What are the types quantitative Research Designed?
There are four types of quantitative Research Designed.
Descriptive research
Correlational research
Causal-comparative/quasi experimental research
Experimental research
a. Descriptive research
Descriptive research seeks to describe the current status of an identified variable. These research projects are designed to provide systematic information about a phenomenon. The researcher usually begin with research question, but is likely to develop hypotheses after collecting data.
Example : –
A description of the attitudes of scientists regarding global warming.
A description of how Higher secondary school students spend their time during summer vacation.
b. Correlational research
Correlational research attempts to determine the extent of a relationship between two or more variables using statistical data. In this type of design, relationships between and among a number of facts are sought and interpreted.
Example:
Correlation between the Research Publication and Citations of Computer Science Faculty member
Correlations between the income and expense of Farmers
Or demand and price correlation of the non-wheat producing country
c. Causal-comparative/quasi experimental research
Causal-comparative/quasi experimental research attempts to establish cause effect relationships among the variables. These types of design are very similar to true experiments, but with some key differences.
- In a true experiment, participants are randomly assigned to either the treatment or the control group, whereas they are not assigned randomly in a quasi-experiment
- In a quasi-experiment, the control and treatment groups differ not only in terms of the experimental treatment they receive, but also in other, often unknown or unknowable, ways. Thus, the researcher must try to statistically control for as many of these differences as possible
- Because control is lacking in quasi-experiments, there may be several “rival hypotheses” competing with the experimental manipulation as explanations for observed result.
Example: –
The effect of taking multivitamins on Colleges students’ absenteeism.
The effect of part-time employment on the results achievement of high school students.
d. Experimental research/True Experimental
Experimental research, often called true experimentation, uses the scientific method to establish the cause-effect relationship among a group of variables that make up a study. The true experiment is often thought of as a laboratory study, but this is not always the case; a laboratory setting has nothing to do with it.
Example: –
A comparison of the effect of personalized instruction vs. traditional instruction on computational skill
The effect of teaching with a cooperative group strategy or a traditional lecture approach on students’ achievement.
