Document Summary
Data information: sampling errors, coverage errors, response errors, non-response errors, processing errors, estimation errors, analysis errors. Determine which of the following statements are reliable. Using your knowledge from this chapter, list the possible problems with each statement: the average annual income of canadians is. ,100 according to a survey carried out in. Oshawa: a large majority of people from rural areas support subsidies for failing farm operations. Answers: no, this statement is not reliable. This statistic is a result of an inappropriate estimation because of its unrepresentative sample. Choosing oshawa as a representative population neglects regional variations including industry (i. e. , resource-based, tourism, manufacturing, high-tech), employment (i. e. , seasonal, permanent) and labour type (i. e. , retail, government). In order to have a representative sample, the statistician must gather information from many different areas across the country, including rural, semi-urban and urban areas: no, this statement is not reliable.
