Sometimes there are simple questions, often by newcomers, that could be answered by a one-liner (e.g. "What method to use for my data?"). In most such cases I provide a comment rather than answer since it seems to be more consistent with the general answering policy. However, often such one-liners are helpful and seem to be enough for OP. Would you consider converting such comments to answers as a good or bad practice? The answers would be low quality, but in many cases would get approved (= more closed threads).
Some recent examples:
- Correlation values aren't significant but the coefficients of regression are
- What test should I use to explain a natural phenomenon in three variables?
In both cases comments could be possibly turned into answers and would probably get approved.
In practice we often have not enough manpower (and we are lazy) to answer the simple questions. This produces thousands of unanswered simple questions, many of them that received some comments (basically, see any of the https://stats.stackexchange.com/unanswered - most have on-topic comments, often helpful). In many cases lazy comment-one-liner is the only thing that OP receives on this site. The question is: is it better to provide them, even if low quality, as answers or leave as they are?
