Overview

Year 8 Data is part of Statistics and Probability in the Australian curriculum. We show students how to collect data, identify constraints when collecting data, and critically analyse bias in surveys and other forms of data gathering. Students learn about numerical and categorical data, calculate measures of centre (mean, median & mode) and range, and learn how to read and create different types of graphs and tables.

Topics & Concepts We Cover

This learning program is made up of the following 3 topics, broken down into 30 concepts.

  • Data Collection 9 concepts

    1. Collect and record information from a survey

    2. Identify the difference between data collected from primary and secondary sources

    3. Describe how a random sample may be selected in order to collect data

    4. Discuss constraints that may limit the collection of data or result in unreliable data

    5. Interpret information collected from a survey

    6. Construct appropriate survey questions

    7. Discuss bias in the selection of a sample

    8. Investigate techniques for collecting data including census, sampling or observation

    9. Recognise variables as categorical or numerical (discrete or continuous)

  • Calculating Statistics 5 concepts

    1. Investigate the effect of outliers on the mean, median, mode and range using small data sets

    2. Identify the mode of ungrouped data sets

    3. Calculate the median of ungrouped data sets

    4. Calculate the mean of ungrouped data sets

    5. Calculate the range of ungrouped data sets

  • Data Representation 16 concepts

    1. Interpret a column graph

    2. Construct a column graph

    3. Recognise and justify which measure of central tendency is appropriate for the data type

    4. Interpret divided bar graphs

    5. Interpret line graphs

    6. Construct divided bar graphs

    7. Interpret sector graphs

    8. Construct line graphs

    9. Construct sector graphs

    10. Interpret dot plots

    11. Construct dot plots

    12. Interpret stem-and-leaf plots

    13. Construct stem-and-leaf plots

    14. Use a tally to organise data into a frequency distribution table

    15. Construct a frequency histogram and polygon for ungrouped data

    16. Identify and explain which graph types are suitable for the type of data being considered
