Pay attention to the subscripts and these are the keys to understanding this material.

Typo at 2:30: The equation should be \( \sum_i \sum_j \sum_k \sum_l (\bar{Y}_{i \cdot\cdot\cdot} - \bar{Y}_{\cdot\cdot\cdot\cdot} )^2 = bcn \sum_i (\bar{Y}_{i \cdot\cdot\cdot} - \bar{Y}_{\cdot\cdot\cdot\cdot} )^2 \)
