Abstract
The graphics calculator has found
many uses in secondary school algebra
and calculus, but possibilities in
relation to chance and data have been
less well publicised. This paper provides
an analysis of the potential for using
graphics calculators in the chance
and data components of school curricula.
Differences between scientific and
graphics calculators are highlighted,
most notably concerned with an aspect
of the storage of data. A number of
kinds of graphics calculator use are
described and exemplified: graphical
and numerical data analysis, data
transformations, simulation, statistical
inference and automatic data collection
by calculator. Implications of these
for school curricula and for teaching
practice are suggested.
