StatView is a statistics application originally released for Apple Macintosh computers in 1985.
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).
For example, a user's spreadsheet might contain columns for names of a participant in a survey (a string), sex (a category variable), IQ (integer), and years using a PC (real).
In StatView 4, the user approach changed from touching the to-be-analyzed data in the spreadsheet to clicking on column names in a separate window.
For example, multiway repeated-measures factors could be included in ANOVAs, with the only limit being the memory allocated to the application.
Despite its lack of availability and support and the difficulty of running the application on Mac computers current in 2009, StatView still has some loyal users.
