Conclusive research design, as the name implies, is applied to generate findings that are practically useful in reaching conclusions or decision-making. Conclusive research design usually involves the application of quantitative methods of data collection and data analysis. Moreover, conclusive studies tend to be deductive in nature and research objectives in these types of studies are achieved via testing hypotheses.
The table below illustrates the main differences between conclusive and exploratory research design:
|Objectives||To test hypothesis and relationships||To get insights and understanding|
|Information needs a clearly defined Research process is formal and structured
Large representative sample
Data analysis is quantitative
|Information needs are loosely defined
Research process is unstructured and flexible
Small, non-representative sample
Primary data analysis is qualitative
|Outcome||Findings used as input to decision making||Generally followed by further exploratory conclusive research|
It has to be noted that “conclusive research is more likely to use statistical tests, advanced analytical techniques, and larger sample sizes, compared with exploratory studies. Conclusive research is more likely to use quantitative, rather than qualitative techniques”.
Descriptive research is used to describe some functions or characteristics of phenomenon and can be further divided into the following groups:
- Case study;
- Case series study;
- Cross-sectional study;
- Longitudinal study;
- Retrospective study.
Causal research, on the other hand, is used to research cause and affect relationships. Two popular research methods for causal studies are experimental and quasi-experimental studies…
