Year level: 5

Strand: Statistics

Lesson length: 75 mins

In this lesson, students acquire data related to the altitudes reached by fledgling osprey practising flight. Students represent and interpret the data, discussing and reporting on the data distribution including the range and mode.

This lesson is the first in a series of six lessons that connect the cross-curriculum priority of Sustainability, Statistics and the Science learning area: Science as a human endeavour. AC9S5H01, AC9S6H01 and AC9S5H02, AC9S6H02.

This lesson was developed in collaboration with Conservation Without Borders. Data and information provided by Tweed Valley Osprey Project.

### Achievement standard

By the end of Year 5, students interpret and compare datasets for ordinal and nominal categorical, discrete and continuous numerical variables using comparative displays or visualisations and digital tools. They identify the mode and interpret the shape of distributions of data in context. They compare distributions of discrete and continuous numerical and ordinal categorical datasets as part of their statistical investigations, using digital tools.

### Content descriptions

Students acquire, validate and represent data for nominal and ordinal categorical and discrete numerical variables, to address a question of interest or purpose using software including spreadsheets; discuss and report on data distributions in terms of highest frequency (mode) and shape, in the context of the data.

### General capabilities

Numeracy

• Interpreting and representing data (Level 4)

### Cross-curriculum priorities

Sustainability

• Futures (SF1)

Keep a copy of each student’s approach to identifying the mode. Make note of the strategy used and their proficiency in correctly identifying the mode. Create a class checklist to record students’ proficiency in identifying the range and mode in a dataset. Use this to guide the need for follow-up small group teaching.

If students have created a chart using a spreadsheet, save a digital version to view progress in the use of spreadsheet software, such as Excel (MS) or Numbers (iOS). Also note if it includes a suitable title, labels for the axes and if it displays the information correctly.

Some students may:

• have limited familiarity with working with data using a spreadsheet
• require support to interpret different charts and to choose the most suitable chart to represent a dataset
• require guidance to identify the mode and data range.

Prior to this lesson, it is assumed that students have knowledge of:

• interpreting information in a table
• representing data in column graphs
• different ways to visualise data other than a column graph.

It is also assumed students are familiar with terms such as:

• range
• mode
• position and location
• height and altitude
• migration.

Altitude is the height of an object in relation to the ground level.
