Are closed questions impacting the statistics at area 51?

Question

In Islam at Area 51, it says we have 83% questions answered while we should work to get more: "90% answered is a healthy beta, 80% answered needs some work. In the beta it's especially important that when new visitors ask questions they usually get a good answer."

Are questions that get closed included in this statistics? If that is the case wouldn't more closed questions result in less % answered questions?

Answer 1

Questions per day

According to this meta.SE thread, this is the median daily number of questions in the last two weeks. Comparing the numbers for created:14d.. is:question with created:14d.. is:question closed:false, it looks like it includes closed questions.

Answered ratio

This is answered at meta.SE by Emmett (copy/pasted below). If this is accurate, closed questions are counted the same as answered questions. So closed questions with no upvoted answers will increase the ratio.

Avid/total users

Does not affect the calculation (but closing people's questions may affect whether or not they become avid users).

Answer ratio

According to Emmett's answer, closed questions with no answers will increase both total_questions and answeredPercentage, lowering the answer ratio.

(I'd guess this is affected somewhat by goldPseudo's tendency to diamond-hammer delete worthless answers.)

Visits per day

Does not affect the calculation (but closing questions would affect the visits per day).

Emmett's answer:

We use numbers returned by the public /stats api, e.g. http://api.gaming.stackexchange.com/1.1/stats:

answeredPercentage = 100 - (total_unanswered / total_questions * 100);
answerRatio = total_answers / (total_questions * answeredPercentage / 100);

But slightly confusingly, the api's return values for total_questions and total_answers include closed questions, but total_unanswered doesn't.

So, answeredPercentage ("% answered" on the stats page) is actually "percentage of questions that have been resolved" ...either by an answer or by closing.

Answer 2

Closed questions will not count towards the Unanswered metric.
