research methods Flashcards
what is an interview?
asking questions in real time and analysing answers after
- information gained directly from participants
define ‘researcher effect’
the influence of the interviewer directly on the respondent
- eg being rude
define ‘researcher bias’
interpretation of response by the interviewer
define ‘response bias’
the tendency of a participant to respond in a particular way
describe the characteristics of an interview
- mostly open questions, generating qualitative data
- smaller data sets lower generalisability
- relevant questions are used and recorded/transcribed which increases reliability
describe a structured interview
- standardised questions asked in same order
- often used in job candidate screening
what are strengths of a structured interview?
- high response rate
- quick
- comparable
- high reliability
what are weaknesses of a structured interview?
- less detail
- can lack validity
what is a semi structured interview?
guide of topics but phrasing and timing is up to the interviewer
used in clinical interviews
what is a strength of a semi structured interview?
- detailed
- flexible
- generates rich, easy to analyse data
what are weaknesses of semi structured interviews?
- could have irrelevant data
- lack reliability
what is an unstructured interview?
everyday conversation without pre determined questions
what are strengths of unstructured interviews?
- deeper discussion
- questions can be adapted and improvised to improve relevancy
what are weaknesses of unstructured interviews?
- low reliability
- time consuming
- less objective
what is a questionnaire?
a self report technique which investigates beliefs and opinions through pre determined questions where respondents record their own answers
what is an open question?
no fixed response
generates qualitative data
what is a closed question?
fixed response
generates quantitative data
what is a strength and weakness of qual data?
- more detailed evaluation
- hard to find averages
what is a strength and weakness of quant data?
- easy to analyse
- extraneous variables not considered
what is a ranked scale?
- respondents assess views on 1-5 scale
- objective
- quantitative data
- easy to draw conclusions
what is a likert scale?
- respondent rates how much they agree
- quantitative data
- allows for degrees of opinion or no opinion
what are characteristics of a good questionnaire?
- no leading / confusing questions
- open and closed questions
- avoid lists that are long or asking 2 diff things in one question = reduces fatigue
- start with interesting questions
- check / test to see if it works
what are strengths of questionnaires?
- large sample
- flexible, quick and efficient
- cost effective
- anonymous = more valid response and reduces social desirability
- standardised procedures = reliable
what are weaknesses of questionnaires
- risk of social desirability to appear favourable
- poor response rate = unrepresentative
- leading qs / researcher bias could flaw results
- written at 11 year old level = age limited
