... We want to learn :smoke:
Aida .... I know that there is a tendency for someone who is "trained" in the technology and sciences area to focus on the numbers. (And I am certainly not pointing this at you.) But there is more to a "study" than just statistics.
There is an area comprised of "research methodology". That portion concerns itself with the overall design of the study ... the design of the questions ... the demographics to be sampled ... the sample size ... and a number of other factors. After the statistics, there is even an art to how the numbers get "tabulated" and interpreted.
Statistics may be the "science" of the study ... but those "other" things are the art of the study. Raw data is only a part of the overall picture, and are only as good as the research design and methodology.
We all know that some studies can be wrong. We all know that some studies can be purposely slanted. But not all are, of course. And, those who really do have the full knowledge "and experience" with such things can have a rather lucrative and rewarding career. Obviously ... it takes more than a graduate level statistics course to be able to do these things.
At least, that's what I was taught when I learned about this stuff while completing grad school ..... almost 40 years ago .....
