Educational value
  • This resource is valuable for both teachers and students for the year 9 Australian Curriculum: Mathematics. It is particularly relevant to the content descriptions about data collection, management and comparison. It supports students in identifying everyday questions and issues involving numerical and categorical variables, comparing data displays using measures of location (centre) and spread, and collecting data from secondary sources. The strategies used include back-to-back stem-and-leaf plots and histograms. The terminology used includes 'skewed', 'symmetric', 'bi-modal', 'mean', 'median' and 'range'.
  • The resource may be useful in helping students achieve that element of the year 9 achievement standards that refers to students comparing techniques for collecting data in primary and secondary sources, making sense of mean and median in skewed, symmetric and bi-modal displays and constructing back-to-back stem-and-leaf plots and histograms.
