Content descriptor choose appropriate forms of display or visualisation for a given type of data; justify selections and interpret displays for a given context

Elaborations

• • Elaboration comparing data displays using mean, median and range to describe and interpret numerical data sets in terms of centre and spread using histograms, dot plots, or stem-and-leaf plots
• • Elaboration choosing the type of representations based on the data type: categorical (nominal or ordinal) or numerical (discrete or continuous)
• • Elaboration using different visualisations of data, including non-standard representations such as infographics, and discussing their purpose, intended audience; evaluating how well they communicate responses to statistical questions of interest
• • Elaboration comparing and interpreting stacked bar charts, area charts and line graphs, discussing how they represent larger categories that can be subdivided into smaller categories and how information that can be obtained from these displays can be used for comparison
• • Elaboration using digital tools, including generative artificial intelligence, to generate different data displays and visualisations using existing data sets, and discussing which form is more appropriate for the given context
