Quantitative research is a systematic investigation of data relationships aimed at prediction, utilizing mathematical models and measurements. There are four main types of quantitative research: descriptive, correlational, causal-comparative (or quasi-experimental), and experimental, each with specific applications. A decision-making process is outlined for determining the appropriate research design based on the study's purpose and whether intervention is involved.
Quantitative research design an overview
- 1. Quantitative Research Design Myrene Magabo Penn State University
- 2. What is Quantitative Research? Cohen, Manion and Morrison, in their book published in 2004 define quantitative research as a systematic and scientific investigation of data and their relationships.
- 3. As many of us already may already know, the goal of quantitative research is prediction.
- 4. The objective of Quantitative Research is to develop and employ mathematical models, theories and hypotheses pertaining to natural phenomena. Measuring is key in quantitative research. It is because it shows the relationship between data and observation.
- 5. There are four types of Quantitative Research As listed in “Key Elements of A Research Proposal” at bcps.org: 1. The first one is “Descriptive” 2. The second type is “Correlational” 3. The third is “Causal-Comparative or Quasi – Experimental” 4. And, the fourth type is "Experimental Bcps.org. (n.d.). 'Key Elements Of A Research Proposal - Quantitative Design'. Web. 7 Sept. 2015.
- 6. NOW How do we decide what to use for our Quantitative Research? When should we go descriptive? When do we go for correlational research? When do we conduct a Causal-Comparative or Quasi – Experimental Research? When do we go for experimental research? Let me show you how the recommended decision-making process goes
- 7. Will there be an intervention or treatment? If, NOT If, YES then you go for a We ask a series of questions starting from Ask: Is the primary purpose an examination of relationships? If, NOT: you go for a If YES, ask: If, NOT– that will be a If, NOT If YES, Ask: If, NOT then you go for a If YES: ask If, YES-- then you go for an Ex Post Facto Design
- 8. To recap, we went over What is quantitative research; What are the four types of quantitative research; and, The proper decision-making process that must be followed in choosing which type of design we will use.
- 9. Each of the four types of quantitative research design may have its distinct uses and possibly its advantages and disadvantages. And all these can be discussed in another presentation. For questions or comments E-mail me at: mam89@psu.edu
