Statistics 2Var app

The Statistics 2Var app can store up to ten data sets at one time. It can perform two-variable statistical analysis of one or more sets of data.

The Statistics 2Var app starts with the Numeric view which is used to enter data. The Symbolic view is used to specify which columns contain data and which column contains frequencies.

You can also compute statistics in Home and in the

Spreadsheet app.

The values computed in the Statistics 2Var app are saved in variables. These can be referenced in Home view and in other apps.
