week 6 Flashcards
thematic coding
- Begin with as few pre-determined ideas as possible
- Coding is shaped by interpretation of the data (what does this mean?)
- Characterised by different types and levels of codes
- Categories of data are created and refined through constant comparison to develop themes
- Analysis and data collection are iterative
memo writing
Make field notes/memos throughout the entire data collection:
i Process of data collection - reflect on what worked or didn’t work
analysis considerations
chronology key events various settings people process issues
developing themes
code
category
theme
Name and describe the three steps in grounded theory data analysis.**
- Initial/Open coding: a literal line-by-line reading andi nterpretation of salient categories
- Axial Coding: grouping of the first order, or open codes into coherent categories and sub-categories
This involves synthesising the most significant/frequently used words/experiences into formal codes to create categories/ conceptual similarities. - Selective Coding: selecting and validating major categories that outline relationships and interactions between the codes
constant comparison
- different people views, actions etc
- data from the same individual at different points in time
- incident by incident,
- data categories,
- category with other categories.
consensus coding
Measure of reliability of coding
Two coders independently code data in same way
Way of assessing validity or accuracy in data
Improves consistency and quality of analysis
Have two coders or team code same few interviews Come to consensus on codes/revise definitions
Name and describe content analysis**
The objective of qualitative content analysis is to systematically transform a large amount of text into a highly organised and concise summary of key results (summative/quantitative
Content analysis is the procedure for the categorisation of verbal or behavioural data for the purpose of classification, summarization and tabulation and abstraction
inductive content analysis steps
- open coding: creating heads while reading text
- creating categories: grouping headings into higher order headings
- abstract themes
deductive content analysis
- Often used in cases where the researcher wishes to retest existing data in a new context
- The researcher typically begins the analysis, using the pre-existing categories (analysis matrix) imposed by the theory or previous research findings, which is clearly the instance of deduction.
challenges with qualitative analysis
unexpecting challenging
time consuming
What is the difference between a ‘target population’ and an ‘accessible population’?*
Target population – the population to which the researcher ideally wants to generalise study results to
Accessible population – the population to which the researcher has access to (e.g., participants from a specific region or patients from one clinical site)
- In the context of quantitative sampling, what does ‘representation’ refer to?**
the extent to which a sample or subgroup is representative of the population
Demographic characteristics: age, gender, ethnicity
• Personal characteristics
• Specific traits
• Diagnosis / clinical presentation
• Accessibility to participants
• Ethical issues (vulnerable group? Children?)
whats sample error
- The change occurance that a randomly selected sample is not representative of the population due to errors inherent in the sampling techniquw
- Random nature of errors
- Controlled by selecting large samples that are representative of the population (eg using government census data to ensure representation)
whats sample bias
- Some aspect of the researchs sampling design creates bias in the ata
- Non random nature of errors
- Controlled by being aware of sources of sampling bias and avoiding them
- Example; surveying only students who attend additional tutorial session in a specific tasks.
