(Please Help) A small city conducts a survey to determine how its residents feel about building a public pool facility. Research
ers go door-to-door one day from 9:00 a.m. to 5:00 p.m. to ask if the adult resident would like to complete the survey. What kind of sampling technique is being used? Against which group would the survey most likely be biased? A. Systematic sampling; the sample would be biased against adults who are unemployed.
B. Volunteer sampling; the sample would be biased towards those who complete the survey.
C. Simple random sampling; the sample would be unbiased.
D. Convenience sampling; the sample would be biased against adults who work during the day.
D. Convenience sampling; the sample would be biased against adults who work during the day.
Step-by-step explanation:
Many adults work a typical 9-5 job, therefore if the survey goes on during their full shift, none of them will get to answer. Most people who answer the survey will either be unemployed, or work at night, and no adult with a day job will get to voice their opinion.
