Another cornerstone of Volume 7 is the deep dive into linear regression and the coefficient of determination. Moving beyond simple algebra, statistics looks at how strongly two variables are related and whether one can reliably predict the other. Gibson’s lectures focus on the method of least squares to find the line of best fit and how to interpret the slope in a real-world context. This section empowers students to build predictive models, a skill that serves as the bedrock for modern machine learning and data analytics. Pedagogical Strategy: The "Math Tutor DVD" Method

| Mistake | Correction | |---------|-------------| | Using t-test for proportions | Use z-test for proportions | | Forgetting continuity correction | Not needed for large n (n>30) | | Using O instead of (O-E)²/E | Square before dividing | | Using raw counts in chi-square | Must use frequencies, not percentages | | Expecting chi-square to work with small expected counts | Use Fisher’s exact test if conditions fail |

: Primarily aimed at college-level students or those taking AP Statistics , as the topics move beyond general high school math.
