Deleting data
The method to delete data depends on whether you have already
stored the data by next pressing [ DATA ] key or not.
To delete data you just input but have not yet stored it by next pressing
[ DATA ] , simple press [ CE ].
To delete data that you have already stored by next pressing
[ DATA ] ,
(A) To delete single–variable data using the following syntaxes :
# < x value > [ 2nd ] [ DEL ]
# < x value > [ x ] < Number of repeats > [ 2nd ] [ DEL ]
(B) To delete paired–variable / regression data using the following
syntaxes:
# Individual data-set : < x value > [
] < y value > [ 2nd ] [ DEL ]
# Multiple data-set with the same value :
< x value > [
] < y value > [ x ] < Number of repeats > [ 2nd ]
[ DEL ]
If you enter and delete a value that isn't included in the stored data by
mistake, " dEL Error " appears, but the previous data are still retained.
Editing data
Press [ 2nd ] [ EDIT ] to enter EDIT mode. The EDIT mode is
convenient and friendly for you to view, correct, delete data.
(A) In 1–VAR mode, the method to view data depends on whether you
want to view data item or not.
# Each time you press [ DATA ], first data item appears 1 second
and then the corresponding value.
