Research Design Flashcards
Strategies, Methods, Validity & Reliability
8 Questions of Research Design
- Research Aim + RQ
- Theoretical Framework
- Operationalisation
- Strategy & Methods
- Sampling Framework
- Validity & Reliability
- Data Analysis
- Conclusion
What is a strategy?
Is the overall procedure followed throughout the research
What is a method?
Data collection
What is a technique?
Data analysis
What is the process of Triangulation?
Researching from multiple angles by using different methods.
It improves validity & reliability.
Types of strategies (5)
Experiment
Survey
Case Study
Desk Research
Mixed Methods
Types of methods (6)
Observation
Interview
Questionnaire
Content Analysis
Second Content Analysis
Meta Analysis
Internal Validity
Whether the researcher is followed the plan/steps throughout the research.
Correct operationalisation
The variables causing the effect NOT the researcher
External Validity
To what extent can the findings be generalised?
*studying a very representative sample increases EV.
Accuracy
To what extent has the researcher measured the variables correctly?
Proper and adequate instruments of measurement.
Replicability
Can the research be replicated by other researchers?
Finding the same results.
Transparency and clarity of all procedures.
“Valid findings are always reliable but reliable findings aren’t always valid”
Issues (3)
Humans can be dishonest
Researching outside the lab endangers validity
Application by human researchers threatens accuracy
How can validity and reliability issues be prevented in an experiment? (5)
Train to prevent bias
Triangulation
Pilot test
Random & Representative samples
Replicability
