Research design is a blueprint or systematic approach that discusses how the research will be conducted. It also provides information about the problem statement, hypothesis, and data collection methods and techniques used by a researcher throughout the project.
This article will discuss the characteristics, types, and meaning of research design.
What is Research design?
As mentioned above, a research design is a logical plan containing all project details, from research questions to data collection techniques, from how to interpret data to the hypothesis.
Here are the top goals that effective research design aims to achieve:
- Identify the research problem or purpose of the research
- Review existing projects on the problem
- Prepare research questions
- Define data analysis methods
Here are some unique characteristics of research design:
- Reliable: An effective research design helps in consistently producing reliable results.
- Valid: A research design helps select the right measuring tools.
- Neutral: Research design helps researchers be free from bias.
- Generalized: A good research design draws an outcome that can be applied to a large set of people.
Here are some reasons why you need a research design:
- Reduces inaccuracy
- Eliminates biases
- Makes research efficient and reliable
- Helpful for testing hypothesis
- Provides the right direction for research
- Gives a clear idea of the resources required to complete the research
Elements of a research design
Here are the most important elements of a research design:
- Data collection methodology
- Research Methodology
- Purpose statement
- Measurement of analysis
- Setting for the research study
Types of research design
Research design can be broadly divided into two categories- qualitative and quantitative. Below, we will discuss these two types of research design in detail.
1. Qualitative research
It establishes a relationship between data collected (from primary and secondary sources) and observed by finding answers to how and why. It uses open-ended questions and helps the subjects express their views clearly.
It is ideal for businesses that aim to understand customers’ behavior.
2. Quantitative research
It uses numbers or mathematical calculations to collect actionable insights from the research. This method believes that numbers provide a better perspective for making critical business decisions.
We can further divide the types of research design into five categories.
- Experimental research
This type of research design looks at a problem scientifically by establishing a clear cause and effect of every event.
- Correlational research
Correlation research design establishes a relationship between two related variables. The researcher observes the variables over time and then draws conclusions based on them.
- Descriptive research
Descriptive design is a theory-based research method that describes the research’s primary subject matter. This type of research design uses data collection techniques like natural observation, case studies, and surveys to derive results.
- Diagnostic research
Diagnostic research design strives to explore the reason behind an issue and find solutions to solve it in a structured form.
- Explanatory research
Explanatory research design explores concepts and ideas on a subject to uncover fresh aspects and answer questions like what, how, and why.
