3 level 3 factor factorial design example Three level full factorial designs Three level designs are useful for investigating quadratic effects The three level design is written as a 3 k factorial design It means that k factors are considered each at 3 levels These are usually
How to generate reasonable 3 k p fractional factorial designs and understand the alias structure The fact that Latin square and Graeco Latin square designs are special cases of 3 k fractional factorial design Mixed level This section will look at how to add three level factors starting with two level designs obtaining what is called a mixed level design We will also look at how to add a four level factor to a two level design

Example design and analysis of a three factor experiment This example should be done by yourself It is based on Question 19 in the exercises for Chapter 5 in Box Hunter and Hunter 2nd edition The data are from a plastics molding factory that must treat its waste before discharge If one of the independent variables had a third level e g using a handheld cell phone using a hands free cell phone and not using a cell phone then it would be a 3 2 factorial design and there would be six distinct conditions
The video demonstrates the concise method of computation of contrast effect for three level factorial design illustrated through 3 2 design A marketing manager wants to study the influence that three categorical factors have on the ability of test subjects to recall an online advertisement Because the experiment includes factors that have 3 levels the manager uses a general full factorial design
