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.
