<p>I wonder if <a href="https://stats.stackexchange.com/questions/tagged/joint-distribution" class="post-tag" title="show questions tagged &#39;joint-distribution&#39;" rel="tag">joint-distribution</a> and <a href="https://stats.stackexchange.com/questions/tagged/bivariate" class="post-tag" title="show questions tagged &#39;bivariate&#39;" rel="tag">bivariate</a>, have been used interchangeably on Cross Validated?</p>

<ul>
<li>[joint-distribution] was used in 255 questions; it has an excerpt and a simple wiki. </li>
<li>[bivariate] was used in 126 questions; it has a simple excerpt and no wiki.</li>
</ul>

<p>Can they be considered synonyms? If not, would it be interesting to update the tag excerpts to emphasize what is (are) the difference(s) between them?</p>
