Suppose the researcher mails the survey to the 100 people in the representative sample and only 50 of the people return a completed survey. Can you state that this sample of 50 represents the population? Why or why not?
Suppose a researcher wishes to use stratified random sampling to select a representative sample of 100 people from a population that has the following characteristics:
We cannot conclude from this information whether the sample of 50 is representative of the population. We would need to know the extent to which the characteristics of the sample (women, men; married, single) match the population characteristics. The problem of low response rate in this mail survey, however, makes it unlikely that the sample represents the population.
