<p>Our <a href="https://stats.stackexchange.com/questions/tagged/pearson" class="post-tag" title="show questions tagged &#39;pearson&#39;" rel="tag">pearson</a> tag (220 questions) is ambiguous and seems to be used inconsistently: it can refer either to Pearson's correlation or to Pearson's chi-squared goodness of fit test.</p>

<p><strong>I think it should be split into <code>[pearson-r]</code> and <code>[pearson-chi-squared]</code>.</strong></p>

<p>Afterwards we should map <code>[pearson-chi-squared]</code> (and <code>[pearson-goodness-of-fit]</code>?) to <a href="https://stats.stackexchange.com/questions/tagged/chi-squared" class="post-tag" title="show questions tagged &#39;chi-squared&#39;" rel="tag">chi-squared</a> (1100).</p>
