methodology Flashcards
what is self report data?
research methods where pp’s are asked to report information about themselves without researcher interference eg. their own attitudes/beliefs
strength of self report data
- individual answering for themselves so the data is direct and not likely to be affected by subjectivity of research = less bias
weaknesses of self report data x2
- social desirability: pp may answer how they think they should answer which won’t uncover their own meanings
- people may be in different moods on one day compared to another = data may not be true for all situations
describe a survey as a research method
- questionnaires and or interviews to find out what people think of an issue
- 2 types of questions (open and closed)
- 3 types interview: structured, un-structured, and semi-structured
- a survey gathers information by asking questions of a large number of people usually written in questions or face to face interviews
A01 on questionnaires (description)
- questions usually closed + have likert scale questions too.
- for ethical and practical reasons, questions short so pp don’t give up half way through
- pilot study to family and friends to ensure required info will be gathered
- researcher must consider pp design e.g. independent, repeated, matched
what is external reliability
the consistency of a measure or finding over time
what is internal reliability
the consistency of a measure within itself - can be a problem for questionnaires as often many diff Q’s are used to measure the same trait of attitude = use split-half method (Q’s split into half and findings compared from both halves during analysis)
strengths of questionnaires x2
- reliable: bias reduced from researcher as little variation in how pp are asked for information = no interviewer effect
- reliable: well controlled procedures with same set, same order questions so study is replicable to other groups
weakness of questionnaires x2
- no flexibility, if fixed Q’s asked, valuable data may be missed as pp’s can’t expand on their answers
-social desirability: pp’s may respond with what they are expected to say
What are interviews?
involve set questions such as questionnaires, but face to face situation allows the opportunity to expand, or clarify the questions
why may interviews be chosen instead of questionnaires
- ask follow up Q’s
- respondent may be reassurance
- when access is difficult e..g child with mental health problems
structured interview?
follow a set format and may be extra instructions for using the questionnaire such as where and how to expand on asnwers
unstructured interview
not a set format and questions arise from pp’s answers
semi-structured interview
set questions and some of which can be explored further
strengths of interview x2
- questions can be explained and explored further = in depth and detailed data (both qualitative and quantitative data enrichment)
- interviews gain in-depth data likely to be valid, interviewee’s talk in own words and constrained by questions as they are with a questionnaire.
weaknesses of interview x2
- open ended questions = difficult + time consuming to analyse and may be subject to researcher bias
- social desirability
reasons why survey may be a good research method to use
- possible to generalise
- open and closed q’s = more flexibility than lab exp.
- private allows ppl to be honest = higher eco validity
- more ethical than lab
- quantitative put into graphs and charts when summarising data
- repeated for reliability
what is subjectivity
when the analysis of the results includes input from the researcher
what is objectivity
when there is no bias affecting results, including no bias from researcher’s opinions
strengths of closed questions x2
-generate standard replies therefore numbers can be generated and analysed easily = put in graph to compare data spread
- questions are same for all respondents, if meaning is same for all pp’s then the questionnaire is more reliable.
weaknesses of closed questions x2
- fore a choice of answer as pp’s must choose from a set of answers when the pp might not agree with any of the choices: may not include pp’s choice answer. Therefore the respondent may not say what they want to say producing inaccurate and invalid answers.
- difficult to compare as answers could mean different things to pp’s e.g. ‘unsure’ could mean ‘don’t know’ or ‘sometimes yes/no’ but would be scored the same = results invalid
strengths of open questions x2
- pp’s free to answer as they wish = generates more in depth and richer data.
- pp’s can interpret questions as they wish so more valid data as respondents can talk more about what they really think.
weaknesses of open questions x2
- difficult to analyse because the answers are more likely to be detailed and also different from another= selecting themes can be subjective/biased + % can’t be calculated
- pp’s do not always answer in full as open ended questions are more time consuming to complete, they often to fail to answer all questions.
types of data?
quantitative
qualitative
sampling techniques
-random
-stratified
-volunteer
-opportunity
strengths of quantitative data x2
- data can be summarised in graphs and tables, so are easier to analyse and more likely to be drawn from controlled lab sit.
- well controlled procedures and operationalised variables such as well structured questions so can be replicated to test reliability
