I recently encountered analysis and found it to be a bit confusing and unnecessary, despite the detailed tag info. I then discovered this meta thread about it from 2015 that proposed creating the tag:
Create [analysis] tag? + Update 2017: Delete [analysis] tag?
An answer by amoeba in 2017 proposed deleting it. I won't rehash the arguments here but based on the votes there seems to be support for getting rid of it. For what its worth, AdamO (who proposed its creation) states in a comment on that answer "I can say in confidence that my tag did not help".
Since 2017, the tag has grown from 171 to 465 questions. Shall we get rid of it?
