Closed questions offer a small number of explicitly stated alternative responses and no opportunity for participants to expand of the answers. produce quantitative data.
STRENGTHS: easy for participants to respond to, so large amounts of data can be collected quickly making data more reliable and easier to assess a large sample which can make the research more generalisable. the quantitative data produced is easy to compare and analyse. (modes, medians can be found and put on graphs etc)
WEAKNESSES: only quantative data can lack detail thus lowering validity. Risk of response biases (such as constatly saying 'yes').
Open questions allow participants to give full and detailed answers in their own words, no categories or choices are given. Produces qualitative data.
STRENGTHS: Qualitative data provides detail so participants can fully express their answers, raising validity.
WEAKNESSES: Qualitative data can be time consuming to analyse as themes need to be identified and extracted. Interpretation of the data can be subjective, potentially reducing inter-rater reliability. Findings may be less generalisable.
