What are self-report techniques? (2)
Involve asking people about their own experiences or beliefs
Questionnaires and interviews
Self-report techniques: Strengths
Provides insights into how people think and feel
Self-report techniques: Limitations (3)
People may answer in a socially desirable way (social desirability bias)
May not know what they think or feel so might make the answer up
Sample may not be representative leading to sample bias and a lack of generalisability
Questionnaires
Set of written questions
Questionnaires: Strengths (2)
Once designed and tested they can be easily and cheaply distributed to large numbers (lots of data collected)
Respondents may be more willing to give personal information in a questionnaire than an interview
Questionnaire: Weakness
Only filled in by people who can read and write - bias sample, reduces generalisability
Interviews
A real time interaction with another individual, resulting in the collection of data
Structured Interview (2)
Predetermined questions used
No deviation from the list of questions
Unstructured interview
Interviewer free to make changes in the questions
Closed questions
Have a predetermined range of answers from which respondents select one
Open questions
Invites respondents to provide their own answers
Open Questions: Advantages (2)
Respondents can extend on answers
Can generate unexpected answers, allowing researchers to gain new insights into people’s feelings and attitudes
Open questions: Disadvantages (2)
Respondents may avoid giving lengthy answers
Produces qualitative data (non numerical data), harder to analyse and draw conclusion
Closed Questions: Advantages
Produce quantitative data, which is easy to analyse
Closed Questions: Disadvantages (2)
Respondents may be forced to select answers that don’t represent their real thoughts or behaviour - reducing the internal validity
Participants may select ‘don’t know’ and so answers may not be informative
