  • Chance

    • ACMSP225 List all outcomes for two-step chance experiments, both with and without replacement using tree diagrams or arrays. Assign probabilities to outcomes and determine probabilities for events

    • ACMSP226 Calculate relative frequencies from given or collected data to estimate probabilities of events involving 'and' or 'or'

      • ACMSP226.a using Venn diagrams or two-way tables to calculate relative frequencies of events involving 'and', 'or' questions

      • ACMSP226.b using relative frequencies to find an estimate of probabilities of 'and', 'or' events

    • ACMSP227 Investigate reports of surveys in digital media and elsewhere for information on how data were obtained to estimate population means and medians

      • ACMSP227.a investigating a range of data and its sources, for example the age of residents in Australia, Cambodia and Tonga; the number of subjects studied at school in a year by 14-year-old students in Australia, Japan and Timor-Leste

  • Data representation and interpretation

    • ACMSP228 Identify everyday questions and issues involving at least one numerical and at least one categorical variable, and collect data directly and from secondary sources

      • ACMSP228.a comparing the annual rainfall in various parts of Australia, Pakistan, New Guinea and Malaysia

    • ACMSP282 Construct back-to-back stem-and-leaf plots and histograms and describe data, using terms including 'skewed', 'symmetric' and 'bi modal'

    • ACMSP283 Compare data displays using mean, median and range to describe and interpret numerical data sets in terms of location (centre) and spread
