<p>I just noticed that there is a <a href="https://stats.stackexchange.com/questions/tagged/confidence" class="post-tag" title="show questions tagged &#39;confidence&#39;" rel="tag">confidence</a> tag - it does not have a description and it is hard to guess what is its purpose? Is it about confidence intervals (it has multiple questions tagged both [confidence] and <a href="https://stats.stackexchange.com/questions/tagged/confidence-interval" class="post-tag" title="show questions tagged &#39;confidence-interval&#39;" rel="tag">confidence-interval</a>). If yes, then it should be marked as synonym. However if it is not so, then it seems to be ambiguous and is seems to be used incorrectly.</p>

<p>Should we do anything with this tag?</p>
