Chapter 12: Qualitative Studies-Sampling & Data Collection Flashcards
The primary goal for qualitative sampling is…?
to figure out who would be an information-rich source for the study
Qualitative Studies: Sampling
The sample size for a qualitative study is based on when ___ _______ occurs. What is it?
Data saturation
Data saturation is when no new information is achieved, or redundancy begins to occur.
Qualitative Studies: Sampling
What are the 4 types of Sampling?
1) Snowball
2) Convenience
3) Purposive (2 subtypes)
4) Theoretical
Qualitative Studies: Sampling
_______ sampling for a qualitative study includes volunteers to participate.
At what point of the study may this sampling type be used?
Convenience
May be the first type of sampling trialed.
Qualitative Studies: Sampling
________ sampling is having participants make referrals to people. It is also known as _____ sampling.
Any Disadvantages?
Snowball; AKA Network sampling
Leaving the participant selection up to others can give a skewed sample that might not be the most information-rich sources.
Qualitative Studies: Sampling
_______ sampling is a sampling type adopted after other methods are tried first where the researchers deliberately pick participants to find those that are information-rich.
Purposive
Qualitative Studies: Purposive Sampling
What are the 2 Types of Purposive Sampling?
1) Maximum variation sampling
2) Confirming/Disconfirming Cases
Qualitative Studies: Purposive Sampling
________ cases are cases that strengthen credibility.
________ cases are new cases that challenge the results.
Confirming
Disconfirming
Qualitative Studies: Purposive Sampling
______ _______ sampling involves deliberately selecting cases with a wide range of variation on dimensions of interest.
Maximum variation
Qualitative Studies: Sampling
________ sampling is an evolving process where participants are selected as needed for relevance to the emerging theory discovered.
Theoretical
Qualitative Studies: Sampling + Ethnography
Ethnographers start with a wide range of participants and narrow it down to a set of ___ _______.
Key Informants
Key informants are those knowledgeable about the culture and serve as the researcher’s main link to the inside.
Qualitative Studies: Sampling + Ethnography
What Type of Sources can be used in Sampling?
Ethnography can include sampling things as well as people.
With studying a culture of individuals, it can include people but also meetings or events that occur in the natural setting.
Qualitative Studies: Sampling + Phenomenology
Phenomenology uses a small sample size based on two principles, what are they?
1) All participants must have experienced the phenomenon.
2) All participants must be able to articulate what it is like to have lived that experience.
Qualitative Studies: Sampling + Grounded Theory
Uses a sample of about _____(#?) people with ________ sampling.
Grounded theory may begin with _______ sampling, progress to _______ ________ sampling, continue until data saturation, and identify ___________ and _________ ______.
20-30 Theoretical sampling Convenience sampling Maximum Variation sampling Confirming and Disconfirming Cases.
Qualitative data is collected through _______, __________, and can include inspecting ________ ________.
1) interviews
2) Observation (participation observation)
3) relevant documents
