EBP#2 Chpt 23: Sampling in Qualitative Research

Flashcards covering the logic, types, and tradition-specific methods of sampling in qualitative research.

Qualitative Samples

Samples that tend to be small, nonrandom, and intensively studied.

Logic of Qualitative Sampling

The goal is to discover meaning and uncover multiple realities, rather than generalizing results to a population.

Convenience Sampling

A type of sampling also known as volunteer sampling.

Snowball Sampling

A type of qualitative sampling where early participants help recruit future participants.

Homogeneous Sampling

A sampling strategy involving deliberately reducing variation.

Typical Case Sampling

Selecting cases that illustrate what is typical.

Extreme (Deviant) Case Sampling

Selecting the most unusual or extreme cases.

Intensity Sampling

Selecting cases that are intense but not extreme.

Opportunistic Sampling

Also known as emergent sampling, this involves sampling sequentially during the course of the research.

Disconfirming Cases

Also known as negative cases, used in sequential sampling.

Theoretical Sampling

The selection of participants who can best contribute to an emerging theory.

Data Saturation

The point at which informational needs are met and no new information is being obtained, serving as the guide for when to stop sampling.

Shadowed Data

A factor related to data quality that can affect the determination of sample size.

Ethnography Sampling

Involves mingling with many members of a culture, informal conversations with many informants, and multiple interviews with a smaller number of key informants.

Phenomenology Sample Size

Typically relies on very small samples ranging from $10$ to $15$ participants.

Phenomenology Participant Criteria

Participants must have experienced the phenomenon of interest and be able to articulate what it is like to have lived that experience.

Grounded Theory Sample Size

Typically involves samples of $20$ to $30$ people.

Analytic Generalization

Occurs when researchers strive to generalize from particulars to broader conceptualizations and theories.

Transferability

A concept in qualitative research involving reasonable extrapolation and thick description to allow for analytic generalization.
