A researcher is studying the relationship between stress and diet among college students. The researcher recruits students by se
nding out an e-mail blast, and then includes in the sample the first 100 male and 100 female students who volunteer to participate. What type of sampling did the researcher use
Using sampling concepts, it is found that convenient sampling was used by the researcher to find the volunteers to participate.
<h3>How are samples classified?</h3>
Samples may be classified as:
Convenient: Drawn from a conveniently available pool.
Random: All the options into a hat and drawn some of them.
Systematic: Every kth element is taken.
Cluster: Divides population into groups, called clusters, and each element in the cluster is surveyed.
Stratified: Also divides the population into groups. Then, a equal proportion of each group is surveyed.
In this problem, the first 100 male and first 100 female students sampled are the ones who volunteer to participate, and volunteering is associated with convenient sampling.
