In research, selecting an appropriate design, location, and sample is essential. The research design outlines how data will be collected and analyzed, the locale specifies where the study will be conducted, and respondents are those who will provide the data. These choices are vital for producing effective and credible research.
Lesson objectives
At the end of the lesson, you should be able to:
A research design is the plan or framework used to conduct a research study. It involves outlining the overall approach and methods that will be used to collect and analyze data in order to answer research questions or test hypotheses. (Singh, 2023)
The research design refers to the overall strategy that you choose to integrate the different components of the study in a coherent and logical way, thereby, ensuring you will effectively address the research problem; it constitutes the blueprint for the collection, measurement, and analysis of data. (Kirshenblatt-Gimblett, 2006)
A research design is essential to systematically investigate, understand, and interpret phenomena of interest. Below are the different types of research designs.
Broadly, research design types can be divided into qualitative and quantitative research.
Qualitative research is subjective and exploratory. It determines relationships between collected data and observations. It is usually carried out through interviews with open-ended questions, observations that are described in words, etc.
| Type of Design | Purpose and Characteristics | Examples |
|---|---|---|
| Case study |
|
“Resilience in Crisis: A Case Study of Community Response to a Natural Disaster” |
| Ethnography |
|
A Study on “Poverty affects schooling on children” |
| Grounded theory |
|
A study on how people adopt an app by conducting interviews, analyzing the data for patterns, and using those patterns to develop a theory. |
| Phenomenology |
|
“A Journey of Career Choices: A Phenomenological Study of Senior High School Students' Decision-Making Process for Future Careers” |
Qualitative Research Design
Quantitative research is objective and employs statistical approaches. It establishes the cause-and-effect relationship among variables using different statistical and computational methods. This type of research is usually done using surveys and experiments.
| Type of Design | Purpose and characteristics | Examples |
|---|---|---|
| Experimental |
|
Determining the efficacy of a new vaccine plan for influenza. |
| Quasi-experimental |
|
Measurement of learners’ performance in a college on weekly basis and then introducing a new teaching technique. Then again measuring in a weekly basis. |
| Correlational |
|
A study on correlation between time spent watching crime shows and aggressive behavior in teenagers. |
| Descriptive |
|
A study on the different income levels of people who use nutritional supplements regularly. |
Quantitative Research Design
| Design Type | Variants | Timing | Weighting | Mixing | Notation |
|---|---|---|---|---|---|
| Triangulation |
|
Concurrent: quantitative and qualitative at same time | Usually equal | Merge the data during the interpretation or analysis | QUAN + QUAL |
| Embedded |
|
Concurrent or sequential | Unequal | Embed one type of data within a larger design using the other type of data | QUAN(qual) Or QUAL(quan) |
| Explanatory |
|
Sequential: Quantitative followed by qualitative | Usually quantitative | Connect the data between the two phases | QUAN → qual |
| Exploratory |
|
Sequential: Qualitative followed by quantitative | Usually qualitative | Connect the data between two phases | QUAL → quan |
Moreover, Creswell’s (2013) mixed methods embedded intervention research design will be used. The quantitative data from the pretest and posttest and the qualitative data from the interviews will be collected and analyzed simultaneously.
The quantitative component will measure the increase in knowledge of students through pretests and posttests conducted before and after playing the board games. The qualitative component will involve interviews with participants to gather detailed feedback on the game-playing experience, perceived effectiveness of the board games in conveying crucial safety information, and personal feelings of preparedness.
The results will be combined to gain an in-depth understanding of the efficacy of the intervention, “Disaster Risk Reduction Board Games.”
In the context of research, a respondent refers to the individual who participates in a research by completing surveys, questionnaires, interviews, or other data collection tools.
When conducting academic research, selecting the right participants is very important. The choice of participants has a profound impact on the quality and validity of the findings obtained. Ensuring that the selected individuals match the characteristics of ideal respondents contributes to the overall success of the research project.
