Question

question 3 1 pts ch 8 to assess the opinion of students at the ohio state university about campus safety, a reporter for the student newspaper interviews 15 students she meets walking on the campus late at night who are willing to give their opinion. the method of sampling used is

○ a census.

○ the gallup poll.

○ simple random sampling.

○ voluntary response.

Explanation:

• A census involves surveying an entire population, but here only 15 students are interviewed, not the whole student body, so "a census" is incorrect.
• The Gallup Poll is a specific organization's polling method, and this is a local student - reporter survey, so "the Gallup Poll" is not applicable.
• Simple random sampling requires that every member of the population has an equal chance of being selected randomly. Here, the reporter is only interviewing students who are walking on campus late at night and willing to give their opinion, not a randomly selected sample from all students, so "simple random sampling" is incorrect.
• Voluntary response sampling occurs when people self - select to be part of the sample (in this case, the students who are willing to give their opinion). The reporter is interviewing students who are willing to participate, so this is voluntary response sampling.

Answer:

voluntary response.
