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 Researchis 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 ResearchAs listed in Key Elements of A Research Proposal at bcps.org:

The first one is DescriptiveThe second type is CorrelationalThe third is Causal-Comparative or Quasi ExperimentalAnd, the fourth type is "Experimental Bcps.org. (n.d.). 'Key Elements Of A Research Proposal - Quantitative Design'. Web. 7 Sept. 2015.

NOWHow 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

Will there be an intervention or treatment?If, NOTIf, YES then you go for a We ask a series of questions starting fromAsk: Is the primary purpose an examination of relationships?

If, NOT: you go for a If YES, ask:

If, NOT that will be aIf, NOT

If YES, Ask:If, NOT then you go for aIf YES: ask

If, YES-- then you go for an

To recap, we went overWhat 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.
