AC9M7ST02
Official content description
create different types of numerical data displays including stem-and-leaf plots using software where appropriate; describe and compare the distribution of data, commenting on the shape, centre and spread including outliers and determining the range, median, mean and mode

TeachKoala turns this descriptor into a complete lesson — illustrated slides with teacher notes, a differentiated activity sheet and a quiz — aligned to AC9M7ST02 specifically, never an invented code. Your first lesson is free.

What Year 7 Maths students should achieve
Coverage is judged against the achievement standard — not by ticking every content description. These are the official Year 7 Maths standard sentences this code builds towards:
- Students classify polygons according to their features and create an algorithm designed to sort and classify shapes.
- They represent objects two-dimensionally in different ways, describing the usefulness of these representations.
- Students choose between equivalent representations of rational numbers and percentages to assist in calculations.
- Students interpret data in terms of the shape of distribution and summary statistics, identifying possible outliers.
- Students solve problems involving addition and subtraction of integers.
- They solve linear equations with natural number solutions.
The Statistics progression either side of AC9M7ST02
A class can only meet this descriptor if they were taught the one before it. If yours hasn't, that's where the lesson starts — not here.
Taught before · Year 6
- AC9M6ST01interpret 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
- AC9M6ST02identify statistically informed arguments presented in traditional and digital media; discuss and critique methods, data representations and conclusions
- AC9M6ST03plan and conduct statistical investigations by posing and refining questions or identifying a problem and collecting relevant data; analyse and interpret the data and communicate findings within the context of the investigation
Builds towards · Year 8
- AC9M8ST01investigate techniques for data collection including census, sampling, experiment and observation, and explain the practicalities and implications of obtaining data through these techniques
- AC9M8ST02analyse and report on the distribution of data from primary and secondary sources using random and non-random sampling techniques to select and study samples
- AC9M8ST03compare variations in distributions and proportions obtained from random samples of the same size drawn from a population and recognise the effect of sample size on this variation
Other Year 7 Statistics codes
- AC9M7ST01acquire data sets for discrete and continuous numerical variables and calculate the range, median, mean and mode; make and justify decisions about which measures of central tendency provide useful insights into the nature of the distribution of data
- AC9M7ST03plan and conduct statistical investigations involving data for discrete and continuous numerical variables; analyse and interpret distributions of data and report findings in terms of shape and summary statistics
