Type of data analysis related to grounded theory. All data sources are compared and core codes emerge

102
Q

How are substantive and theoretical codes of grounded theory data analysis related?

A

The substance of the topic under study is conceptualized throughout substantive codes, while theoretical codes provide insight into how substantive codes are related to one another

103

112
Q

A 
Credibility 
Dependability 
Confirmability
Transferability 
\+Authenticity
113
Q

What is credibility?

A

Confidence in the truth of the data and interpretations of them

(must carry out a study in a way that enhances believability of the findings and take steps to demonstrate credibility in research reports- audit trails etc

114
Q

What is dependability?

A

The stability (reliability) of data over time and conditions

Credibility can not be obtained in the absence of dependability

115
Q

What is confirmability?

A

Accuracy/congruency between participants.

Ensures that the data represents the information participants provided and that interpretations were not invented by researchers

116
Q

What is transferability?

A

The extent to which findings can be transferred to or have applicability in other settings or groups

‘Fitting-ness’

117
Q

What is authenticity?

A

Extent to which researchers fairly and faithfully show a range of realities

118
Q

What is prolonged engagement vs persistent observation?

A

Prolonged engagement is important in establishing credibility; it is the investment of sufficient time data collecting and immersing oneself in data to provide rich, detailed information.

Persistent observation refers to the researchers’ focus on the characteristics or aspects of a situation/convo that are relevant to the phenomena being studied

119
Q

What do data and method triangulation refer to?

A

Data triangulation is the use of multiple data sources to validate conclusions. Method triangulation is the use of multiple methods in data collection.

(time- collecting data on the same phenomena at diff times; space- same phenomena at multiple sites; person- collecting data from multiple levels of people)

120
Q

What is meant to enhance quality and rigor and is described as two or more investigators carrying out independent coding and data analysis?

A

Investigator triangulation

121
Q

What is member checking?

A

Researchers go back to participants to check interpretations. This can enhance a study’s credibility

122
Q

When researchers used competing theories or hypotheses in analyzing and interpreting data this is called:

A

Theory triangulation

123
Q

What is a negative case analysis?

A

When researchers search for cases that appear to disconfirm earlier hypotheses and revise their interpretations as necessary

124
Q

What assumption to qualitative studies make in regards to reality?

A

Multiple realities exist

125
Q

What are quasi-statistics?

A

Used in a qualitative study, they tabulate frequency of themes or insights in the data
