How do I calculate correlation coefficients on a TI-89 Titanium calculator?

From Home, press the Mode button, then scroll
down to Exponential Format. Select Scientific.
Press Enter to save your selection. [ If you type in a number less than one and then press
Enter, the number will now be automatically
converted to scientific notation.
Note that the format your calculator uses to display
scientific notation is really not the correct format.
The “E” stands for “x10^”, so using the example to
the right, you would write your answer as follows:
5.8963 x 10-7
If you type in a number greater than 1, the
calculator does not automatically display it in
scientific notation.

How, then, do you get the
calculator to display the number in scientific
notation? Easy. Simply press the green diamond button and
then Enter again and the number will be converted.
Again, when you write the number down, use the
correct format rather than the calculator’s format,
ie. 6.59821 x 108. Also, if this is a final answer, be
sure you express your answer to the correct number
of significant digits.
