A publication may appear in more than one row.
What do these research terms mean?
- Qualitative research
- Examines experiences, meanings, or processes, often through interviews or observations. It can explain how something happens without estimating how common it is.
- Quantitative research
- Uses numerical measurements to describe patterns or test relationships. A relationship between two measurements does not by itself show that one causes the other.
- Systematic review
- Uses a planned, documented method to find and assess research addressing a question. Its conclusions still depend on the included studies and what the search covered.
- Meta-analysis
- Statistically combines results from multiple studies. Combining studies does not remove weaknesses in their design or make unlike populations interchangeable.
- Not classified
- This record has no recognized label in this filter. It does not mean the publication used no method, or that no research exists.
