Program 1: Comparative Experiments - Demonstrating Change or Equivalence
March 19, 2010

A common situation in industry is to conduct experiments to demonstrate that a change, perhaps an improvement, has occurred, or that no change has occurred, thereby establishing equivalence. Thus, comparative experiments are conducted to show that the new process has less variability than the old, that the new formulation is better than the old, or to show that two product designs or two measurement methods are equivalent. Such problems are often analyzed using a t-test, an F-test or an ANOVA. Such hypothesis tests, when blindly applied, can lead to disastrous results. For one company, this SOP caused an unnecessary delay of three months and an unnecessary expenditure of over $250,000!

The purpose of this seminar is to provide practical guidance to conduct comparative experiments, and answer questions such as:
• What is wrong with the t-test and the F-test as usually practiced?
• What to replace these tests with?
• How to make multiple comparisons?
• How much data to collect?
• How to reduce sample sizes?
• How to use software to design and analyze comparative experiments?
