Environmental quality surveys:
* Using a bi-polar scale we scored different characterisitics for the local area from 0-10. 0 being the most negative score and 10 was the most positive
* These included: Building upkeep, green space, paving and roads, litter, noise, number of people
* we went to 3 locations in each of the settlements to ensure that our results were not biased. It made sure that we visited different parts of the settlement to get an overview. This is called stratified sampling
* We wanted to see if the greater population size had reduced the environmental quality.
* We chose 6 factors as this would give us different environmental characteristics to look at
