Data Desk is a fast, easy-to-use data analysis package that has been helping people understand their data since 1986. The program provides interactive tools for analysis and display based on the concepts and philosophy of Exploratory Data Analysis. Data Desk implements many traditional statistics techniques suitable for data from planned experiments and surveys. However, the program's true strength is its powerful tools for data exploration, visualization and mining. All Data Desk's plots and tables are linked together so that points selected in one display highlight in all other displays. Select bars in a bar chart or histogram, slices of a pie chart, rows, columns, or cells of a table, or any points in a scatterplot, rotating plot, dotplot, or boxplot, and the selected points highlight in all plots. Such consistency reveals relationships among several variables, identifies clusters and subgroups and helps you to catch errors and outliers.
