Conducted remotely can reduce or prevent geographical dependence
What is an example of population in research?
For example, if you want to carry out a survey to find out student’s feedback about the facilities of your school, all the students of your school would form a part of the ‘population’ for your study. At a more realistic level, a country wants to maintain information and records about all households.
