StatView was one of the first statistics applications to have a graphical user interface
Graphical user interface
In computing, a graphical user interface is a type of user interface that allows users to interact with electronic devices with images rather than text commands. GUIs can be used in computers, hand-held devices such as MP3 players, portable media players or gaming devices, household appliances and...

 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 menu

In a restaurant, a menu is a presentation of food and beverage offerings. A menu may be a la carte – which guests use to choose from a list of options – or table d'hôte, in which case a pre-established sequence of courses is served....

Descriptive statistics quantitatively describe the main features of a collection of data. Descriptive statistics are distinguished from inferential statistics , in that descriptive statistics aim to summarize a data set, rather than use the data to learn about the population that the data are...

Polls about public opinion, such as political beliefs, are reported in the news media in democracies....

A window is a transparent or translucent opening in a wall or door that allows the passage of light and, if not closed or sealed, air and sound. Windows are usually glazed or covered in some other transparent or translucent material like float glass. Windows are held in place by frames, which...

StatView 2 was called StatView SE + Graphics. It included ANOVA with one repeated-measure and, remarkably, a factor analysis
Factor analysis
Factor analysis is a statistical method used to describe variability among observed, correlated variables in terms of a potentially lower number of unobserved, uncorrelated variables called factors. In other words, it is possible, for example, that variations in three or four observed variables...

. 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. This lack of immediacy was compensated for by an increase in the number of statistical tests that could be performed and in the power of existing tests. For example, multiway repeated-measures factors could be included in ANOVAs, with the only limit being the memory allocated to the application. There were ANCOVA
ANCOVA

Despite its lack of availability and support and the difficulty of running the application on computers current in 2009, StatView still has some loyal users
