<p>The bias-variance tradeoff is a specific topic that isn't quite the same as bias or variance (although they obviously overlap).  It seems like questions about it are thus somewhat distinct.  I wonder if it would be better to have a specific tag to group these questions.  At present, we have <a href="https://stats.stackexchange.com/questions/tagged/bias+variance">124 threads</a> with both tags and another 15 that have only one of the tags plus the word "tradeoff".  This implies we may have something like 140 threads on this topic (compared to 634 threads with <a href="https://stats.stackexchange.com/questions/tagged/bias" class="post-tag" title="show questions tagged &#39;bias&#39;" rel="tag">bias</a> and 2374 with <a href="https://stats.stackexchange.com/questions/tagged/variance" class="post-tag" title="show questions tagged &#39;variance&#39;" rel="tag">variance</a>).  </p>
