Statistics Using the CFX-9850GB Plus Calculator
Presented by Damian Freiberg and Phil Perkins, CASIO Bursary Students, QUT
Rationale
Both in the current junior and senior mathematics syllabuses statistical methods are a
requirement. The range of knowledge covers histograms, identifying and calculating five number
summaries, box-and-whisker plot, scatterplot, line-of-best-fit, linear regression, correlation
coefficient and coefficient of determination. The new senior syllabus has an expectation that
calculators will be used routinely for calculation in learning these statistical concepts. The graphics
calculator can be used to model real life data or as a tool for simulation to enhance the learning
experiences of students.
