<p>By the way, we could make wikis few questions that appear here again and again and are so marked as duplicates. There are at least a few examples of questions that appear and it would be good if there were one <em>comprehensive</em> answer, or set of answers, that could be referenced while marking duplicates.</p>

<p>The type of question that comes to my mind is, e.g., "What is and how to interpret a p-value?". There are multiple threads for this so it is even hard to mark duplicates and reference the already answered questions since you have to review many of those by yourself to find the best. I imagine also that lack of a single comprehensive answer makes some people ask "new" questions that are in fact duplicates of others lost somewhere between hundreds of similar ones.</p>
