AC9M6ST01

Statistics > (3) Communicate

Australian Curriculum Version 9 Says:

Interpret and compare data sets for ordinal and nominal categorical, discrete and continuous numerical variables using comparative displays or visualisations and digital tools; compare distributions in terms of mode, range and shape.

What this means

This is the first mention of ‘range’. Range is the difference between the greatest and least values. Discrete data typically means the data was collected by means of counting. Continuous data typically means it is determined as a result of measuring.

  • A variety of graph types are mentioned in the elaborations.
    These include:
    • Side-by-side column graphs – comparative data display,
    • Dot plots,
    • Bar charts (graphs) – typically used for discrete data,
    • Line graphs – typically used for continuous data.

Tip

  • Mean and median are first mentioned in Year 7 (AC9M7ST01 and AC9M7ST02)
