a) A company is investigating working conditions throughout
their operations and has offered employees the opportunity to
complete a questionnaire on this subject. - Voluntary
response sample
(The respondent voluntarily chooses to respond to the
questionnaire)
b) The island nation of South Nakaratu is planning for
development of their public transport system. In order to help with
this, 200 randomly selected citizens of the country are chosen from
the general population and are required to complete a survey
relating to their use of public transport and desired changes. -
Simple random sample
(The sample is randomly chosen from population)
c) It is suspected that a new medical treatment for influenza
may affect men and women differently. A group of 30 males is
randomly selected and a group of 30 women is randomly selected. The
treatment is then applied to this group of 60 randomly selected
people. - Stratified random sample
(The population is divided into strata (male and female) first
and then samples are selected randomly from all strata)
