What is the primary purpose of descriptive research design?
What is the primary purpose of descriptive research design?
To describe characteristics of a population or phenomenon being studied.
What is the key difference between cross-sectional design and longitudinal design?
What is the key difference between cross-sectional design and longitudinal design?
Cross-sectional design collects data from a sample at one point in time, whereas longitudinal design collects data from the same sample over a period of time.
What is the advantage of using a longitudinal design?

Study Notes
Research Design
- Research can be informal and unstructured.
Descriptive Research Design
- Used to describe characteristics of a population or phenomenon being studied.
- Helps measure the relationship between two variables.
- Two types: Cross-sectional design and Longitudinal design.
Cross-sectional Design
- Collecting data from a given sample of population elements only once.
- Two types: Single cross-sectional design and Multiple cross-sectional design.
- Single cross-sectional design: One sample of respondents, information obtained once.
- Multiple cross-sectional design: Two or more samples of respondents, data obtained once from each sample.
- Types of Multiple cross-sectional design: Cohort analysis.
- Cohort analysis: A series of surveys conducted at appropriate intervals, focusing on a group of respondents who experience the same event within the same time interval.
Longitudinal Design
- The same sample remains over time, providing a series of pictures that give a deeper understanding of the situation and changes over time.
- Advantages: Ability to detect change at the individual level, uses panels, allows for large amounts of data to be collected.
- Disadvantages: Can be time-consuming, data can be inaccurate.
Causal Research Design
- Designed to determine whether one or more variables causes or affects one or more outcome variables.
- Objective: Determine causes and effect relationships.
Exploratory vs. Conclusive Research
- Exploratory Research:
- Objective: Offer insight and understanding of the problem investigated.
- Characteristics: Information is defined loosely, flexible research process, unstructured, small sample size, data analysis is qualitative.
- Findings: Tentative, requires a follow-up exploratory or conclusive research.
- Conclusive Research:
- Objective: Focuses on hypotheses testing and examining the relationship.
- Characteristics: Information is clearly defined, structured and formal research process, large sample size, data analysis is quantitative.
- Findings: Conclusive, used in decision making.
Basic Research Design
- Exploratory Research Design:
- Objective: Discover ideas.
- Characteristics: Flexible, versatile, front-end of total research, marked by prior formulation of specific hypothesis.
- Methods: Expert survey, pilot survey, case studies, secondary data (qualitative analysis).
- Descriptive Research Design:
- Objective: Describe the market characteristics or functions.
- Characteristics: Preplanned and structured design.
- Methods: Surveys, panels, observation, and other data.
- Causal Research Design:
- Objective: Determine causes and effect relations.
- Characteristics: Manipulation of one or more independent variables, measure the effect on dependent variables, control of mediating variables.
- Methods: Experiments.
Exploratory Research Design
- Conducted for a research problem when the researcher has no past data or only few studies for reference.
- Helps with in-depth search of information where little is known about the role.
