Study Notes

Sampling Techniques

Snowball sampling: a "weak" technique that involves finding a few potential respondents and asking them to refer others with similar characteristics.
Typical case sampling: involves selecting average, normal cases to show how a phenomenon typically unfolds.
Extreme/deviant case sampling: involves selecting unusual or exotic cases to highlight differences and contrast points.

Theoretical Sampling

Involves selecting incidents, slices of life, time periods, or people based on their potential to manifest or represent important theoretical constructs.
Allows for refinement and elucidation of variations in, manifestations of, and meanings of a concept as found in the data.
Can be challenging to establish a clear and consistent sampling framework.

Stratified Purposeful Sampling

Involves selecting cases based on specific criteria to ensure that the sample is representative of the population.
Strategies of data analysis, description of the case, and cross-case themes are used to determine the sampling framework.

Case Study

Aims to provide an in-depth understanding of a case or cases.
Can be exploratory, revelatory, or multiple-case studies.
Case selection involves determining the boundaries of the case and deciding which cases to study in-depth.

Qualitative and Quantitative Sampling

Qualitative sampling: focuses on providing rich information, involves small sample sizes, and aims to provide an in-depth understanding of a phenomenon.
Quantitative sampling: focuses on representation, involves large sample sizes, and aims to make empirical generalizations.

Convenience Sampling

Involves selecting cases based on convenience or accessibility.
Results can be collaborated by others by examining the data and methodology used.

Semi-Structured Interviews

A half-way approach between structured and unstructured interviews.
Allows for a balance between conversation and direction.
Advantages include exploring unexpected topics and having clear direction.

Interview Guide

Requires avoiding jargon, connecting questions, and ensuring a natural flow of conversation.
Structure should include orienting, describing the study, initial questions, deeper questions, and wrap-up questions.

Probing

Involves asking follow-up questions to deepen and enhance the richness of a response.
Detail-oriented and open-ended questions are used to encourage respondents to talk more.
