Chapter 13: Research Design
Definition:
Basic plan or strategy of research, and the logic behind it, and its possibility and validity to draw general conclusions (Oppenheim, 1999).
Types of research design
Quasi-experimental
Pre-experimental
Experimental
Correlative design
Non-experimental design:
no manipulation of variables by the researcher as the studies is carried out in natural settings
Survey
-Collect information from a particular sample using interviews and/or self-report questionnaires
Advantages:
flexible procedure as data can be collected via various techniques
survey can be used to evaluate theories
random sampling which can represent the characteristics of studied population
Disadvantages
reflect artificial sentiments
reflect inconsistent attitudes of respondents towards the questions
can't enforce participant to provide honest answers
provide tentative answers as respondents' answers often influenced by their interest within the period of study
Cross-sectional study
-collect data from many different individuals at a single point in time
Correlational study
-study of relationship between one or more independent variables and one or more dependent variables
Longitudinal study
-repeated observations of the same variables over short or long periods of time
Case study
-In-depth study which allows researcher to investigate a particular problem in detail and intensive within a certain period of time
Advantages:
able to investigate individuals or programs changes affected by certain circumstances
useful to provide preliminary support to develop research questions and/or hypotheses.
suitable to examine a particular issue that is not thoroughly studied
Grounded theory
-method of developing a theory based on data collected from the field study settings
Action research
-integration of research, action and participation which is used to meet social change agenda
Comparative design
-understand social phenomena by comparing two two or more contrasting cases or situations
Experimental design:
a design in which the researcher actively manipulates aspects of a setting and observes the effects of the manipulation on experimental subjects
Quasi experiments
-researcher is not able to control all aspects while conducting experiments
True experiment
- relies on statistical analysis to approve or disprove a hypothesis
Ethnography
-observing people in their own environment to understand their experiences, perspectives and everyday practices
