[Vocabulary] investigation vs. study

[Jack8rkin]

Hello!
Could you please explain me the difference in the meanings of "investigation" and "study" if we speak about a process of research? Are they interchangeable?

Thanks

"Study" is used for an empirical scientific work that is limited by its research methodology. In a 'study', you generally start with a hypothesis that you attempt to reject or accept, thus 'proving' something.

An "investigation" is generally more free of such constraints as using a control group, etc. An "investigation" generally allows for following up leads and changing hypotheses during the request for the truth.

No, I wouldn't call them interchangeable, though there are some cases where you could use either.
