StatView
StatView is a statistics application originally released for Apple Macintosh computers in 1985.
StatView was one of the first statistics applications to have a graphical user interface, capitalizing on the Macintosh's. A user saw a spreadsheet of his or her data, comprising columns that could be integers, long integers, real numbers, strings, or categories, and rows that were usually cases (such as individual people for psychology data). Columns had informative headings; rows were numbered. Category data looked like strings (e.g., a column headed "sex" would have entries of "male" and "female", but these were coded by the application as integers). Category data were used to perform inferential statistical tests such as t tests, ANOVAs, and chi square tests. To calculate statistics, a user clicked on particular column headings, designating them as an x value and one or more y values. Then the user used the application's menus to choose descriptive statistics or inferential statistics.
