Document Summary

Still don"t know that much about human sexuality. First step is to identify the appropriate population: a group of people a researcher wants to study and make inferences about. If it"s a representative sample with a lot of people, generally it will be generalizable. Generally can"t study whole population so choose a sample: a part of population. A representative sample can be obtained by using: Three phases of sampling: 1) population is identified, 2) a method for attaining sample is adopted and people contacted, 3) hardest getting the people in sample to participate. Problem of refusal or non-response: the problem that some people will refuse to participate in the sex survey, thus making it hard to have a random sample. Convenience sample: a sample chosen in a haphazard manner relative to the population of interest. Not a random or probability sample: report more activity than there actually is.
