After selecting the method comes:
1) Which and How people should be interviewed (choosing your sample).
a) Random Sample: where every member of the population have an equal chance of being selected but it might not represent the whole population.
b) Snowball Sample: done by making few contacts and ask them to refer you to other people.
c) Convenience Sample: done by talking to people to whom you have easy access.
The question of "Is the sample representative of the population?" depends on what characteristics are important to the researcher. a nice example was given to show what does a representative sample mean. (page 12)
2) What questions should be asked?
*Its important to remember that what you want to find is somewhat different from what you need to ask.
*When asking students whether a professor is knowledgeable about the subject only answers whether the professor appeared to be knowledgeable since students are not really expert on the subject.
*For a longitudinal study, instead of asking the person "Have you changed?". the interviewer should instead ask the same question of interest several times over time.
*Once questions are written, it should be tested and validated.
