QUIZ 3: Chapter 21 Qualitative Sampling Flashcards
Which is NOT a feature of qualitative sampling?
1- Samples tend to be small & studied intensively
2-Participants are selected randomly
3-Sample members aren’t pre-specified
4-Sample selection is driven by conceptual ideas rather than for representativeness
2-Participants are selected randomly
*Participants are NOT selected randomly
Name the type of sampling.
*Volunteer sample, most easy & economical, not preferred approach even in qualitative study
Convenience sampling
Name the type of sampling.
*also used in quantitative sampling, asking early informants to refer other study participants, practical & cost efficient, establishes trust, eventual sample may be restricted
Snowball sampling
Name the type of sampling.
*select cases that will most benefit the study, several diverse approaches to meet conceptual & substantive needs of research, sampling for representativeness or comparative value
Purposive sampling
Name the type of sampling.
- researcher selected participants who are alike with respect to a certain variable
- deliberately reduces variations & allows for more focused inquiry
- useful for focus groups
Purposive: Homogeneous Sampling
Name the type of sampling.
- select cases that illustrate typical, average, normal
- can help researchers understand key aspects of phenomenon as they advance under ordinary circumstances
Purposive: Typical Case Sampling
Name the type of sampling.
- expansion of typical case sampling
- selection of average, above average, & below average
- close to maximum variation sampling but done along a single dimension
- each stratum represent fairly homogenous sample
Purposive: Stratified Purposive Sampling
Name the type of sampling.
- AKA outlier sampling
- selection from cases that at least on the surface seem like exceptions to the rule
- underlying assumption that extreme are rich information because they are special
Purposive: Extreme (Deviant) Case Sampling
Name the type of sampling.
- select rich cases that offer strong examples of the phenomenon of interest
- similar to extreme case but with less emphasis
- information-rich cases
- usually coupled with another sampling method
Purposive: Intensity Sampling
Name the type of sampling.
- selecting cases based on recommendation of an expert of key informant
- useful when researchers have little information about how to best proceed with sampling
- must rely on recommendations from others
Purposive: Reputational Sampling
Name the type of sampling.
- good method to use when funds are limited
- research team identifies dimensions that make a case critical
- involves selecting important cases regarding the phenomenon of interest
Purposive: Critical Case Sampling
Name the type of sampling.
- can provide an important qualitative aspect to quantitative data
- involves selecting cases that meet a predetermined criterion of importance
Purposive: Criterion Sampling
Name the type of sampling.
- purposefully selecting people with wide range of variation on dimension of interest
- diverse perspective and backgrounds to invite enrichments of & challenges to emerging conceptualizations
- any common patterns emerging despite diversity of sample are of particular value in capturing core experiences
Purposive: Maximum Variation Sampling
Name the type of sampling.
- important in grounded theory research
- requires researcher to have sufficient data to be able to generate and create a theoretical explanation of what is happening in the situation
- researchers gather more and more data until theory remains unchanged
Theoretical Sampling
Describe qualitative data saturation.
- guiding principle in sampling of qualitative data
- sampling to the point where no new info is being obtained and redundancy is achieved
- occurs until there is a signal that little is needed to continue process
