(Method 2) :
Step 1 : Press [ = ] once to view the first data
DEG ED STAT
2.00
Step 2 : Continue pressing [ = ] once for each data, it will
display 5.00, 5.00, 5.00, 5.00, 9.00, 9.00,
9.00 in sequence.
Adding a data entry
(Ex.3) : Add data 9 = 10 to Ex.1
Step 1 : Press [ DATA ] 10
DEG ED STAT
10.
Step 2 : The calculator updates the statistics as you enter
data. You can then recall all variable statistics to
get the following result : = 6.56, n = 9.00, S =
2.74,
Σ
x = 59.00,
Σ
x
2
= 447.00,
σ
= 2.59,
where data 1 = 2.00, data 2~5 = 5.00, data 6~8
= 9.00, data 9 = 10.00
Editing statistics data
(Ex.4) : Based on Ex.1, correct data 1 = 2 as data 1 = 3
Method 1 :
Press 2 [ 2ndF ] [ DEL ] 3 to overwrite.
Method 2 :
Step 1 : Press [ 2ndF ] [ EDIT ]
DEG ED STAT
0.00
Step 2 : Find out 2 by [ DATA ] or [ = ]
DEG ED STAT
2.00
Step 3 : Enter 3 to overwrite 2
DEG ED STAT
3.
Step 4 : Press [ = ] and [ 2ndF ] [ EDIT ] to exit ED mode,
where those data are changed as data 1 = 3.00,
data 2~5 = 5.00, data 6~8 = 9.00.
(Ex.5) : Based on Ex.1, delete data 1 = 2 .
Method 1 :
Press 2 [ 2ndF ] [ DEL ] to delete 2.
Method 2 :
Step 1 : Press [ 2ndF ] [ EDIT ]
DEG ED STAT
0.00
Step 2 : Find out 2 by [ DATA ] or [ = ]
DEG ED STAT
2.00
Step 3 : Press [ 2ndF ] [ DEL ]
DEG ED STAT

Step 4 : Press [ 2ndF ] [ EDIT ] to exit ED mode, where
those data are changed as data 1~4 = 5.00, data
5~7 = 9.00.
