Entering Statistical Two–Variable data
In ALG mode, remember to enter an (x, y) pair in reverse order (y
w
x) 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.
