What is meta? ×
Meta Stack Exchange is where users like you discuss bugs, features, and support issues that affect the software powering all 134 Stack Exchange communities.

Just out of idle curiosity I thought I'd check how many of my answers had been accepted. The only way I could see was to manually count.

Would people be interested in seeing this as a statistic on the profile page?

BTW - mine's about 11% (28 ish / 264) - it's ish because I gave up counting and didn't want to count my answers to my questions that I'd accepted.

NOTE: This is not the same as the current now removed "Accept Rate" - i.e. how many questions have accepted answers.

You're rocking it up the charts at 71% on Meta now. –  random Aug 23 '09 at 10:52

@jeff: I don't think that's not what OP meant. What is the percentage of provided answers has been accepted? And it seems like it's a number from SO, not meta. –  SilentGhost Aug 23 '09 at 11:16

Yeah, the number of a user's questions for which they have accepted any answer seems like a less useful measure of how much that user contributes to SO. –  Greg Hewgill Aug 23 '09 at 11:23

Okay, this just convinced me that showing the accept rate is a good thing: stackoverflow.com/questions/1318311 –  balpha Aug 23 '09 at 11:32
    
That definitely is a user of the system right there. –  random Aug 23 '09 at 11:36

I've previously requested statistics/badges for accepted answers: meta.stackexchange.com/questions/13847/… –  Rich Seller Aug 23 '09 at 11:38

I'm not sure of the value of showing how many of my questions have accepted answers. –  ChrisF Aug 23 '09 at 20:53

Here is the query if you're curious:

select
    uuser.id,
    uuser.displayname,
    count(post.id) as ans,
    count(vote.id) as acc,
    1.0*count(vote.id)/count(post.id) as pct
from uuser
        join post on (uuser.id = post.owneruserid)
        left join vote on (vote.postid = post.id)
    and post.posttypeid = 2
    and vote.votetypeid = 1
    group by uuser.id, uuser.displayname
    order by ans desc;

That doesn't seem right - how come I'm not in that list? I've got 500+ accepted answers. Or is it sorting by total answers? –  Paolo Bergantino Aug 23 '09 at 21:22
    
@Paolo: it is ordered by total answers (note the order by ans desc on the bottom line). –  Kyle Cronin Aug 23 '09 at 22:26
    
@Paolo: yeah it's ordered by total answers. I did notice you had an excellent ratio though, higher than Jon Skeet! I've updated the table. –  Greg Hewgill Aug 23 '09 at 22:32
    
@Greg: What about another table sorted by the accept ration descending. –  Kyle Cronin Aug 23 '09 at 22:56
    
A great many people had a 100% ratio from a single answer which was accepted. Some people had up to a dozen or so answers which were also all accepted. It wasn't obvious to me how many answers were needed before the stats became "interesting". –  Greg Hewgill Aug 23 '09 at 22:58
    
@Greg: Ah, that's understandable. What about ordering by the total number of accepted answers per user? (I'd do this myself, but I don't have a SQL version of the latest dump) –  Kyle Cronin Aug 23 '09 at 23:07

@Greg, your answer has been spShog9d, remember to vote stackoverflow.com/questions/1248764/… up if you find this useful –  waffles Aug 23 '09 at 23:15

This is possible using the advanced search options.

try searching for

It's only possible up to a point (with that point being 1,000). It just says 1,000+ search results rather than the actual number beyond that. –  Martin Smith Dec 18 '12 at 11:27

I think this is a great stat. Also what would be good at a glance is a ratio of Questions to Answers--identify who's and asker and who's an answerer.

There should be a threshold, though. I think that if you don't have a "minimum answers" thing, you'll get a huge skew of folks who have only answered one question. Sort of like when the do all the awards at the end of an NHL season--there's always a minimum number of games played for best save percentage. Otherwise, some minor league goalie who was in for five shutout minutes would win every year.

You can look up slightly stale data on the data explorer. Accepted Answer Statistics (II) shows how many accepted answers you have. To see the most accepted users, look at Top users by accept answer rate.

I'll repeat my comment from a now deleted answer - Thanks for the info and links. I knew I should have put that I knew the stats could be got from the data dump ;). –  ChrisF Jul 25 '11 at 9:45

That was actually one of the rankings I was suggesting here: New User Rankings

I think it would be an interesting metric, but it will almost always be skewed towards people with a lower answer count.

*better answers. –  Shog9 Jul 3 '09 at 18:24
    
Sorry, missed that one. You can suggest this question is closed as a dupe if you like. –  ChrisF Jul 3 '09 at 18:25
    
ChrisF: Yours is different in that you are suggesting it on the profile page while mine was a suggestion for it used as a way of ranking people on the user page. I don't think it's necessary to flag it as a duplicate. –  TheTXI Jul 3 '09 at 18:27
    
OK - cheers. I've actually voted to close myself (would be nice if I could revoke that!) but won't be too upset if it actually gets closed. –  ChrisF Jul 3 '09 at 18:28
    
I've just checked my stats from the link provided by @dbr and I can see @TheTXI's point about skewing towards lower answer count. In one tag I've got a 100% hit rate but I've only answered one question! Perhaps there needs to be a minimum number of answers before this stat is displayed. Then it might also encourage people to answer more! –  ChrisF Jul 3 '09 at 19:29
    
ChrisF: For rankings I definitely agree for a minimum post count, but still the stat will always skew towards lower post counts because every question you answer that is not accepted hurts you ratio further and further. –  TheTXI Jul 3 '09 at 19:36
