I have a population size of about 600 people whom I need to survey(online) for career options they chose after college and was trying to see what my options for sampling were?
Option 1: Complete survey with all people(census).
Option 2: Pick a random sample, but assuming a response rate of about 20%, it seems like the marginal error rises to about 8% which would make generalizations difficult.
Any help on what a good sampling strategy will help. Ideally, I would like to also make cuts on the population to see how gender,age,location,salary etc. have also made an influence on their decisions.
Well, the population size comes from the number of graduates we have had over the last 10 years and the survey is meant only for them. In that case, would a census be better than a random sample given what i have said in the first post.
Any help will be greatly appreciated.
