About the Statistics aplet

The Statistics aplet can store up to ten separate data sets at one time. It can do one-variable or two-variable statistical analysis of one or more sets of data.

The Statistics aplet 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 values in HOME and recall the values of specific statistics variables.

The values computed in the Statistics aplet are saved in variables, and many of these variables are listed by the 67$76_ function accessible from the Statistics aplet’s Numeric view screen.
