24 6 (a) Study Figure 6 in the Resource Booklet. A group of students collected data about footpath erosion at Studland Bay, a sand dune coastline in Southern England. They measured vegetation cover across a transect on: 1. a managed footpath 2. an unmanaged footpath. They presented their findings as two kite diagrams. (i) Identify two impacts of footpath management.

Turn over 25 (iv) The students also collected data at ten sites along the unmanaged footpath, measuring width at 30-metre intervals away from the car park, northwards. They used this data to test the relationship between the width of the footpath and distance from the car park. Explain how the use of a statistical method would help their investigation about footpath erosion.
