The study collected both quantitative and qualitative data using a range of open and closed questions.
A strength of the study is it uses opportunity samples which are quick and convenient and are cost-effective.
A weakness of the study is the sample is not very generalisable as participants were all aged 16 to 18 and the data was only collected in Reigate.
The sample is not very representative of the target population due to only collecting 20 participants so the study is not proportionate.
