Data Desk is a software program for visual data analysis, visual data exploration, and statistics. It carries out Exploratory Data Analysis (EDA) and standard statistical analyses by means of dynamically linked graphic data displays that update any change simultaneously.
Data Desk was developed in 1985 by Paul F. Velleman, a statistics professor at Cornell University who had studied exploratory data analysis with John Tukey. Data Desk was released in 1986 for the Macintosh. It provided most standard statistical methods accessed through its own desktop interface.
In 1997, Data Desk was released for Windows, and included a General Linear Model (GLM), multivariate statistics, and nonlinear curve fitting. DD/XL is an add-in for Microsoft Excel that adds Data Desk Functionality directly to the Spreadsheet
Data Desk's developer, Data Description, pioneered linked graphic displays including a 3-D rotating plot and graphical slider control of parameters. It has also developed proprietary technology for computer-based multimedia instruction and currently provides contract data analysis services.
