Study Notes
Introduction
- Research papers should include background information and a clear statement of the problem.
- The research problem should explain the fundamental reasons for the research.
- Figure legends should cite references.
- The dependent (measured) variable is displayed on the Y-axis, while the independent (categorical) variable is displayed on the X-axis.
- Prevalence studies measure all cases of a disease, not just new cases (incidence).
- Prevalence studies are not suitable for studying rare, highly fatal, or short-duration diseases (acute diseases).
Subjects and Methods
- For research involving a confined population, all subjects can be included.
- For studies with a large target population, a representative sample should be used.
- Continuous quantitative variables are measured using scales.
- Discrete quantitative variables are obtained by counting.
- Histograms are the best way to visualize continuous quantitative variables, such as weight, height, blood pressure, and blood sugar.
- Pie charts are used to display categorical data.
- Pie charts are circular diagrams divided into segments, where each segment represents a different category.
