You have carried out your own fieldwork investigating environmental quality in an urban area.
Name your urban area:
Explain one reason why you chose that urban area.
Using an annotated sketch map, explain how you chose your sites or location for data collection.
Explain why the conclusions that you reached might be unreliable.
In 2017 a group of 20 students carried out questionnaires in an urban area on a Wednesday afternoon. They asked 40 randomly selected residents to select the three problems in the area that they rated as the most serious.
They compared these results with the results of a similar survey gathered by students in 2014 who also randomly selected 40 residents.
These two sets of results are shown below.

The students concluded that the social, economic and environmental conditions in the urban area had improved since 2014.
Assess the evidence for this conclusion.
