress installed.
