Line of Best Fit (HSC SSCE Mathematics Standard): Quizzes

A line approximating linear relationship

Prediction within existing data range

Vertical distance from point to line

Sum of all squared residuals

$m = r \times \frac{s_y}{s_x}$

$c = \bar{y} - m\bar{x}$

$(\bar{x}, \bar{y})$

Between $-1$ and $+1$

So negatives don't cancel out

Strong positive linear association
