Path Analysis
Advanced Statistical Methods
Tracing Cause and Effect Through Systems
Path analysis decomposes relationships among observed variables into direct, indirect, and total effects using path diagrams and structural equations. It reveals how variables influence each other through chains of causation.
- Social science β Quantify how education affects income both directly and through occupational prestige
- Epidemiology β Trace how risk factors contribute to disease through mediating biological pathways
- Organizational behavior β Map how leadership styles influence employee performance through motivation
Path analysis reveals not just whether variables are related, but how they influence each other.
What Is Path Analysis?
Path analysis was developed by Sewall Wright (1920s) as a method for analyzing causal systems in genetics and economics. It remains foundational in psychology, education, and the social sciences.
