Statistical Models

When a scatterplot is created between two variables, we describe the highest and lowest x-variables as the upper and lower poles respectively. If a line of best fit has been drawn, then predictions can be made for one variable given the other.

- If we predict a value that occurs in between the lower and upper poles, then we say we are
**interpolating**between the poles. - If we predict a value that occurs outside of either the lower or upper pole, then we say we are
**extrapolating**outside the poles.
