I am not so familiar with statistical concepts. I am preparing a questionnaire to measure underlying constructs that affect pedestrian's road crossing behavior. However, I came across this term called "scale". Earlier I used to think that scale simply means measurement scale (e.g. nominal, ordinal, numerical etc.). But I have seen people using the term "scale construction". Could someone me tell me what it means by constructing a scale (as asked in this question: https://www.researchgate.net/post/What_is_the_fundamental_procedure_for_Scale_construction)?
I am sorry for my poor knowledge of statistics.
Update: I have updated the question to be more clear and precise.
