Pollsters want to know what percentage of all registered voters in Missoula, Montana, intend to vote in the next election. They visit with 350 people at the downtown shopping mall during one afternoon and ask each person whether or not they intend to vote. Are the target population and the sampled population the same in this case? Explain.

Question 2

Briefly describe three types of nonsampling errors.

Answer to Question 1

In this situation, the target population and the sampled population are not the same. The target population consists of all registered voters in Missoula, Montana. The sampled population, however, consists of anyone in Missoula who was at that mall that afternoon (registered voters or not), thereby excluding a very large portion of the Missoula, Montana, registered voters.

Answer to Question 2

a . Errors in data acquisition: Errors that arise from the recording of incorrect responses.
b. Nonresponse error: Errors that arise when responses are not obtained from some members of the sample.
c. Selection bias: Errors that arise when some members of the target population cannot possibly be selected for the sample.
