ABSTRACT
All of the designs described in chapter 5 can be subjected to randomization tests within Minitab for Windows using the same general procedures. We suggest that you begin by copying all of the files in the Minitab subdirectory on the companion CD-ROM to a convenient directory. There are two kinds of files there: Minitab macros with .txt extensions (des1.txt to des8.txt) and Minitab worksheets with .mtw extensions (des1.mtw to des8unique.mtw). The next step, once this has been done, is to edit the worksheet that corresponds to the design of interest so that it contains your own data, remaining in conformity with the worksheet specifications given in chapter 5. To edit one of the worksheets (e.g., des1.mtw to analyze Design 1 data) open it in Minitab and simply replace the numerical entries in all columns with your own values. Then, if you wish, save the current worksheet in the same directory, calling it owndes1 or something similar (the .mtw extension will be added automatically). To run the macro, with the worksheet open, type in the session window the command %, followed by the full path name to the macro, followed by the name of the macro. For example, if the macro des1 .txt had been stored in a subsubdirectory (called clinical) of a subdirectory (called analyses) of the C: drive, the complete command would be:
%c:\analyses\clincal\des1.txt
If the macro had been on a floppy disk in the A: drive containing no subdirectories, the complete command would be:
%a:\des1.txt
In the remainder of the chapter, the following are listed for each design:
1. The design specifications for the example in chapter 5. 2. The macro for the design, with bolded comments indicating the function of each section
of the macro. 3. The line numbers of the macro in which the number of samples are specified (2000 or
2001, including the actual data) so that the user can easily locate these values to change them (e.g., to 5000 and 5001) if required.
