- Evaluating data presentation in Minehead
- Questionnaire data
- For the questionnaire data I produced several piece charts as these clearly showed the proportion of responses to each question
- This was for questions such as "Do you approve of the defences- yes/no/don't know"
- A limitation of this technique is that it is hard to read exact percentages for each response
- You also can't tell the number of people who gave which response
- You also can't tell the reasons behind a response
- Cost/benefit data
- To show the cost/benefit data I produced a subdivided bar chart
- This showed all of the costs of different defences and the value of all the benefits it protects
- Eg/ Houses, shops etc
- This made it quick to see the most costly + valuable items and to compare the costs and benefits
- Evaluation
- We can't tell form this where they are located or how much space they take up to see if the defences are in the best location
- To tackle the problems I produced a colour shaded chloropleth map for the value of each building to show their location
- However, its' hard to work out the Toal value from this
- This showed all of the costs of different defences and the value of all the benefits it protects
- To show the cost/benefit data I produced a subdivided bar chart
- Bi-polar assessment
- This is to show the obi-polar assessment of the various defences
- I produced a radar/web graph for the scores on each factor
- Eg/ safety , beauty etc
- The main problem with this is that it is hard to read
- Data processign analysis
- I calculated the costs of each coastal defence (eg/sea wall) and the value of the land protected (eg/ all the shops)
- I calculated the total costs and benefits
- I divided the costs by the benefits to find the cost/benefit ratio
- Questionnaire data
