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.
