In research, data can be qualitative or quantitative. Qualitative data is descriptive, often obtained through interviews or observations, providing insights into the ‘why’ and ‘how.’ Quantitative data, on the other hand, is numerical, allowing for statistical analysis and generalizations.

9. Primary vs. Secondary Prevention

When it comes to disease prevention, there are two main approaches. Primary prevention aims to prevent the disease from occurring in the first place, often through measures like vaccinations. Secondary prevention focuses on early detection and treatment to halt the progression of a disease.

International health, on the other hand, refers to health issues specific to different countries or regions.
