Assembly Language Programming: Inferential Statistics and Distribution Functions

Test and Interval Output Variables

The inferential statistics and distribution variables are calculated as indicated
below. To access these variables for use in expressions, press - w and
then select the menu listed in the
below.
All inferential statistics variables begin with the letters
other variables.
If you upload TI-86 variables that contain the sigma (s) or mu (m) symbols to your
computer, the Graph Link program will prompt you to rename them. This is
because computer file names cannot contain these symbols. When you download
the renamed variables to your TI-86, Graph Link restores the symbols and the files
are loaded in the calculator under their original names.
Important: If you do not rename the sigma variables (sts.86n, sts1.86n, and
sts2.86n), they are stored on the computer under the names st_.86n, st_1.86n, and
st_2.86n. You cannot delete or rename these files on your computer, and you will
not be able to download them to your calculator.
