How long is the average wait time to have a question answered? I know that most people have lives outside of this forum so I know people may not have time to skim through the current unanswered questions.

There are several questions I have seen that have not been answered in several years. This person's question hasn't been answered in 2 1/2 years.

    $\begingroup$ See Distribution of time to first answer in MathStackExchange? which is a bit dated (December 2013). $\endgroup$

    $\begingroup$ Instead of "average", why not ask for "median"? Then it won't be made undefined by unanswered questions. $\endgroup$

    $\begingroup$ It seems that the oldest unanswered question is this one: An elegant description for graded-module morphisms with non-zero zero component, from July 2010. $\endgroup$ Apr 11, 2015 at 13:23

    $\begingroup$ So, according to pizza's link: the median time to answer is 23 minutes. That is as of 2 years ago. And only answered questions are counted. $\endgroup$

    $\begingroup$ The distribution of time post is quite antiquated in its information. I want average not median because the median is extremely undescriptive of a set. Ex. 1 (1,1,1,5,10) median is 1 and average is 3.6. quite a diferrence. I have a hard time believe it is 23 minutes. $\endgroup$

    $\begingroup$ @Aethelred the average is exactly as undescriptive as the median, for example the set $S=\{1,1,1,1,1,1,1,1,1,10^{132}\}$ has average $(10^{132}+9)/10 \approx 10^{131}$. Having the average and the median is interesting (in particular because you can compare them). $\endgroup$

    $\begingroup$ If at least one question has no answer (ever), then the mean time for answers is infinite. $\endgroup$
