Entering Statistical Two–Variable Data

In ALG mode, remember to enter an (x, y) pair in reverse order (y wx) so that y ends up in the Y–register and X in the X–register.

1.Press ¹¡{Σ} to clear existing statistical data.

2.Key in the y–value first and press w.

3.Key in the corresponding x–value and press /.

4.The display shows n, the number of statistical data pairs you have accumulated.

5.Continue entering x, y–pairs. n is updated with each entry.

Example:

Key in the x, y–values on the left, these make the corrections shown on the right:

Initial x, y	Corrected x, y
20, 4	20, 5
400, 6	40, 6
