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%@).

HINT

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,

672?_

C1 stores a copy of the list L1 into the data-column

variable C1.
