What is the difference between APPROACH and METHODOLOGY ? ?

Question

tell me ur refrences plz.

Answer 1

To me, "approach" sounds more laidback and casual, while "methodology" implies a an organized and researched plan to be followed to accomplish a goal.

Answer 2

The approach is the generalized concept of the test.  the methodology is precisely what you do to perform the test.  Ideally the methodology is actually doing what you intend in the approach, but if you are not careful, the two things may not be the same.

For example, I could be curious about how medium can cause refraction of waves.  

the approach I could select would be to create an apparatus where I could vary the wavelength in the primary medium and test various secondary mediums and see how that affects the wavelength or angle of the wave movement direction.  

In practice, I would need to perform a series of steps and measurements to mimic this intended approach.  the methodology is the exact procedure that I would perfom in the test: how I would vary the media, change the starting wavelengths, measure the changes following interaction with the second medium, etc.
