Tasks 1. Take a look at the Ingram valley data sheets. In particular look at the bed load data and cross section data 2. Think of 2 hypotheses that you could test about both the bed load data and velocity data. For example - "There is a significant relationship between the cross section of the river and the pattern of velocity within that channel." 3. Produce a graphical or statistical resources that helps you to analyse your hypothesis. If you need help use the help guide videos below. 4. Fully analyse your resource - what does it show? Why does it show this and how does it link to the geography you have studied? Are there any anomalous (unusual) results and why? 5. Respond to your hypothesis |
