PHStat2 readme file.
PHStat2 is Windows software that assists you in learning the concepts of statistics while using Microsoft Excel. PHStat2 allows you to perform many common types of statistical analyses working with and using the familiar Microsoft Excel interface. PHStat2 is an enhanced version of the original PHStat statistical add-in system. If you have used PHStat previously, read the “Whats New?” section to discover the improvements that PHStat2 contains. (In your textbook, you should interpret any general reference to “PHStat” as a reference to PHStat2.)
The rest of this document is organized into sections to assist you in setting up and using PHStat2. The “Whats New in PHStat2” section of this file can also be found in the PHStat2 help system (select Help for PHStat2 from the PHStat menu in Microsoft Excel and look in the “Welcome to PHStat2” topic).

1 Technical requirements for PHStat2
There are separate requirements for using PHStat2 and running the PHStat2 setup program. The requirements for running the setup program are more exclusive. If you plan to setup PHStat2, make sure to review all of the requirements that follow.
Requirements for using PHStat2:
Windows 98/98SE/ME/NT 4.0/2000/XP Home/XP Pro computer system.
Microsoft Excel 97/2000/2002(Office XP)/2003 or later. Excel 97 users must apply the SR-2 or a later free update from Microsoft. PHStat2 is not compatible with Microsoft Excel 95 or the Macintosh versions of Microsoft Office and Excel.
Screen resolution settings set to 800 by 600 pixels or 1024 by 748 pixels, recommended. PHStat2 will run with any screen resolution settings, but setting your system to use Large Fonts or setting your resolution to the minimum 640 by 400 pixels may truncate or obscure PHStat2 message boxes and parts the Microsoft Excel application window.
Microsoft Excel Data Analysis ToolPak and Analysis ToolPak-VBA installed (supplied on the Microsoft Office/Excel program CD).
Microsoft Office macro security level set to Medium (see topic 3 “Configuring Microsoft Excel Security for PHStat2” below, does not apply to Microsoft Excel 97 users).
Updated anti-virus program, optional but recommended.
Internet access (for downloading updates to Microsoft Excel, from www.microsoft.com, and PHStat2, from www.prenhall.com/phstat, as they become available), optional but recommended.
Requirements for running the PHStat2 setup program:
CD-ROM or DVD-ROM drive.
Approximately 10 MB hard disk free space while running the setup program and 3 MB hard disk space after program setup. On some older systems, the Windows system files that may get replaced or added during the setup process will require up to 6 MB additional hard disk space.
Windows user account with administrator or software-installing privileges (applies only to Windows NT/2000/XP or networked users only). Student or faculty accounts used to login onto networked computers in academic settings typically do not have this privilege. If you have such an account, ask your network or lab technician for assistance.
2 Configuring Microsoft Excel Components for PHStat2
Several components of Microsoft Excel need to be already installed before you can set up PHStat2. Depending on the options chosen when Microsoft Excel was originally set up on your system, these components may not have been set up previously on your system. To double-check that your copy of Microsoft Excel contains these necessary components, open Microsoft Excel and:
Select Tools | Add-Ins.
In the Add-Ins dialog box that appears, select the Analysis ToolPak and Analysis ToolPak – VBA check boxes from the Add-Ins available list and click the OK button.
Exit Microsoft Excel (to save the selections).
If one or both of the Analysis ToolPak choices do not appear in the Add-Ins available list, you will need to rerun the Microsoft Excel (or Office) setup program using your original Microsoft Office/Excel CD-ROM or DVD.
3 Configuring Microsoft Excel Security for PHStat2
(This section does not apply to Microsoft Excel 97 users. Older copies of Microsoft Excel 2000 that have never been updated also do not contain the macro security setting described below. If you are using such an older copy, consider updating it using the downloads available from the Microsoft Office web site before continuing. )
The Microsoft Office macro security level must be set to Medium in order to allow PHStat2 to properly function. To double-check that the security level is not set to High, which would prevent PHStat2 from functioning properly, open Microsoft Excel and:
Select Tools | Macro | Security.
In the Security Level tab of the Security dialog box that appears, select the Medium option button and click the OK button.
If you select the High option button in the Security dialog box, you will prevent PHStat2 from properly functioning. (Selecting the Low option button is considered a poor practice and not recommended, even as PHStat2 will function properly at this setting.) Your selection in the Security dialog box affects all programs in the Microsoft Office suite. When you are finished using PHStat2, you can set the security to High, if you so choose, so long as you remember to reset this level to Medium before attempting to open and use PHStat2.
If you cannot see the Macro choice on the Tools menu, it may be hidden from view due to the way that Microsoft Office is currently displaying menu choices. To double-check this, open Microsoft Excel and:
Select Tools | Customize.
In the Customize dialog box, clear (uncheck) the Menus show recently used commands first check box if it is checked and
