Entering and editing statistical data
The Numeric view (
>180@) is used to enter data into the
Statistics aplet. Each column represents a variable named C0
to C9. After entering the data, you must define the data set in
the Symbolic view (
>6<0%@).
H I N T A data column must have at least four data points to provide
valid two-variable statistics, or two data points for one-
variable statistics.
You can also store statistical data values by copying lists from
HOME into Statistics data columns. For example, in HOME,
L1 TUPc• C1 stores a copy of the list L1 into the data-column
variable C1 .
