  • 1. Purposeful Keyword Searching: Using Available Tools to Build an Archive of Adolescent Blogs Lois Ann Scheidt Indiana University
  • 2. Purposeful Sampling
    • Qualitative research methods are typically used when focusing on a limited number of informants, whom we select strategically so that their in-depth information will give optimal insight into an issue about which little is known.
  • 3. A Warning About Purposeful Sampling
    • Purposeful sampling should not be haphazard. Care should be taken that for different categories of informants, selection rules are developed to prevent the researcher from sampling according to personal preference.
  • 4. Criterion Sampling
    • Here, you set a criteria and pick all cases that meet that criteria for example, all ladies six feet tall, all white cars, all farmers that have planted onions. This method of sampling is very strong in quality assurance.
