What points can I use in a designed experiment?

The following table describes different types of points in a designed experiment:

Point	Screening Designs	Factorial Designs	Response Surface Designs	Mixture Designs
0	center point	center point	center point	centroid
1	corner point	corner point (cube point)	cube point (corner point)	vertex
-1	-	-	axial point	axial point
2	edge midpoint*	-	edge midpoint**	edge midpoint (double blend)
3	-	-	-	triple blend***

*Applies only to definitive screening designs.

**Applies only to Box-Behnken designs.

***In mixture designs, the point type increases naturally (or respectively) with higher order blends.
