Pronunciation: /kənˈviːnɪəns ˈsæm.pəl/ Explain
A convenience sample
is a sample taken from a part of a
that is easy to sample. A convenience sample is not a scientific sample.
An important example of a convenience sample not being a
is the polling done for the 1936 U.S. presidential election.
The pollsters used telephone records and car registration records in
a time when only the more wealthy people could afford such luxuries.
This caused the poll to be skewed towards the opinions of wealthier
Americans. The poll predicted Republican Alf Landon would win against
Franklin Roosevelt by a landslide. In fact, Franklin Roosevelt won.
