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.
