In that case, we’d see experimental studies producing a wide range of findings, including many that showed benefits to mental health from using social media (or that showed harm to those who go off of social media for a few weeks).

A county with, say, 100 inhabitants that has no cancer deaths would be in the lowest category. But if it has 1 cancer death it would be among the highest. Counties like Los Angeles, Cook or Miami-Dade with millions of inhabitants do not bounce around like that.<br> <span class="h-card" translate="no"><a href="https://writing.exchange/@bsmall2" class="u-url mention" rel="nofollow noopener" target="_blank">@<span>bsmall2@writing.exchange</span></a></span> <br> <a href="https://fedibird.com/tags/StatisticsClass" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>StatisticsClass</span></a> <a href="https://fedibird.com/tags/Variance" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>Variance</span></a> <a href="https://fedibird.com/tags/EstimatingMeans" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>EstimatingMeans</span></a></p>
