Lecture 3 - Research Design Flashcards
Name the 3 types of research design
Analytical Research
Observational Research
Experimental Research
Order the research design process
- Review available research
- Formulate a question
- Select an appropriate research design
- Collect relevant data
- Interpret findings
- Publish findings
Give 3 examples of Analytical research
Review
Historical Research
Philosophical research
Give 2 examples of observational research
Case study
Survey
What is a cross-sectional design?
Involves comparing different group’s performances over the same period of time
What is a longitudinal design?
Involves comparing the same group’s performances at different time points
What is a problem with observational research?
Difficult to infer causality
What is experimental research?
Involves a direct assessment of how one variable influences another
What are descriptive statistics?
Measures of central tendency, measures of discretion and distribution of scores
What are inferential statistics?
Stats about probability allowing you to make generalisations from samples to populations
What is the independent variable?
The variable the researcher manipulates
What is the dependent variable?
Te variable tha=e researcher measures
Define nominal, ordinal, interval and ratio data
Nominal - Numbers used to distinguish amongst objects without quantitative value
Ordinal - Numbers used to place an order
Interval - Scale on which equal intervals between objects represent equal distances
Ratio - Scale with a true zero point
What is the main difference between a quasi and true experimental design?
True - Random allocation
Quasi - No random allocation
What is a quasi experimental design?
Static group comparison - treatment group compared to control group - no random allocation
Casual comparison - Same as static group but treatments are not under the control of researcher
