volunteer sample

• Volunteer sampling is where the participants select themselves.

  How to obtain/ collect:

  It is obtained by the researcher posting an advertisement. 

  Strengths:

  There is minimal input put in from the researcher in order to choose the participants therefore is less time consuming. 

  Limitations: 

  Creates volunteer bias as they are more likely to be engaged which can attract a certain profile and curious to know what it is about, and they are more likely to please the researcher.
