Example 5: To use the paired-variable data input in Example 4 (page 70)
and display the results of the two regression calculations shown below
• The regression equation "y = a + bx" coefficients (a, b), and the
correlation coefficient (r) when linear regression is performed on the
data
• The regression equation "y = a + bx + cx
2
" coefficients (a, b, c) when
quadratic regression is performed on the data
Note
• For information about regression calculation types supported by the Statistics app, see
the "Supported Regression Type List" (page 73).
1. Perform steps 1 through 5 of the procedure under Example 4 (page
70).
2. Select [Reg Results], and then press
.
• This displays the regression type menu.
3. Select [y=a+bx], and then press .
• This displays the linear regression Reg Results screen.
4. Press or to return to the Statistics Editor.
5. Press , and then select [Reg Results] > [y=a+bx+cx
2
].
• This displays quadratic regression Reg Results screen.
6. Press or to return to the Statistics Editor.
•
For the meanings of the variables shown on the Reg Results
screen, see the "List of Statistical Value Variables and Statistical
Calculation Functions" (page 76).
