In this chapter, the description of each
STAT TESTS
instruction shows the unique inferential stat editor for that
instruction with example arguments.
•
Descriptions of instructions that offer the
Data/Stats
input choice show both types of input screens.
•
Descriptions of instructions that do not offer the

The description then shows the unique output screen for
that instruction with the example results.
•
Descriptions of instructions that offer the
