Good luck and let me know if there is anything I can do for you.
What are the similarities and differences among 1) observational research strategies- is when you 'watch' the test subjects. There usually is very little interaction or disturbance to the subjects on behalf of the researcher. The researcher will gather data by watching, hearing, or reading about the behavior of the subjects. In some cases data is collected by others who know the subjects.
