About the Statistics apiet
The Statistics apiet 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 apiet 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 apiet are saved in
variables, and many of these variables are listed by the
function accessible from the Statistics apiet’s Numeric view
screen.
