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.
This learning program is made up of the following 3 topics, broken down into 30 concepts.
Describe how a random sample may be selected in order to collect data
Construct appropriate survey questions
Investigate techniques for collecting data including census, sampling or observation
Identify the difference between data collected from primary and secondary sources
Interpret information collected from a survey
Discuss constraints that may limit the collection of data or result in unreliable data
Collect and record information from a survey
Discuss bias in the selection of a sample
Recognise variables as categorical or numerical (discrete or continuous)
Investigate the effect of outliers on the mean, median, mode and range using small data sets
Calculate the mean of ungrouped data sets
Identify the mode of ungrouped data sets
Calculate the median of ungrouped data sets
Calculate the range of ungrouped data sets
Interpret a column graph
Recognise and justify which measure of central tendency is appropriate for the data type
Construct a column graph
Construct divided bar graphs
Construct line graphs
