What is the role of epidemiology in disease prevention?
The Role for Epidemiology in Public Health Analytic epidemiology uses observational or experimental studies to learn about the determinants (i.e., causes) of diseases in populations. These studies are essential to control disease outbreaks or design effective prevention and control programs.
What are the roles of epidemiology?

What is the strongest study design?

What are the qualities of a good research design?
The essential elements of the research design are:
- Accurate purpose statement.
- Techniques to be implemented for collecting and analyzing research.
- The method applied for analyzing collected details.
- Type of research methodology.
- Probable objections for research.
- Settings for the research study.
- Timeline.
How do you define the two design of research qualitative and quantitative?
Quantitative research deals with numbers and statistics, while qualitative research deals with words and meanings. Quantitative methods allow you to test a hypothesis by systematically collecting and analyzing data, while qualitative methods allow you to explore ideas and experiences in depth.
What are the major differences in the methods employed in qualitative and quantitative researches?
| Qualitative Methods | Quantitative Methods |
|---|---|
| Text-based | Number-based |
| More in-depth information on a few cases | Less in-depth but more breadth of information across a large number of cases |
| Unstructured or semi-structured response options | Fixed response options |
| No statistical tests | Statistical tests are used for analysis |
What is the difference between qualitative and quantitative observations?
Qualitative observations are made when you use your senses to observe the results. (Sight, smell, touch, taste and hear.) Quantitative observations are made with instruments such as rulers, balances, graduated cylinders, beakers, and thermometers. These results are measurable.
What is the goal of a qualitative study?

It aims to provide an explicit rendering of the structure, order, and broad patterns found among a group of participants.
When do you use qualitative?

- Understand the feelings, values, and perceptions that underlie and influence behavior.
- Identify customer needs.
