Final answer:
Interviewees for qualitative interviews are often chosen using purposive sampling, and different examples of sampling methods are provided such as stratified, cluster, and quota sampling.
Step-by-step explanation:
In the context of qualitative interviews, the selection of interviewees depends on the research design and the purpose of the study. If interviewees are chosen specifically for their relevance to the research problematic, such as their job profile or their experiential insights, this is an indication of purposive sampling, which is typical for qualitative research.
When considering the sampling methods provided:
- Stratified sampling is represented in the example of the soccer coach selecting players from different age groups to form a team, ensuring representation from each specified stratum.
- Cluster sampling is shown where a pollster interviews all human resource personnel in several companies, treating each company as a cluster.
- The example of a researcher interviewing an equal number of male and female teachers represents a form of quota sampling, which is a non-probabilistic version of stratified sampling designed to ensure representation across key characteristics.
It's important to recognize that methodology and ethical considerations, such as avoiding bias and ensuring confidentiality, play a critical role in designing and conducting interviews in social research.
