**This is a series of three activities for pupils based around making an argument to support a hypothesis.**The pupils choose data from the supplied set and use the appropriate means to present it. The activities do not have a single ‘correct’ answer, and pupils are encouraged to create some form of presentation to support their argument.

The activities are:

- By-pass or High Street? Where should we put a speed camera?
- Bus or train journey? What’s the best way to get to work?
- Cambridge or Kendal? What’s the best town to move to?

Year 10 Objectives covered:

- Independently devise a suitable plan for a substantial statistical project and justify the decisions
- Use an appropriate range of statistical methods to explore and summarise data; including estimating and finding the mean, median, quartiles and interquartile range for large data sets (by calculation or using a cumulative frequency diagram)
- Select, construct and modify, on paper and using ICT, suitable graphical representation to progress an enquiry and identify key features present in the data; including cumulative frequency tables and diagrams, box plots and scatter graphs and lines of best fit (by eye)
- Examine critically the results of a statistical enquiry; justify choice of statistical representations and relate summarised data to the questions being explored
