Explanation:
In Statistics, sampling can be defined as a process used to collect or select data (objects, observations, or individuals) from a larger statistical population using specific procedures.
There are various types of sampling used by researchers and these are;
1. Random sampling.
2. Systematic sampling.
3. Stratified sampling.
4. Cluster sampling.
5. Opportunity or convenience sampling.
An unobtrusive data collection is a data collection technique used mainly in the social sciences to obtain or gather data without the researcher directly interfering or interfacing with the subject being studied. Thus, it doesn't influence the behavior, action or response of the subjects under study.
Hence, an example of unobtrusive data collection is examining body camera footage to determine the extent of excessive use of force among police departments.
Its been a while since I did this topic, but I believe it was mostly because under communism there was little work for intellectuals, so they were often the ones who left the country. This resulted in a 'brain drain', a lack of knowledgable people. I seem to remember reading about the entire maths department of a university just up and leaving at one point. You could also argue that it was damaging for the image of communism if so many people were trying to leave.
