These seven learning activities, which focus on the use of 'real data' using a variety of tools (software) and devices (hardware), illustrate the ways in which content, pedagogy and technology can be successfully and effectively integrated in order to promote learning. In the activities, teachers use the three content strands ...

The 11 learning objects in this collection relate to the use, collection, display, comparison and interpretation of statistical data. Objects in the first category, statistical graphs, enable students to compare and use a broad range of statistical graphs appropriately. Objects in the second category, surveys, explore and ...

Students develop their knowledge of statistical measures, such as mean and median, by examining a dataset about the First Fleet (M007943 'The First Fleet - dataset'). They use the dataset to determine the age of convicts leaving England on the First Fleet, and they construct tables and graphs and complete data investigations. ...

This is a collection of 15 digital curriculum resources that focuses on representing single-variable data, in the context of sampling and quality control in manufacturing, in box plots. Back-to-back (parallel) box and whisker plots are constructed and used to compare datasets. In both contexts, the significance of quartiles ...

• TLF-IDL10087

Explore and observe changes in the least squares and 3-median regression lines, the correlation coefficient, mean and median by dragging data points around a scatter plot graph or entering your own data. Create different regression lines for different sets of data using the copy function and observe how the lines change ...

Check whether a machine is packing most matchboxes with an acceptable number of matches (40–60 matches per box). Look at boxplots made after taking samples of 100 matchboxes. Analyse the data and identify whether results are within the tolerance range. Adjust the machine's scoop size (if needed) to make it work correctly. ...

Check whether a machine is packing most matchboxes with an acceptable number of matches (40–60 matches per box). Take a sample of 100 matchboxes and make a boxplot to analyse the results. Sort the sample data into four equal groups. Identify the range, median, first and third quartile values. Position the data points to ...

Check whether a machine is packing most bags with an acceptable number of rice crisps (20–35 rice crisps per packet). Take a sample of 100 packets and make a boxplot to analyse the results. Sort the sample data into four equal groups. Identify the range, median, first and third quartile values. Position the data points ...

Check whether a machine is packing most matchboxes with an acceptable number of matches (40–60 matches per box). Look at boxplots made after taking samples of 100 matchboxes. Analyse the data and identify whether results are within the tolerance range. Adjust the machine's scoop size or speed (if needed) to make it work ...

Find out what a stem-and-leaf graph is and use it to investigate the truth about different conjectures. Work through a tutorial about stem-and-leaf graphs, and then choose an investigation from a set of three. Enter your own data in some investigations. For example, test the reaction time of your preferred hand against ...
