Self report

• A questionnaire is a set of written questions
• One strength of questionnaires is they are quick, able to give a large sample
• One weakness of questionnaires is that they are biased towards people who can read/write fluently
• A structured interview uses predetermined questions
• A strength of structured interviews is that they are standardised, allowing answers to be easily compared
• One weakness of structured interviews is interviewer bias leading to lower reliability
• An unstructured interview is when questions are developed during the interview based on previous answers given
• One strength of unstructured interviews is that they give more detailed answers
• One weakness of unstructured interviews is that skilled interviewers are needed and are less objective
• Self report isn't always reliable because participants may show demand characteristics
• An interviewers body language and tone are examples of researcher effects
• Open questions produce qualitative data
• Qualitative data has more detail but it is harder to compare answers
• Closed questions produce quantitative data
• Quantitative data is easier to compare but shows less detail
• Social desirability is when respondents change their answers to be more socially acceptable
