Welcome to STATGRAPHICS Online, a web site designed for interactive statistical analysis over the Internet. STATGRAPHICS Online implements a selected set of STATGRAPHICS procedures, using ASP.NET web services to perform the calculations on a web server. You may enter data by hand, read data from various types of files (including Excel), copy and paste data from other applications, or analyze the StatPoint sample data sets.

If you wish to analyze your own data, you must purchase a monthly subscription. Site licenses are also available for organizations that wish to install STATGRAPHICS Online on a local server. Demo datasets are also provided which may be analyzed without purchasing a subscription.

WE RECOMMEND THE USE OF THE INTERNET EXPLORER OR FIREFOX BROWSER.
These browsers support client-side scripting, which facilitates data entry in the data grid.
The site will also run using downlevel browsers such as Safari or Opera, but data entry will require more frequent page loads.
