An advantage of a volunteer sample is they're more likely to assist with an issue or engage in activism.

Volunteer samples are composed of individuals who willingly offer their time and effort to participate in research. They may have a greater interest or motivation to engage in the topic being studied, such as social activism or helping with an issue. This can make them more likely to actively contribute to the study or be more engaged in the issue being studied. However, this also means that the sample may not be representative of the broader population, as those who do not have the same level of interest or motivation may not have participated.
