Factorial Experimental Design Slideshare. K factors all at two levels The two levels are usually called low and high they could be. Tables for Statistical Quality Control defines fractional factorial design in the following way.
A factorial experiment in which only an adequately chosen fraction of the treatment combinations required for the complete factorial experiment is selected to be runA carefully chosen fraction of the runs. Common applications of 2k factorial designs and the fractional factorial designs in Section 5 of the course notes include the following. Quasi-experiments include a comparison of at least two levels of an independent variable but the manipulation is not always under the experimenters control.
Quasi-experimental designs resemble experiments but are weak on some of the characteristics.
A full factorial design may also be called a fully crossed design. 1 Chapter 5 Introduction to Factorial Designs 2. Jun 29 2013 1. 2 51 Basic Definitions and Principles Study the effects of two or more factors.
