Qualitative
Why is having qualitative data collected as well a strength of the study?
Because it can lead to deeper understanding of why people did or did not help
What is one weakness of the study?
The sample of people studied were likely to be people who lived in the city who were used to ignoring people in need. This means it cannot be generalised to the general population.
