Since October 2015 a "How to ask?" page is shown before a user asks their first question on this site, and they need to confirm that they read it; see here: Show “how to ask” advice before a new user asks a question. (The post announcing that this was implemented is from October 15.)
Do we have some statistics which can help to evaluate whether this change has made some impact? (This question is somewhat similar to: Registration to ask a question – has it made a difference?)
Basically, I am asking two questions in one:
- Which statistics should we look at?
- Where can we get those statistics?
Which statistics should we look at? Which numbers would describe changes in positive direction? Should we look at percentage of questions that were deleted? Percentage of question (or first questions) that were closed?
Where can we get those statistics? There is a page with site analytics, however, I am not sure whether this is of much help here. (I do not see anything about closures and deletion there. It is possible that moderators have access to more detailed stats in the site analytics.) We could also use some data from Data Explorer (SEDE). (Some data will be necessarily skewed, since SEDE contain only limited information about deleted posts in the PostsWithDeleted table. However, I have been told by more experienced users that CMs have the option to run SEDE queries also on the data-set, including the deleted posts - so if we are able to come up with something useful, we might ask them for help.)
