10. A scenario

You are a director of a major manufacturing organisation, and collecting various pieces of information for your potential customers, such as on one of your major customers who is based in London, will require delivery lorries to travel the length of the M1. You will investigate the speed on this road using the data available at

You should only use the source specified. You will need to adopt a sampling approach and credit will be given for schemes which show you have considered how to apply the principles of sampling to obtain the best results with the smallest possible dataset.

Report Requirements

Your report should be word-processed.

Credit will be given for the use of an appropriate technical style of presentation.

Your report should address the following topics:

 Your sampling strategy and how it was devised

 Details of the data collected

 Details of your statistical analysis and its results

 Conclusions drawn

 Any relevant background research

Credit will be given for an appropriate use of graphs, tables and charts. All external sources of information must be correctly cited and referenced.

You should include a table of all the data you have collected and any calculations performed in SPSS as an appendix to your report. This is not counted in the page limit. Failure to include this will result in the deduction of marks. Also note that the Traffic England website (link given above) allows you to sign in and save data shots, but any updates on their website may lead to losing of data stored in your account. Thus, it is your responsibility to store this data into your computer(s) and keep it safe for your above task.
