4. Correlational research design
5. Longitudinal research design
6. Cross-sectional research design
7. Case study research design
8. Ethnographic research design
9. Action research design
10. Mixed methods research design

1. Observational Research
- Cross-sectional: Collects data at one point in time.
- Longitudinal: Collects data over an extended period, either:
- Prospective: Follows participants forward in time.
- Retrospective: Collects data about past events.

2. Experimental Research
- True experiment: Randomly assigns participants to one or more experimental groups and a control group.
- Quasi-experiment: Does not have true random assignment, but may use other methods (e.g., matching, time series) to control for confounding variables.

3. Mixed-Methods Research
- Combines qualitative and quantitative methods to gather and analyze data.

4. Qualitative Research
- Focuses on the experiences, perspectives, and meanings of individuals or groups.
- Methods include:
- Interviews
- Focus groups
- Ethnography
- Content analysis

5. Quantitative Research
- Collects and analyzes numerical data to test hypotheses or answer research questions.
- Methods include:
- Surveys
- Experiments
- Statistical analysis

6. Action Research
- Involves researchers and practitioners working together to improve a situation or problem.

7. Participatory Research
- Involves researchers and participants collaborating as equal partners in the research process.

8. Case Study Research
- In-depth investigation of a single individual, group, or organization.

9. Meta-Analysis
- Statistical analysis that combines the results of multiple studies.

10. Survey Research
- Collects data from a sample of individuals through self-report questionnaires.

11. Correlational Research
- Examines the relationship between two or more variables without manipulating them.
