This is now version 2.1 of the software. This small update adds a correction for
alpha reliability coefficients - correcting for restriction of range in a set of
observed sample test scores. Click here
to download the zipped program installation. The zipped file is now 4.8Mb! in size and is named
atten2.zip. The application will work on
800x600, 1024x768, and 1400x1024 screen resolutions. The
program contains comprehensive on-line HTML HELP - via a Help button on-screen
in the application. The program can be installed in any convenient subdirectory
by running Setup.exe from within the zip archive (using say Winzip to
open the archive). Alternatively, copy the zip files to a temporary subdirectory
and run Setup.exe from there. It works on Windows 95 and upwards
operating systems. Installed with the program are two 23-page application/help
manuals - one in Ms-Word format, the other a pdf file. These were created from
the HTML help file. This is the first revamp of all the "Barrett" software -
that uses Delphi-6 and HelpMan v.3.2 software, and some 3rd-party components.
