## Abstract

Inference, or decision making, is seen in curriculum documents as
the final step in a statistical investigation (Australian Education
Council, 1991). For a formal statistical enquiry this may be associated
with sophisticated tests involving probability distributions. For
young students without the mathematical background to perform
such tests, it is still possible to draw informal inferences based on
data of various sorts, for example by comparing two graphical representations
(e.g., Watson & Moritz, 1999). In doing so it is important
to be able to state the assumptions that are the foundation for the
