Data Entry

To enter statistical data:

Begin by pressing 2nd Data (above #7 key). X01 = should appear on the screen.  The calculator allows for two variables, X and Y, to be entered for the regression function, but only the X variable will be used for this data entry example. 

The yearly return on the Market over a period of five years is given:

            Year                 Market Return
                1                          23.8%
                2                           -7.2
                3                            6.6
                4                          20.5
                5                          30.6
               
Using the up and down arrows, enter the data as follows:
(Press ENTER and down arrow after each entry)

X01 = 23.8
Y01 = 1
X02 = 7.2+/-
Y02 = 1
X03 = 6.6
Y03 = 1
X04 = 20.5
Y04 = 1
X05 = 30.6

Now that the single variable data has been entered, the next step is to perform the statistical calculations.
