Identify the sampling techniques used, and discuss potential sources of bias (if any). Explain. Every tenth person entering a cafeteria is asked to choose his or her favorite meal from a list of five different meals that includes a description of each. What type of sampling is used? O A. Cluster sampling is used, because the population is divided into groups, several groups are selected, and every person in those groups is contacted. O B. Simple random sampling is used, because every sample of a given size has an equal chance of being selected. O C. Systematic sampling is used, because every tenth person is selected. O D. Stratified sampling is used, because the population is divided into groups, and random samples are taken from each group. O E. Convenience sampling is used, because the researchers contact the easiest poople to reach What potential sources of bias are present, if any? Select all that apply. O A. If there is a regular pattern to the people entering the cafeteria, the sample may not be representative. O B. The wording of the question may direct respondents towards a particular meal. O C. People who do not enter the cafeteria are not sampled. O D. There are no potential sources of bias.
