10-6 Statistics aplet
Entering and editing statistical data
The Numeric view ( ) 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 ( ).
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, L1 C1 stores a copy of the list L1 into the
data-column variable C1.
