The analysis of quantitative data involves several steps:
1. Descriptive Statistics: These are used to summarize and describe the main features of a data set. Common measures include the mean, median, mode, and standard deviation. 2. Inferential Statistics: These techniques allow epidemiologists to make inferences about a population based on a sample. Methods include hypothesis testing, confidence intervals, and regression analysis. 3. Modeling: Advanced statistical models, such as logistic regression or Cox proportional hazards models, are used to explore the relationship between multiple variables and health outcomes.
