Answer to Question 1

Applications of experimental design have become increasingly important in manufacturing and other business operations. Experiments to identify variables related to increased production and decreased numbers of defects are important in efforts to improve production operations. The use of dummy variables and multiple regression for experimental design analysis extends the problem types that you can handle without learning additional analysis techniques. This is an important additional advantage for dummy variable procedures.
