It involves detailed study of a small sample or group.
In this module, the four approaches to quantitative research are described and examples are provided. List and explain the four approaches to quantitative research. Provide an example of each method.
Describe how to identify the appropriate approach for a particular research problem.
There are four main types of quantitative research designs: The differences between the four types primarily relates to the degree the researcher designs for control of the variables in the experiment.
Following is a brief description of each type of quantitative research design, as well as chart comparing and contrasting the approaches. A Descriptive Design seeks to describe the current status of a variable or phenomenon.
The researcher does not begin with a hypothesis, but typically develops one after the data is collected. Data collection is mostly observational in nature.
A Correlational Design explores the relationship between variables using statistical analyses. However, it does not look for cause and effect and therefore, is also mostly observational in terms of data collection.
A Quasi-Experimental Design often referred to as Causal-Comparative seeks to establish a cause-effect relationship between two or more variables. The researcher does not assign groups and does not manipulate the independent variable.
Control groups are identified and exposed to the variable. Results are compared with results from groups not exposed to the variable. Experimental Designs, often called true experimentation, use the scientific method to establish cause-effect relationship among a group of variables in a research study.
Researchers make an effort to control for all variables except the one being manipulated the independent variable. The effects of the independent variable on the dependent variable are collected and analyzed for a relationship. When deciding on the appropriate approach, the Decision Tree from Ebling Library may be helpful.
The following video, Quantitative Research Designs, further describes the differences between quantitative research approaches and offers tips on how to decide on methodology. Qualitative and quantitative approaches. Qualitative, quantitative, and mixed methods approaches.

Johnson, Daniel R., "A Quantitative Study of Teacher Perceptions of Professional Learning Communities' Context, Process, and Content" ().
I thank my parents for the example and work ethic that they provided for me. CHAPTER THREE - Methodology Research Design Context of the Study Participants Instrumentation Data . List and explain the four approaches to quantitative research.
Provide an example of each method. Describe how to identify the appropriate approach for a particular research problem. There are four main types of quantitative research designs: descriptive, correlational, quasi-experimental and experimental. Analyzing the Data In the above examples of quantitative research methods, one can see that almost any type of focus group, questionnaire or survey can be utilized to “fix" the problem.
These methods show actual number results, meaning the project can focus on how many to produce and which kind will sell best.

Example Quantitative Research Question What is the relationship between stress and achievement? Design. Methodology Type of Research The type of research that will be used in this study is qualitative research and quantitative research. Qualitative researchers aim to gather an in-depth understanding of human behavior and the reasons that govern such behavior.
