strip graphs

In this unit students make statements about data displays. Students evaluate statements as true or false using the features of the data to support their evaluation.

In this unit students will identify how to plan and carry out a statistical investigation; this will be modelled using a context of voting.  Once students are familiar with the four keys steps of carrying out a statistical investigation of;

• Write questions for statistical investigations and design a method of collection of data.
• Display collected data in an appropriate format.
• Make statements about implications or possible actions based on the results of an investigation.
• Make conclusions on the basis of statistical investigations

they will repeat the process to undertake their own statistical investigation in pairs or small groups.

In this unit we begin by investigating the amount of water contained in a carrot. We plot the "weight" of the carrot using a line-graph as the water in the carrot evaporates. The students also pose their own carrot questions for investigation.

This week we collect data using our fridge as the context. We present the data as dot plots, strip graphs and pie charts.

This week we collect data about sporting activities and present the data using stem-and-leaf graphs and bar charts.
