A simple straightforward worksheet, asking students to collect some information and present it as a graph.
Helps students define the differences between Censuses and samples, with examples.
If you choose 16 random feet and put them into a line do you always arrive at the same total length? Using a 16th-century description of a “Rod” length students are asked to take random samples and think about measures and averages.
Here is a set of data with little background. Students are invited, via a series of questions, to turn the data into usable, useful information applying both Mathematical reasoning and use of Statistical methods. It encourages the use of spreadsheets as a means to further enhance the quality of the work and provides scope for further investigation.
Another set of data for students to investigate. The gender of the provider of each data item is given and students are asked to compare males with females. They have to discover all about the data and what information it is giving them.
