About the Statistics aplet
The Statistics aplet can store up to ten data sets at one 
time. It can perform 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 
 function accessible from the Statistics aplet’s 
Numeric view screen.
