Choosing an Experimental Design¶

Contents of Section 3

This section describes in detail the process of choosing an experimental design to obtain the results you need. The basic designs an engineer needs to know about are described in detail.

Note that this section describes the basic designs used for most engineering and scientific applications

• Set objectives
• Select process variables and levels
• Select experimental design
• Completely randomized designs
• Randomized block designs
• Full factorial designs
• Fractional factorial designs
• Plackett-Burman designs
• Response surface designs
• Adding center points
• Improving fractional design resolution
• Three-level full factorial designs
• Three-level, mixed level and fractional factorial designs
