Definition of Quantitative (Fixed) Research Design
According to Burns & Grove,
Quantitative research is a formal, objective, systematic process in which numerical data are used to obtain information about the world.
This research method is used to:
- describe variables
- examine relationships among variables
- determine cause-and-effect interactions between variables
It is a systematic empirical investigation of social phenomena by employing statistical, mathematical or computational techniques. The procedure of measurement is central to quantitative research because it provides the fundamental connection between empirical observation and mathematical expression of quantitative relationships.
Quantitative research is more frequently applied in social sciences such as psychology, economics, sociology, and political science, as compared to in anthropology and history.
Types of Quantitative (Fixed) Research Designs
- Experimental Designs
- Semi-Experimental Designs
- Quasi Experiment
1) Quantitative Research Methods
A) Experimental Designs
- True Experimental Design
- Double-Blind Experiment
Simple Experimental Techniques
- Pretest-Posttest Design
- Control Group
- Randomized Controlled Trials
- Between Subjects Design
- Within Subject Design
Complex Experimental Techniques
- Factorial Design
- Solomon Four-Group Design
- Repeated Measures Design
- Counterbalanced Measures Design
- Matched Subjects Design
- Bayesian Probability
B) Semi-Experimental Designs Quasi-Experimental Design Twin Studies
C) Quasi Experimental Designs
The Quasi Experimental Design is a type of quantitative research design which aims to measure how an intervention impacts the challenges for evaluators and researchers. This is achieved by splitting the subjects into two random groups.
