To Enter data for statistical analysis

Before entering data, press [ 2nd ] [ SET UP ] [
to set Frequency column as On or Off. FREQ column enables you to
enter the number of repeats for each of the same value occurred.
See Example 49.
1. From the STAT menu, choose a calculation type. There will be
two Data Editor formats (1–VAR or 2–VAR / regression Data)
depending on the type you select.
2. Enter an x - value and press [ = ].
3. Enter the frequency ( FREQ ) of the x-value (in 1–VAR mode) or
the corresponding y-value ( in 2–VAR mode ) and press [ = ].
4. To enter more data, repeat from step 3.
5. To exit Data Editor mode to Result displaying mode, press [ AC ]
and then [ 2nd ] [ STATVAR ] to display STATVAR menu. ( See
table below )

To analyze data you have entered

Once you have entered your data, you can use the functions in
STATVAR menu by pressing [ 2nd ] [ STATVAR ]:
