Strengths of correlation
Provides data on both of the strength and direction of a relationship
Strengths of questionnaire
Can quickly obtain vast amounts of data from many participants
Strengths of interview
Provides qualitative data from both answers and their body language
Strengths of observation
Provides a high level of ecological validity due to its a natural setting.
Strengths of case study
Provides lots of data as multiple methods are used

Design issues of case study
Weaknesses of a correlation
Cannot establish cause and effect as we cannot state the cause of behaviour
Weaknesses of a questionnaire
Social Desirability bias where participants want to appear to be better than they are.
Weaknesses of a interview
Interviewer Bias can easily occur as the qualitative data is open to subject interpretations
Weaknesses of observation
Observer bias can easily occur as the observations made are open to subjective interpretations
Weaknesses of a case study
Lacks population validity as only one participant/small group.
