Q

weaknesses of self report data x2

A
  • 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

Q

describe a survey as a research method

A
  • 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

Q

A01 on questionnaires (description)

A
  • 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

Q

what is internal reliability

A

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)

Q

strengths of questionnaires x2

A
  • 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

Q

weakness of questionnaires x2

A
  • 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

Q

strengths of interview x2

A
  • 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.

Q

strengths of closed questions x2

A

-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.

Q

weaknesses of closed questions x2

A
  • 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

Q

strengths of open questions x2

A
  • 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.

Q

weaknesses of open questions x2

A
  • 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.

Q

strengths of quantitative data x2

A
  • 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

27
Q

weaknesses of quantitative data x2

A
  • specified response are required so tend not to be valid
  • demand characteristics (may guess aim of the questionnaire
28
Q

strength of mean

A

takes all the values from the raw score into account

29
Q

weakness of mean

A

can be skewed by anomalies

30
Q

strength of median

A

not affected by extreme scores and useful when the scores are ordered data

31
Q

weakness of median

A

does not take account of the values of all the scores and can be misleading if used in small sets of data

32
Q

strength of mode

A

not affected by extreme scores and is useful as shows where the majority of scores lie

33
Q

weakness of mode

A

tells us nothing about the other scores e.g. there may be more than one mode in the set of data

34
Q

what is measures of dispersion

A

how far the data is spread away from the mean, median, mode

35
Q

weakness of range

A

effect by extreme scores and does not tell us distribution around the mean

36
Q

strengths of qualitative data x2

A
  • deals with the ‘why’ rather than ‘what’ e.g. why pp continued shocking to 450V
  • conducted in more natural circumstances and tend to produce more ecologically valid data as they are real life situations
37
Q

weaknesses of qualitative data x2

A
  • difficult to analyse because data can be so different it’s hard to summarise
  • qualitative data is harder to replicate due to lack of control in methods and so lacks replicability
38
Q

analogy for thematic analysis

A

fat cats slowly roll down walls

39
Q

name each stage of thematic analysis

A

familiarisation with data
coding
searching for themes
reviewing themes
defining and naming themes
writing up

40
Q

familiarisation of data?

A

reading data to understand the content

41
Q

coding

A

generating labels that identify features of data

42
Q

searching for themes

A

examine the labels and data to identify patterns of meaning

43
Q

reviewing themes

A

checking potential themes against the data to see if they explain the data and answer the research question

44
Q

defining and naming themes

A

a detailed analysis of each theme and creating an informative name for each one

45
Q

writing up

A

combining together info gained from analysis

46
Q

strengths of thematic analysis x2

A
  • reduces large amounts of data into manageable summary without losing validity
  • encourages researcher to derive themes from the data rather than impose pre-selected themes which is likely to achieve better validity
47
Q

weaknesses of thematic analysis x2

A
  • choosing themes is subjective
  • time consuming
48
Q

strength of random sampling x2

A
  • low bias therefore representative of target pop.
  • can be checked mathematically for bias so more scientific + credible
49
Q

weaknesses of random sampling x2

A
  • cannot be certain sample is representative of all groups = bias
  • hard to ensure everyone in target pop. is available
50
Q

strength of stratified sampling

A

all relevant groups have at least some representation so conclusions can be drawn

51
Q

weakness of stratified sampling

A

difficult to know how many of each group is needed to be representative ie findings may not be generalisable

52
Q

strength of volunteer sampling

A

pp’s more likely to cooperate and are interested so may be less likely to give biased info or go against researchers instructions (demand characteristics)

53
Q

weakness of volunteer sampling x2

A

only certain types of people may volunteer so bias - motivation might make them behave differently
- may take time to get enough volunteers

54
Q

strengths opportunity sampling x2

A
  • allows large number of pp’s to be recruited quickly + not time consuming
  • researcher has more control over who is chosen and so be able to get the sample quickly and efficiently because access is not a problem
55
Q

weaknesses opportunity sampling x2

A
  • those who are picked and willing to take part (self-selecting) = rules out anyone not available/unwilling to take part therefore bias.
  • may not get representatives from all groups and so bias is more likely than other methods e.g. researchers more likely to choose pp of their own age, who look friendlier etc..
56
Q

interviewer effects?

A
  • asked them leading questions
  • or may only focus on aspects of pp’s behaviour which fit their expectations
57
Q

experimenter bias

A

expectations may also influence how they take measurements and analyse their data, resulting in errors that can lead to e.g. accepting false hypothesis.

58
Q

what are extraneous variables? + Examples

A

variables that you can’t control that may affect the results from experiment
e.g. participant variables (age, gender, experience, mood)
situational variables (temp, noise, light)

59
Q

strength of lab experiment

A

care controls = replicable, which means they can be tested for reliability

60
Q

weakness of lab experiment

A

lack ecological and task validity as not measuring ‘real’ behaviour

61
Q

experimenter effects?

A

researcher’s tone of voice, what they’re wearing, gender… etc.. (can affect pp’s answers/actions)

62
Q

strength of field experiments

A

ecological validity + lack of demand characteristics as pp’s don’t know they’re in an experiment

63
Q

weakness of field experiments

A

extraneous variables + harder to control variables and replicate same experiment

64
Q

strength of repeated measures

A

pp’s do all conditions so pp’s variables (features of pp’s that might affect results) are controlled (cancel out)

65
Q

weakness of repeated measures and matched pairs

A

order effects = bias and drawing wrong conclusions e.g. practice effect (may do second condition better from having practice and fatigue effects

66
Q

strength of independent groups

A

no order effects as people do diff conditions

67
Q

weakness of independent groups

A

need more pp’s = takes longer and more costly
