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 363 students about their eating habits. What type of sampling is used? ... A. Simple random sampling is used, because students are chosen at random. O B. Stratified sampling is used, because students are divided into groups, and students are chosen at random from these groups. O C. Convenience sampling is used, because students are chosen due to convenience of location. O D. 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. O E. Systematic sampling is used, because students are selected from a list, with a fixed interval between students on the list. 4 What potential sources of bias are present, if any? Select all that apply. A. University students may not be representative of all people in their age group. B. 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. D. There are no potential sources of bias.
