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 672?_ C1 stores a copy of the list L1 into the data-column variable C1.
