Answer

# Brief Explanations: The researcher is choosing students as they leave a dorm, which is convenient in terms of location, so it's convenience sampling. For bias, personal nature of the question can lead to dishonest answers, university students may not represent all in their age - group, and since it's a convenience sample, the easily - accessible members may not represent the whole population. # Answer: Sampling technique: E. Convenience sampling is used, because students are chosen due to convenience of location. Potential sources of bias: 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.
