<p>So we have <a href="https://stats.stackexchange.com/questions/tagged/sample-variance" class="post-tag" title="show questions tagged &#39;sample-variance&#39;" rel="tag">sample-variance</a>, with 6 questions tagged. Three also have <a href="https://stats.stackexchange.com/questions/tagged/variance" class="post-tag" title="show questions tagged &#39;variance&#39;" rel="tag">variance</a> tagged, and all the questions were posted this year.</p>

<p>Simple question, is it desirable? There's also tag <a href="https://stats.stackexchange.com/questions/tagged/estimation" class="post-tag" title="show questions tagged &#39;estimation&#39;" rel="tag">estimation</a> for example. If there's a consensus for it I'll try to improve the tag (and retag questions that deserve it).</p>

<p>But I can see arguments for it, as <a href="https://stats.stackexchange.com/questions/tagged/sample-mean" class="post-tag" title="show questions tagged &#39;sample-mean&#39;" rel="tag">sample-mean</a> exists.</p>
