  4. The Research Design Concept identification Definitions and measurement Data collection

    Data analysis The Research Process Being intentional, purposeful, and strategic in selecting the real- world focus of research and sources of data Empirical Context, case(s), and/or sample
  5. Empirical Context 01

  6. Empirical Context Aka “research topic or subject” The real-world subject

    matter upon which research focuses; the empirical context may be defined on the basis of many dimensions, including those which are geographic, temporal, historical, cultural, social, political, or functional in nature (and beyond).
  7. The extent to which a particular empirical topic present especially

    promising opportunities for theoretical insights When there are compelling reasons for conducting the research in a given context, such as a lack of necessary/needed relevant information, research support, etc. Theoretical Considerations Substantive Considerations Ease of access to empirical contexts (associated cases and/or samples) Practical Considerations Choosing an Empirical Context
  8. Case Selection 02

  9. Case Selection The process of choosing the single or limited

    set of entities (or events, individuals, organizations, etc) for examination in research. …or… The process of choosing the limited set of entities/events/organizations/etc. to include in research within which samples may reside.
  10. It is true that purposive methods cannot entirely overcome the

    inherent unreliability of generalizing from small-N samples, but they can nonetheless make an important contribution to the inferential process by enabling researchers to choose the most appropriate cases for a given research strategy, which may be either quantitative or qualitative. —Seawright & Gerring
  11. Sample Strategy 03

  12. Sample Strategy The method by which a researcher selects the

    entities (or events, individuals, organizations, etc) from the broader population to measure or otherwise take evidence from.
  13. Purpose Examples Random Maximum generalizability to population Simple random; Systematic

    random; Stratified random Purposive (non-random) When researchers want to study a particular subset of cases (individuals, entities, events, etc.) Quota sample; Key informants; Gerring’s case selection techniques Convenience When practical considerations are the driving priority Social media; Established relationships (friends, work, etc) Snowball Access a “hidden” or opaque population Professional or social relationship networks Sample Strategies
  14. Sampling across Different Research Designs Most Relevant Epistemic Approaches Single

    or multiple data types? Quant or qual? Preferred Sampling Strategy Large-n (>100) descriptive or associational studies Empiricism/Positivism Usually single Quant Random Medium-n (30-100) descriptive or associational studies Empiricism/Positivism Interpretivism Usually single Quant or Qual Random or purposive Small-n (<30) descriptive or explanatory studies Empiricism/Positivism Interpretivism Critical Single or multiple Quant or Qual Random or purposive Mixed-methods descriptive or explanatory studies Empiricism/Positivism Interpretivism Critical Multiple Quant and qual Purposive Case studies Empiricism/Positivism Interpretivism Critical Multiple Quant and/or qual Purposive
  15. Systematic error (i.e. skew) in study data and findings as

    the result of meaningful differences between those who participate in a study and those who do not. Nonresponse bias
  16. Sample Strategy The method by which a researcher selects the

    entities (or events, individuals, organizations, etc) from the broader population to measure or otherwise take evidence from. Case Selection The process of choosing the limited set of entities/events/organizations/etc. to include in research within which samples may reside. Empirical Context The real-world subject matter upon which research focuses; the empirical context may be defined on the basis of many dimensions, including those which are geographic, temporal, historical, cultural, social, political, or functional in nature (and beyond).
  17. Sample Case(s) The limited set of entities/events/organizations/etc. to include in

    research within which samples may reside.
