Questions which are just photographs of your homework sheet or old exam paper Why these questions are closed We have a policy on self-study questions, which says that: It is okay to ask about homework. Homework is included in this self-study tag. This site exists to help people learn and provide a standard repository for questions in statistics and ...

Questions which contain a large number of undefined abbreviations or acronyms One of our close reasons is "Unclear what you are asking." I'm comparing an XYZ model to a YYZ model using the ABC and DAR statistics. Using the LLV test on the OOP dataset, my results are not good. Perhaps I failed at TTR? CrossValidated is a site for everyone, not just ...

I downvoted your question because the part about job-related questions doesn't make sense, and it's unrelated to the site policy: this is a Statistics Q&A - nowhere in the list of questions one should avoid asking is it mentioned that questions related to the OP's job must not be asked. The only valid criterion to judge a question is whether it is a ...

Not carefully developing a question to ask of your data As Scortchi put it (his ellipsis): […] How can I analyze these data? This quip exemplifies questions that describe a dataset and then ask what data-analytical, statistical, mathematical, programmatical, or machine-learning-ical tools to throw at the data—"What do I do with the data?"—without being ...

In order of priority: Flag the post for moderator attention. Downvote the post. (As Glen_b helpfully notes in a comment, if you plan to do this, do it first, because if yours is the deciding vote to delete, you won't be able to downvote afterwards.) If you have enough reputation, vote to delete the post. If you have enough reputation, vote to close it. If ...

I'm sorry, but I don't think this is a useful approach. The questions you are referring to are essentially "please teach me data science". There are just far too many possible flavors. If you set up a general question and answer that future questions of this type can be directed to, this "generic" Q&A will be either a full book-length treatment, or so ...

I'm all in favor of option 3: ask SE to lower the threshold for closing questions from 5 to 3 votes. (Importantly, the same should apply to the threshold for reopening a question. This is also the case at SO.) In addition, at SO, qualified users of 3000 rep minimum can cast up to 50 close or reopen votes per day. Here, we only get 24 close (and presumably ...

I personally like the "questions": I have a dataset consisting of vectors of numbers and I want to predict values from other vector of numbers. Any help will be appreciated. Thx Why it gets closed? First of all, what is the question in here? Is there any? Nothing was asked, so it's hard to answer anything.

"I am working on my dissertation..." Why is this a negative point? It may seem entirely natural as a lead-in, but it's a bad start. We think statistically (what else did you expect?). A large fraction of questions starting like that turn out to be poor questions. Your question isn't doomed by such a start, but you should want to create a good first ...

This is misleading in so far as it implies that closing is always and only done by a moderator. On the contrary, closing as unclear is often done by non-moderators without any moderator intervening. Then a consensus of five high-reputation users is needed. The point otherwise is well taken: "appears unclear to me" does not mean "is unclear to everyone": it ...

What was the chance of this strange personal coincidence? I am perplexed; I just ended a relationship with a guy and 1 month later I meet another guy who has the same first name and the same first initial in the last name. Example : Torrence Tolley (1st guy) & Torrence Tiffen (2nd guy). What is the universe trying to tell me? Yes, that's a real post ...

On-topic: Terminology As long as it's statistical terminology, I say it's on topic. Lots of statistical ideas have multiple names.

On-topic: Notation Notation questions should be on-topic. Notation is critical; it is also often hard to search for. I would be generous with notation that is used in multiple fields such as math and statistics.

It begins "How do I use SPSS to..." I was advised to do [procedure X] in SPSS. Here's a dump of the output. How do I interpret it? Yes, I am singling out SPSS because it is prominently associated with bad questions. Of course there are thoughtful SPSS users out there, newbies and students included. Please formulate your question in a way that ...

A post that shows no concern for its readers does not deserve answers. Teh speling en gramar r 2 terse and so ful of misstakes that we can scarsely reed the queston. Its ovbious teh poster hasnt even red it theyselfs! We should be sensitive to people who are not native writers of English and work to accommodate them. Even so, there's a fairly clear line ...

I have only a little to add to @NickCox's answer. Down-votes do tend to be sticky, which is a pity when the down-voted poster makes the effort to improve their post. I don't see any reason to suppose this is due to anything more than people's disinclination to keep on returning to a post they've down-voted to see whether it's been improved. There are some ...

A small point not covered in the excellent answers so far: a premature (though well intentioned) answer to a currently unclear question can do more harm than good. When a question bears more than one reading; makes false assumptions or relies on implicit, unexamined premises; lacks crucial context—answering it can create much confusion, even mislead ...

QUESTIONS THAT ARE TYPED IN ALL CAPS Why these questions are closed Western languages differentiate between uppercase and lowercase letters. There are commonly agreed rules on when to use which. These rules are well ingrained in almost all speakers of English. The result is that, yes, we can read text that is in ALL CAPS, but it requires additional effort, ...

EDIT: Here is a summary added also in reaction to various comments (some now deleted). Downvoting is not constructive (and not intended to be). It should, mostly, express a view that a post is not useful, although whatever other reasons or motives people may hide remain indiscernible. Downvoting is not informative unless people explain why they downvote. ...

Duplicates or near duplicates This site aims to collect questions and high-quality answers that are useful not only for the OP, but also for other readers who face the same question. This site exists for over 5 years and has seen something like 83,000 questions (as of July 2016). So if you have a question that, for example, relates to a key topic of an ...

[We often don't close these - but I increasingly tend to think we should put them on hold until clarified] The title is: What test should I run? but which contain no indication of any question of interest whatever, instead focusing entirely on a description of the data (and that usually omitting important information), as if the form of the data were the ...

The endless variations on "How do I analyze these data?" are not answerable questions. Full stop. When I first started my career, I worked as a consultant specializing in data science. I didn't know much about math and machine learning, but I learned. (I was a "unicorn" that had some statistics background and some subject matter knowledge which made me ...

To clarify: programming questions are not automatically off-topic here. Instead, they are off-topic if they don't need "statistical expertise to understand or answer"; as we see under Programming in the help/on-topic: if it needs statistical expertise to understand or answer, ask it here I am not criticizing or challenging your response to programming ...

I think that's a good idea. Perhaps we can go one better and migrate their questions to OpenData.SE.

Technical statistical usage sometimes departs from colloquial English usage. (Examples abound, such as the transitive use of "to learn" in the ML community and the use of singular nouns among statisticians to refer to entire families of distributions. And that's not even touching on the severely technical meanings of "confidence," "error," "fit," "...

I understand the need to make questions clear when asking them and agree telling the OP to make the question clearer, if it is not, is a good thing. But can't this be done without locking the ability to post potential answers? If the question is unclear, then it is rather unlikely to get a high-quality answer and we don't want this site to be a ...

Some excellent and thoughtful comments in existing answers from long-standing members still leave a little scope for additional remarks, from the Dark Side if you will. Some respected colleagues here seem to be leaning towards an ideal of indefinite courtesy, namely that people posting poor questions may require and deserve support until their questions ...

I agree -- where feasible we should try to help the poster understand how to fix their post, including trying to explain what's unclear whenever we're able to do so. However, if someone else's comment covers the main issues, I think it's fine not to add anything when voting to close, though as amoeba points out it would be good to upvote the comment that ...

@Tim is right: users will be automatically banned by the SE system from asking (answering) questions if they have too many posts that are negatively scored, closed, or deleted. The exact parameters of the ban are not disclosed, even to moderators. The moderators do not have the ability to impose or lift it. That said, you don't have to wait for that ban to ...
