• @Dave It is just a term used in this question. Please ignore it. Oct 17, 2020 at 7:47
• The questions may make more sense given some context. At best, you have been told about a small number of named distributions and are asked to guess which might be most appropriate. Even so, the question can't be answered without knowing which distributions are candidates. Several of your answers suggest "normal" for distributions that are in principle discrete. Answers of "no idea but show me some data and I will give you some comments" or "is there any reason why that should follow a named distribution?" are presumably not expected, but are likely from anyone experienced.
