Research Design
Research Design
The overall concept or strategy to logically assemble the components of a study, ensuring the research problem is addressed.
Non-Experimental Design
Non-Experimental Design
A research design where the researcher observes phenomena as they naturally occur, without introducing external variables or manipulating the setting.
Descriptive Research Design
Descriptive Research Design
Aims to observe, describe, and document aspects of a situation naturally; can serve as a starting point for hypothesis generation or theory development.

Study Notes
- Planning the research design is essential before writing a research paper
- Research design is the overall strategy to logically assemble the study's components
- The research design ensures the research problem is appropriately addressed
- The type of research design is determined by the research problem and questions
- Researchers should choose the correct research design before gathering relevant information
- Reviewing and synthesizing literature from studies using similar research designs is helpful
Non-Experimental Design
- Suitable for research topics that do not involve experimentation
- Involves observing phenomena as they naturally occur without introducing external variables
- Variables are not deliberately manipulated, and the setting is not controlled
- Data is collected without making changes or introducing treatments
- Also known as Descriptive Research Design
Descriptive Research Design
- It describes and documents aspects of a situation as it naturally occurs
- It serves as a starting point for hypothesis generation or theory development
Types of Descriptive Design
- Survey: gathers information from groups by selecting and studying samples chosen from a population
- Used to see a general picture of the population under investigation in terms of their social and economic characteristics, opinions, and knowledge about the behavior towards a certain phenomenon
- Correlational: aims to find out the direction, associations, and/or relationships between different variables or groups of respondents under study
- Ex-Post Facto or Causal-Comparative: derives conclusions from observations and manifestations that already occurred in the past and compares them to some dependent variables
- Discusses why and how a phenomenon occurs
- Example: examining the effects of weight on stress-coping levels in adults by separating subjects into underweight, normal, and overweight groups
- Example: examining the effect of homeschooling on the social skills of adolescents
- Comparative: involves comparing and contrasting two or more samples of study subjects on one or more variables, often at a single point in time
- This design is used to compare two distinct groups based on selected attributes such as knowledge level, perceptions, attitudes, physical or psychological symptoms
- Example: examining the Health Problems among Rural and Urban People in Ilocos Region, Philippines
- Normative: describes the norm level of characteristics for a given behavior
- Example: describing high school students' study habits using a range of scores
- Evaluative: used to determine what has happened during a given activity or in an institution
- Determines if a given program is working, an institution is successful according to the goals set for it, or the original intent was successfully attained
- Example: assessing the effectiveness of teaching or the deployment of a curriculum
- Methodological: the implementation of a variety of methodologies forms a critical part of achieving the goal of developing a scale matched approach, where data from different disciplines can be integrated
