The Statistics 2-Var App
The Statistics 2-Var App is designed for the study of bivariate statistics. This App provides tools for entering numerical data, calculating 2-
variable summary statistics, and creating 2-variable statistical plots. This App can also provide summary statistics directly to the Inference
App to calculate confidence intervals and test hypotheses. Table 7 summarizes the functionality of the aplet. Press the Apps key, scroll
down to select the Statistics 2-Var App, and press the START menu key to get started. The Statistics 2-Var App starts in the Numeric view.

Summary of Functionality View Name and Display
Press Num to return to this view at any time. This view contains a table with up to ten
columns of data, named C1 through C9 and C0. The menu items are:
• EDIT: opens an input box to edit the chosen value
• INS: inserts a new row in the current column
• SORT: sorts the current column in either ascending or descending order
• BIG: toggles between large and small fonts
• MAKE: generates a column of data based on an algebraic formula
• STATS: provides summary statistics on the currently defined analyses (see Symbolic view)
Statistics 2-Var Numeric View
Press Symb to enter the Statistics 2-Var Symbolic view. You can define up to 5 2-variable
analyses, named S1-S5. Each analysis has the following fields:
• S: defines the independent and dependent columns (and optionally a frequency column)
• TYPE: chooses a function type to fit to your data
• FIT: the equation of your fit
For the independent and dependent columns, you can enter mathematical expressions in
terms of a column name (e.g. 2-C1).
