Question 4

What are the 5 strengths of case studies?

Lesson 17

Answer 4

1. As researchers are focusing on one individual / small group they can collect rich, in depth data&raquo_space; makes findings more valid
2. Ppts are usually studied as part of their everday life which means that the study has high ecological validity
3. Allow researchers to investigate topics that are impractical / unethical to investigate experimentally
4. Unique cases can challenge existing ideas / theories –> suggest new areas and hypothesis for future research
5. Complex interactions can be studied rather than simple cause + effect relationships being found

Question 5

What are the 2 weaknesses of case studies?

Lesson 17

Answer 5

1. As researchers are focusing on one individual the case may be unique –> makes generalisations very difficult
2. As ppts are studied in depth an attachment can form which reduces the objectivity of data collection + analysis –> reduces validity of findings
