Question

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 360 students about their drinking 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. convenience sampling is used, because students are chosen due to convenience of location. 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. simple random sampling is used, because students are chosen at random. 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. because of the personal nature of the question, students may not answer honestly. c. university students may not be representative of all people in their age group. d. there are no potential sources of bias.

Explanation:

The researcher is choosing students based on the convenience of their location (leaving an academic building), which is convenience sampling. For potential bias, since the sample is based on easy - to - get members of the population, they may not represent the whole student body. Also, the personal nature of the question about drinking habits may lead to non - honest responses.

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.
