can be used for a first-year graduate course for statistics students or for a class
withstudentsfrombusiness,sociology,psychology,orbiologywhowanttolearn
about designing and analyzing data from sample surveys. It is also useful for a

neering,agriculture,ecology,medicine,andavarietyofotherdisciplines,andare
selected to illustrate the wide applicability of sampling methods.A number of
data sets have extra variables not specifically referenced in the text; an instruc-
tor can use these for additional exercises or variations. The exercises also give
the instructor much flexibility for course level. Some emphasize mastering the
mechanics, but many encourage the student to think about the sampling issues

othersareopen-endedandencouragefurtherexplorationoftheideas.
■ Ihaveincorporatedmodel-basedaswellasrandomization-basedtheoryintothe
text, with the goal of placing sampling methods within the framework used in
other areas of statistics. Many of the important results in the last twenty-plus
