<p>Some datasets are perennial favorites. Would it make sense to have tags for questions about these? If I'm asking about a specific analysis I want to apply to a dataset, it might be helpful to see whether someone has done something similar to this specific dataset before.</p>

<p>I am thinking of tags identifying questions about</p>

<ul>
<li><a href="https://stats.stackexchange.com/search?q=iris+is%3Aq">the Iris data</a> (currently 284 questions)</li>
<li><a href="https://stats.stackexchange.com/search?q=titanic+is%3Aq">the Titanic data</a> (currently 64 questions)</li>
<li><a href="https://stats.stackexchange.com/search?q=Anscombe+is%3Aq">Anscombe's quartet</a> (currently 19 questions)</li>
</ul>

<p>I thought about including a bullet point about <a href="https://stats.stackexchange.com/search?q=UCI+is%3Aq">the UCI ML data repository</a> (currently 58 questions), but this would probably not be specific enough - better to tag specific datasets from the repository (if we decide to use such tags, and if the dataset in question is "notable enough").</p>
