Question 11

Cause study cons

Answer 11

• by only studying one individual/small group it is very difficult to generalize any findings to the wider population since results are likely to be so unique, lacks external validity
• researcher’s own subjectivity may pose a problem as they may be bias or just see what they want to see, so this can interfere with the validity of the findings/conclusions
