It is nice that people can ask questions and get answers to whatever question they have. However, we tend to close and deleted questions when they are out of the bounds of the website (not interesting to pursue for the sake of creating a database of questions with related answers).
Currently, we do this for duplicates, broad questions, unclear questions, unfocused questions, and off-topic questions.
Among, the off-topic questions we may have self-study questions that get closed because the OP did not do a lot of research themself.
Among these off-topic questions, we could also regard extremely simple/basic/beginner questions (that show signs of low level or little research effort). But it is not so clear how to deal with them.
I am thinking of this question:
Can a regression formula be Y=A - BX
That question is a bit trivial and simple. But it is a bit strange to close it based on little research effort (it is more like the OP is just at a very early stage of research and can't be blamed for asking a basic question). How should we deal with those?
