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 12 learning objects in this collection relate to the use, collection, display, comparison and interpretation of data. Objects in the first category, statistical data graphs, enable students to explore data using a range of graphical analysis tools. Objects in the second category, analysing surveys, enable students to ...

• TLF-IDR11593

Students develop their knowledge of summary statistics, such as the mode and median of data sets, by examining a dataset about the First Fleet (M007943 'The First Fleet - dataset'). They use data about the cost of crime to construct tables and graphs, and to complete data investigations. Students complete these activities ...

• TLF-IDR12185

This professional article describes how to develop informal inference through a series of four mathematical activities about body measurements. Students develop an understanding of the significance of accuracy in measurement, the suitability of different measures of centre, the effects of outliers and arriving at sensible ...

• 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 ...

• TLF-IDL2342

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 ...

• TLF-IDL5912

Find out what a stem-and-leaf graph is. Find out what a back-to-back stem-and-leaf graph is. Work through this tutorial to understand the features of stem-and-leaf graphs, and how they are used to display and to compare two data sets. Observe how the mean and median of the data sets can be used to interpret information. ...

• TLF-IDL5915

Are reaction times using a person’s preferred hand faster than using the non-preferred hand? Display the given data, including your own time, in a back-to-back stem-and-leaf graph to investigate the answer to this question. Identify the median for preferred and non-preferred hands and use the two means to draw a conclusion ...

• TLF-IDL5911

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 ...
