• 1 Use Least-squqres to fit a line to the data

• 2 Clculate $R^{2}$

• 3 Calculate a $p-value$ for $R^{2}$

The regression equation: $y=a+bx$

• Dependent variable: $y$:
• Independent variable: $x$:
• Slope: $b=r{\frac {S_{y}}{S_{x}}}$

The slope is the amount of change in units of $y$ for each unitchange in $x$.

• $y$ intercept: $a={\bar {y}}-b{\bar {x}}$:
