Statistics data can be entered and
evaluated using the statistics buttons on the top row. You can
select the statistics button group by using the main menu (options tab),
or by scrolling through the top-row button sets using the "up" button on
your device.
Enter statistics pairs of data by using the "Sigma+" key. You first key in
the Y value, then the X value, then tap the 'Sigma+' button, thus:
- Y value
- Enter (or '=' button in algebraic mode)
- X value
- Sigma+
This will load the statistics pairs into a statistics 'project' database. Each
entry is added to the end of the list. Once the data has been entered, you can
tap the "stat" button to review/edit the list, or to see the statistics
calculations.
Tapping on any of the other statistics functions will simply open the 'Statistics'
screen at the appropriate tab.
