<p>I noticed that there are both tags <a href="https://stats.stackexchange.com/questions/tagged/average" class="post-tag" title="show questions tagged &#39;average&#39;" rel="tag">average</a> and <a href="https://stats.stackexchange.com/questions/tagged/averages" class="post-tag" title="show questions tagged &#39;averages&#39;" rel="tag">averages</a>.  Is there any subtle difference in meaning between the two?   That plural form of the tag doesn't have a tag wiki, so I'd suggest making it a synonym of <a href="https://stats.stackexchange.com/questions/tagged/average" class="post-tag" title="show questions tagged &#39;average&#39;" rel="tag">average</a> if it is redundant.</p>
