How is Data Analyzed in Epidemiological Studies?

The analysis of epidemiological data involves several steps and techniques:
- Descriptive Statistics: These are used to summarize the data and include measures such as mean, median, mode, incidence, and prevalence.
- Inferential Statistics: These help in making inferences about the population based on sample data. Techniques include regression analysis, hypothesis testing, and confidence intervals.
- Multivariate Analysis: This is used to understand the relationship between several variables simultaneously. Methods include logistic regression, Cox proportional hazards model, and factor analysis.
