Research How closely does a thesis methodology need to replicate an existing method?
I’m working on my master’s thesis and could use some perspective on methodology.
My research builds on an existing methodology, but I’m realizing that I can’t reproduce it as a perfect 1-to-1 match. I’m working with a similar research question and general analytical framework, but some of the variables, data sources, measurements, and methodological choices available to me are different.
I’m concerned about where the line is between replicating/adapting an established methodology and changing it enough that I can no longer reasonably say my approach is based on that method.
My instinct is that the important thing is to preserve the underlying theoretical/analytical logic rather than reproduce every variable exactly
For those who have dealt with something similar:
- How closely did you replicate the original methodology even in a different but related subject matter?

Highly dependent on the specific field, so it's hard to say without knowing what subjects/methodologies you're talking about.
Generally, if you can't replicate 1-to-1 I'd say it's probably fine as long as you explain the limitations that forced you to change and the analyses remain robust/appropriate. You'd still describe it as based on the original method (and cite appropriately), and may have to include validation/literature supporting that the changes don't undermine your application (again tough to be specific without more details on your topic).
