<p>Stats.SE seems to have a few ambiguous / synonymous tags:</p>

<ul>
<li><a href="https://stats.stackexchange.com/questions/tagged/test" class="post-tag" title="show questions tagged &#39;test&#39;" rel="tag">test</a> x 49</li>
<li><a href="https://stats.stackexchange.com/questions/tagged/testing" class="post-tag" title="show questions tagged &#39;testing&#39;" rel="tag">testing</a> x 23</li>
<li><a href="https://stats.stackexchange.com/questions/tagged/hypothesis-testing" class="post-tag" title="show questions tagged &#39;hypothesis-testing&#39;" rel="tag">hypothesis-testing</a> x 497</li>
</ul>

<p>The former two are even missing a description. I'll leave merging and creating appropriate tag wikis to you, but I thought I would mention it.</p>
