<p>After actively observing CV for some time I'd say that the recipe for a question to get noticed and highly upvoted is:</p>

<ul>
<li>Make it general rather then narrow,</li>
<li>Use a short, meaningful, but "catchy" title,</li>
<li>Make it nicely formatted, use <code>code formatting</code> and $\TeX$,</li>
<li>It should consist of a few sentences and should not be one sentence: an overly long question would mean that people would not read it carefully,</li>
<li>Use <a href="https://stats.stackexchange.com/questions/tagged/machine-learning" class="post-tag" title="show questions tagged &#39;machine-learning&#39;" rel="tag">machine-learning</a>, <a href="https://stats.stackexchange.com/questions/tagged/bayesian" class="post-tag" title="show questions tagged &#39;bayesian&#39;" rel="tag">bayesian</a>, or <a href="https://stats.stackexchange.com/questions/tagged/p-value" class="post-tag" title="show questions tagged &#39;p-value&#39;" rel="tag">p-value</a> tags, they always attract attention!</li>
<li>Ask about something controversial,</li>
<li>Ask as a high-rank user!</li>
<li>Include mathematical formulas,</li>
<li>Provide an example,</li>
<li>Don't use <a href="https://stats.stackexchange.com/questions/tagged/self-study" class="post-tag" title="show questions tagged &#39;self-study&#39;" rel="tag">self-study</a> tag.</li>
</ul>
