identify the sampling techniques used, and discuss potential sources of bias (if any). explain. every twentieth person entering a sporting goods store is asked to choose his or her favorite sport from a list of five different sports that includes a description of each. a. convenience sampling is used, because the researchers contact the easiest people to reach. b. simple random sampling is used, because every sample of a given size has an equal chance of being selected. c. cluster sampling is used, because the population is divided into groups, several groups are selected, and every person in those groups is contacted. d. systematic sampling is used, because every twentieth person is selected. e. stratified sampling is used, because the population is divided into groups, and random samples are taken from each group. what potential sources of bias are present, if any? select all that apply. a. people who do not enter the sporting goods store are not sampled. b. if there is a regular pattern to the people entering the sporting goods store, the sample may not be representative. c. the wording of the question may direct respondents towards a particular sport. d. there are no potential sources of bias.

Answer

# Brief Explanations: 1. **Sampling technique**: Since every twentieth person entering the store is selected, this is systematic sampling. In systematic sampling, elements are selected at regular intervals from an ordered population. 2. **Sources of bias**: - People who do not enter the sporting - goods store are not sampled. This means the sample only represents those who visit the store, not the entire population interested in sports. - If there is a regular pattern to the people entering the store (e.g., only sports - enthusiasts visit during certain times), the sample may not be representative of the general population. - The wording of the question may direct respondents towards a particular sport if the descriptions are written in a leading way. # Answer: 1. Sampling technique: D. Systematic sampling is used, because every twentieth person is selected. 2. Potential sources of bias: A. People who do not enter the sporting goods store are not sampled; B. If there is a regular pattern to the people entering the sporting goods store, the sample may not be representative; C. The wording of the question may direct respondents towards a particular sport.
