Question

A social researcher wants to collect data on study habits of all first-year college students. Her daughter, a first-year college student, offers to hand out brief surveys for her mother at her college library where she studies. Her daughter mails 20 completed surveys back to her mother. Which best describes the 20 completed surveys?
A. a convenience sample that is not representative of all first-year college students
B. a volunteer sample that is a fair representation of all first-year college students
C. a simple random sample biased against male students at the college
D. a simple random sample that is biased against students who were not at the library

Answer 1

Answer:

i would say A. a convenience sample that is not representative of all first-year college students. there are more than 20 first-year college students in the world so obviously only talking to 20 of them won't be representative of /everyone/

and the convenience is that she only handed them out to people in the library; where she spends most of her time, therefore making it more convenient for her.
