Ordered-Categorical Data
It may be slightly easier to use environment-nl-numeric.sav because Amos will
assume by default that the numbered categories go in the order 1, 2, 3, 4, with 1 being
the lowest category. That happens to be the correct order. With environment-nl-
string.sav, by contrast, Amos will assume by default that the categories are arranged
alphabetically in the order A, D, SA, SD, with A being the lowest category. That is the
wrong order, so the default ordering of the categories by Amos has to be overridden.
The data file environment-nl-string.sav will be used for this example because then
it will be clear that only the ordinal properties of the data are employed, and also you
can see how to specify the correct ordering of the categories.

EIn the Data Files window, click the File Name button.
