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.
As many of us already may already know, the goal of quantitative research is prediction.
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.
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.
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?
We ask a series of questions starting from: Will there be intervention or treatment? If not, Ask: Is the primary purpose an examination of relationships? If NOT, then you go descriptive. If YES, ask: Will the sample be studied as a single group? If YES, then you go for a co-relational design; if not--then that would be a descriptive design.
If YES, there will be an intervention, ASK: Is the treatment tightly controlled by the researcher? If not, then you go for a quasi-experimental design [Ex Post Facto Design]. If YES, there will be an intervention, ASK: Will a randomly selected control group be used? If YES, then you go for an experimental design. If not, then that will be a quasi-experimental design.
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.
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.
