There are seven sub-modes within STAT mode, corresponding
to each of the functions below:
Key operation

m 1 1
m 1 2
m 1 3
m 1 4
m 1 5
m 1 6
Entering statistical data
Before you can perform statistical calculations, you will need to
enter your data. In STAT mode, use > and J (the Q
key) to enter the following:
For a single-variable data set:
Value J
Value > frequency J (To enter multiples of the same
value)
For a two-variable data set:
x value > y value J
x value > y value > frequency J (To enter multiples
of the same x and y values)
Note: Before entering data, clear any previously entered data
from memory by doing either of the following:
• Press . b in STAT mode.
• Switch sub-modes within STAT mode.
