This lecture provides a complete and rigorous explanation of the Correlation Coefficient (r), focusing on both computational methodology and economic interpretation.
The session includes:
• Meaning of correlation
• Pearson correlation coefficient formula
• Step-by-step calculation using raw data
• Interpretation of magnitude and direction
• Difference between correlation and regression
• Properties of correlation coefficient
• Relationship between covariance and correlation
• Practical examples in economic and business context
We also clarify common misconceptions such as:
• Does correlation imply causation?
• Why is correlation symmetric but regression is not?
• What does r² actually represent?
This lecture is ideal for students of Economics, Business, Statistics, Data Science, and researchers who want conceptual depth in statistical relationships.
