The United States Golf Association (USGA) regularly tests golf equipment to ensure that it conforms to the association’s standards. Suppose the USGA wishes to compare the mean distances traveled by four different brands of golf balls struck by a driver (the club used to maximize distance). The following experiment is conducted:

10 balls of each brand are randomly selected. Each ball is struck with a driver by “Iron Byron” (the USGA’s golf robot named for the famous golfer Byron Nelson), and the LO4 distance traveled is recorded. A layout of the experimental design is displayed in Figure 10.2. Identify each of the following elements in this study: response, factors, types of factor, levels, treatments, and experimental units.
