Essay

Your book suggests that there are three questions that you need to ask to assess sample quality. What are they? Then answer each of those three questions for this sample: CDC's NISVS study, noninstitutionalized (e.g., not in nursing homes, prison, and so on) English- and/or Spanish-speaking residents aged 18 and older were randomly selected through an RDD sampling method in 2010. A total of 9,970 women and 8,079 men were selected. Approximately, 45% of the interviews were conducted by landline and 55% by cell phone. The final sample represented the U.S. population very well. For example, the proportion of the sample by gender, race/ethnicity, and age in the NISVS sample was very close to the sample proportions for the U.S. population as a whole.
