Dr. Harrison is investigating the impact of threat-appeals (fear arousal) in public health campaigns designed to reduce vaping among young adults. He plans to recruit participants from a local further education college using a volunteer (self-selecting) sampling technique.
Dr. Harrison intends to show his participants one of two versions of an anti-vaping advertisement. In Condition A, the advertisement focuses on the severe physiological risks of vaping (high fear appeal), whereas in Condition B, the advertisement focuses on the social and financial consequences of vaping (low fear appeal).
Describe how Dr. Harrison could obtain his sample of participants using a volunteer sampling technique.
