I am interested in some statistical information about the math.stackexchange website. Especially these two:

What is the average number of visitors of a question before it receives the first answer?

What are the average answer rates per Tag?

    $\begingroup$ Data Explorer might be useful for stuff like this, for example this query. But I doubt it is possible to find statistics about number of views before the first answer. $\endgroup$

  • $\begingroup$ You can see answer rates per tag by going to the tag page, and looking for the "top users" link; for example, the calculus tag has an answer rate of about 90%. $\endgroup$

Stack Exchange does not store views with timestamps; each new view simply increments the view counter. (The way that views are measured excludes frequent reloads by the same user.) However, you can find the distribution of time before first answer.

The answer rate by tag can be found here; although the data is from last year, the pattern has not changed much. The query used there takes the SE definition of answered as "has an answer that is either accepted or has positive score".

My observations suggest that on this site, the majority of questions with only a zero-score answer are in fact satisfactorily answered. So I forked the query and obtained the number of questions by tag, with (blue) and without (red) answers below:

no answer

There are 10 tags in which more than 20% of questions have no answer:

  1. $26.8\%$
  2. $25.08\%$
  3. $24.82\%$
  4. $24.65\%$
  5. $23.27\%$
  6. $22.9\%$
  7. $22.82\%$
  8. $20.93\%$
  9. $20.58\%$
  10. $20.4\%$
