Once you log on to your personal computer and get into theMinitab environment, you will see the picture shown in Figure B.1 on your PCscreen. The pull-down menus appear at the top of the screen.Menu Commands. Menu commands include:File Edit Data Calc Stat Graph Editor Tools Window HelpBy clicking on any of the above menu commands, we see options included in thatcommand. For example, if we click on the File menu we get the drop-down menuas shown in Figure B.2. The New option allows us to create a new worksheet.Creating a New Worksheet. Creating a new worksheet means to enter new datain the data window. The data window consists of 4000 columns, which are labeledC1, C2, . . . , C4000. The data can be entered in one or more columns dependingon the setup of the problem. In each column, immediately below the labels C1,

USING STATISTICAL SOFTWARE
In the past two decades, use of technology to analyze complicated data has
increased substantially, which not only has made the analysis very simple, but
also has reduced the time required to complete such analysis. To facilitate statistical
analysis many companies have acquired personal computer–based statistical
application software. Several PC-based software packages are available including
BMDP, JMP, Minitab, SAS, SPSS, and SYSTAT just to name a few. A great deal
of effort has been expended in the development of these software packages to
create graphical user interfaces that allow software users to complete statistical
analysis activities without having to know a computer programming or scripting
language. We believe that publishing a book discussing applied statistics without
acknowledging and addressing the importance and usefulness of statistical
software would simply not be in the best interests of our readers. Accordingly,
here we briefly discuss one very popular statistical package, Minitab. It is our
explicit intent not to endorse any specific software package. Each package has its
strengths and weaknesses.
USING MINITAB
Minitab (version 15) provides the options of using commands from the menu
bar, typing in Session commands, or using both. As shown in Figure B.1, in the
Windows environment it has the look and feel of most other Windows applications
where the menu options help you to easily navigate through the package.
Once in the Minitab environment you will see the heading Minitab - Untitled
and three windows:
1. The Data window (Worksheet) is used to enter data in columns denoted
by C1, C2, C3, . . . , C4000.
2. The Session window displays the output and also allows the user to
enter commands when using the command language.
3. The Project Manager window (minimized at startup) displays project
folders, which enable one to navigate through them and manipulate as
necessary.
