I am confused on regression for ANOVA testing. Gertsman (2015), states that regression sum of squares is analogous to the sum of squares between groups in one-way ANOVA, while the residual sum of squares is analogous to the sum of squares within groups in one-way ANOVA. When do we use regression with ANOVA? Do we only use it when data is significantly different?

I found the population regression model confusing on how and when to use it. Figures 14.12 and 14.13 are confusing too on what it is representing. The example given with population regression model does not makes sense and I would greatly appreciate if someone could help me understand the concept better!
