What is a key strength of a volunteer sample?

A key strength of a volunteer sample is that it is inexpensive and time-efficient. This sampling method often involves recruiting participants who are willing to take part in research out of their own interest or motivation, which can significantly reduce costs associated with recruitment and participant compensation. Additionally, using a volunteer sample typically requires less time to gather participants compared to other sampling methods, such as random sampling, which may require more extensive outreach efforts.

In the context of research, volunteer samples can quickly yield a group of participants ready to engage, optimizing the researcher's time and resources. This efficiency is particularly advantageous in studies where quick data collection is paramount or when funding is limited.
