What Is the Purpose of the Research Design?


Research design, as a framework of research, has its purpose, methods, and types. Providing a plan of the research between independent and dependent variables, considering the cause and effect which is evoked by these variables is a purpose of research design.

Generally speaking, this purpose can be executed in different forms and types for better results of the research. The methods of the research design can vary from:

  • Observations
  • Surveys
  • Interviews
  • Experiments
  • Archival studies
  • Mixed methods

As we explain here, the methods of the research design are always picked up and back up the purpose and the goals of the research.

Main Goals of Research Design

  1. The main goal of the research design is for a researcher to make sure that the conclusions he or she made are justified. It means that the research has to confirm the theory of the whole process. Sometimes the results of the research can overlap the existing archives or documents on the topic, but the insights are what the whole process is about.
  2. The other main purpose of the research design is to broaden your understanding of the topic. To extend the consciousness of a researcher to the places, groups, and settings.
  3. Allows you to provide an accurate understanding and explanation of the phenomenon or the topic you are working on.

The fact is that you can not accomplish all these three goals at a time, but you can try to do that by using multi-stage design in your study, which is also known as multi-stage sampling.

Formats of Research Design

The format of the research design should always be compared with its purpose. Here is our list of the formats to choose from for your research.

General Structure and Writing Style

The format of the research should answer all the questions of the statement accurately, that's why collecting data, you have to choose specific evidence, which will show you the differences or bugs between the variables. Before making research, think of what information you will need and how you're going to use that. Without it, you can get lost.

Action Research Design

When the understanding of the problem is developed and the plans are made for interventional strategy, action research design helps to bring the deviance to the surface. When the intervention is made, the observation is bookmarked. After, the results of the action can be compared to the ones without it.

Case Study Design

A case study is learning a particular problem comparing to the custom statistical survey. To narrow down the researchable subjects out of the broad samples, the researchers use this format. This one is also cool when there is a need to check if the theory applies to the real-world problem.

Causal Design

If the A then B, that's how we can explain simply the model of the causal design. Comparing two or more variables, a researcher can understand the effect of the first to the other. The effect can be measured as from the point of A as long as form the point of the B variable.

Cohort Design

More often used in medical studies, but now is gaining popularity in social science. Based on the quantitative framework, where a researcher makes notes on the statistical occurrence between a subgroup, joined with the same features that are related to the study topic, rather than analyzing mathematical occurring within the custom group. Observation is the main method of data gathering of the cohort design.

Remember that the step by step approach in studying research is the one that will lead you to the basics of the research. Also, you can try to implement other research formats from multiple spheres and try more mixed methods of research. Stay tuned!
