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 an academic building, a researcher asks 373 students about their eating habits. what type of sampling is used? a. stratified sampling is used, because students are divided into groups, and students are chosen at random from these groups. b. simple random sampling is used, because students are chosen at random. c. 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. d. systematic sampling is used, because students are selected from a list, with a fixed interval between students on the list. e. 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. the sample only consists of members of the population that are easy to get. these members may not be representative of the population. b. university students may not be representative of all people in their age group. c. because of the personal nature of the question, students may not answer honestly. 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 an academic building. This is convenience sampling since students are chosen based on the convenience of their location (being at the academic building at that time). 2. For the bias - question: - Option A is correct because convenience sampling often results in a sample of easily - accessible members of the population, which may not be representative. - Option B is not relevant to the sampling method used here as the focus is on the representativeness of the student body at the university, not of all people in the age group. - Option C is correct as eating habits can be a personal topic, and students may not answer honestly. # Answer: What type of sampling is used? E. Convenience sampling is used, because students are chosen due to convenience of location. What potential sources of bias are present, if any? A. The sample only consists of members of the population that are easy to get. These members may not be representative of the population. C. Because of the personal nature of the question, students may not answer honestly.
