Acquiring, managing and analysing data

This Content Descriptor from Year 9 Technologies provides the specific knowledge and skills students should learn. Use it to plan lessons, create learning sequences, and design assessments that align with the Australian Curriculum v9.

Content Descriptor

analyse and visualise data interactively using a range of software, including spreadsheets and databases, to draw conclusions and make predictions by identifying trends and outliers

Elaborations

  • • summarising data, its attributes and the relationships between data sets, identifying trends and outliers to draw conclusions and make predictions, for example summarising data about electorates and their demographics, historical swings and exceptions to predict an election outcome
  • • developing interactive visualisations for exploring complex data, for example population, life expectancy and fertility rate in motion charts
  • • using software to visualise and compare data to identify patterns, relationships and trends, for example investigating emerging trends in Australia's industries
  • • exploring machine learning, a form of artificial intelligence where an algorithm is trained using a data set, for example to classify images into categories
  • • adjusting parameters of an AI model to observe the impact of different factors on predicted outcomes; for example, changing the weighting of different input variables to see how much it changes the model's outputs

Year 9 ASTECTDIY910
Year 9 Technologies Achievement Standard
By the end of Year 10 students develop and modify innovative digital solutions, decompose real-world problems, and critically evaluate alternative solutions against stakeholder elicited user stories. Students acquire, interpret and model complex data with databases and represent documents as content, structure and presentation. They design and validate algorithms and implement them, including in an object-oriented programming language. Students explain how digital systems manage, control and secure access to data; and model cyber security threats and explore a vulnerability. They use advanced features of digital tools to create interactive content, and to plan, collaborate on and manage agile projects. Students apply privacy principles to manage digital footprints.
