• The values of the statistical variables depend on the data you in-
put. You can recall them by the key operations shown in the below
table. To predict a value for x (or y) given a value for y (or x), enter
the given value, press [ 2nd ] [ y
^ ] (or [ 2nd ] [ x
^ ] ), and press [ = ]
again. See Example 42~43.
