What Is the Research Design?
A research design is a structured plan or blueprint that guides the entire research process. It outlines how data will be collected, measured, and analyzed to answer the research questions. A well-designed research study ensures that the investigation is systematic, organized, and aligned with its objectives. It provides direction and prevents confusion during data collection and analysis.
What Does the Research Design Answer?
A research design helps address the following questions:
- What method will be used to investigate the research problem?
- Why is this method appropriate for the study?
- How will the researcher collect and analyze data?
- What steps ensure the process is logical and effective?
Example: How It Is Used in This Study
“This study is conducted at San Rafael National High School, a rural public secondary school. It involves a small sample of Grade 12 students who experienced modular learning during and after the COVID-19 pandemic.”
The researcher uses a descriptive research design, which helps describe the students’ academic performance and the challenges they faced in a real-world setting, without manipulating any variables.
Purpose of the Research Design
The purpose of a research design is to:
- Make sure the study answers the research questions effectively.
- Provide a clear and organized structure for conducting the study.
- Ensure the research process stays focused and consistent.
- Help collect reliable and meaningful data related to the topic.
- Support the use of small, context-specific samples.
Types of Research Design
There are several types of research designs, each serving different research goals. The most common types include:
- Descriptive Research Design – focuses on observing and describing a phenomenon as it naturally occurs.
- Experimental Research Design – involves manipulating variables to determine cause-and-effect relationships.
- Correlational Research Design – examines the relationship between two or more variables without manipulation.
- Qualitative Research Design – explores in-depth experiences, behaviors, or meanings through non-numerical data.
- Quantitative Research Design – involves collecting and analyzing numerical data to identify patterns or test hypotheses.
- Mixed-Methods Research Design – combines both qualitative and quantitative approaches for a more comprehensive analysis.
Example:
If a researcher wants to describe how students perform under modular learning without manipulating any factors, they may use a descriptive research design.
