identify the sampling techniques used, and discuss potential sources of bias (if any). explain. assume the population of interest is the student body at a university. questioning students as they leave a university parking lot, a researcher asks 369 students about their drinking habits. what type of sampling is used? a. systematic sampling is used, because students are selected from a list, with a fixed interval between students on the list. b. stratified sampling is used, because students are divided into groups, and students are chosen at random from these groups. c. convenience sampling is used, because students are chosen due to convenience of location. d. simple random sampling is used, because students are chosen at random. e. cluster sampling is used, because students are divided into groups, groups are chosen at random, and every student in one of those groups is sampled. what potential sources of bias are present, if any? select all that apply. a. because of the personal nature of the question, students may not answer honestly. b. university students may not be representative of all people in their age - group. c. the sample only consists of members of the population that are easy to get. these members may not be representative of the population. d. there are no potential sources of bias.

Answer

# Brief Explanations: 1. For the sampling - type question: The researcher is questioning students as they leave a university parking lot. This is convenience sampling since the selection is based on the convenience of the location (the parking lot). 2. For the bias - source question: - Option A: Questions about drinking habits are personal, so students may not answer honestly. - Option C: Since it's convenience sampling, the sample consists of easily - accessible members of the population, who may not be representative of the entire student body. # Answer: What type of sampling is used? C. Convenience sampling is used, because students are chosen due to convenience of location. What potential sources of bias are present, if any? Select all that apply. A. Because of the personal nature of the question, students may not answer honestly. C. The sample only consists of members of the population that are easy to get. These members may not be representative of the population.
