According to the Gujarati methodology , researchers follow these eight steps:

| Module | Gujarati Chapter | Key PPT Visuals | | :--- | :--- | :--- | | | 1-3 | Scatter plots, OLS regression line, residuals | | Multiple Regression | 4-7 | Matrix notation, R-squared vs. Adjusted R-squared | | Functional Forms | 6 | Log-linear, log-log, semi-log graphs | | Dummy Variables | 9 | Seasonal patterns, structural breaks | | Panel Data & MLE | 16-17 (applied) | Fixed vs. Random effects tables |

estimators, trying to find the line that best fit the scattered dots of his data. He wrestled with Multicollinearity

A well-crafted is not just a study crutch; it is a conceptual roadmap. Gujarati’s genius is making the leap from economic theory to quantitative proof feel logical. Your PPT should mirror that logic: start with a problem (e.g., "Does education raise wages?"), apply OLS, check assumptions, and interpret results.
