Challenges: Data quality
(Online data collection)

A

Missing values : Researcher must decide whether to keep participants data or leave it depending on how relevant it is to research question –> validty

Outliers:
-Straightlining (giving same response to all questions, take into account completetion time
-Are they real outliers?

Q

Meta-anaylsis

A

Should only be done in the context of final step of a systematic review (but optional step)

30
Q

Types of statistics: descriptive and infernetial

A

Descriptive:
sumarrise and desrcibe data set
Concrete and known values

Inferential:
Use probability to infer/ draw conclusiosn about larger population from smaller samle data
Abstract/estimated

31
Q
  1. Nominal
    (Levels of measurement of data)
A

Just names categories eg gender, age, monolingual etc

32
Q
  1. Ordinal
    (Levels of measurement of data)
A

Categories and their RANK
Eg 1st, 2nd and 3rd place or
disagree, slightly disagree, agree etc

But “distance” between values are not known
eg whether 1st and 2nd place were 1s or 10s apart

33
Q
  1. Interval
    (Levels of measurement of data)
A

Categories are ranked on a SCALE
So the quantities are meangful because you know the interval between them and greater range of stats can be calculated

34
Q
  1. Ratio
    (Levels of measurement of data)
A

Categories are ranked, on a scale and has a TRUE ZERO, but there is no negative values
eg height

Can be used in ratios

35
Q

Discrete and continuous data

A

Discrete: Nominal and Ordinal
Dataset has fixed number of values
Eg categories monolingual and bilingual or on likert scale 1 2 3 4 5 and no 1.5

Continous: interval and ratio
theoretically there are an infintie number of values.

36
Q

What do descriptive statistics describe

A

-central tendency: most typical/represntaitive socre
-dispersion: how much do values vary around central value

oImportant to look at and rpeort both

37
Q

Mean:
(Measures of central tendency)

A

Most senstive measure–> senstibe to outliers

Eg averga incoeme in UK will seem inflated if you take into account the few billionaires and caluclate the mean. Real value will lie somewhere closer to the median value

Thats why its important to visualize your data!

38
Q

Median
(Measures of central tendency)

A

Point/value that divides data values in equal halves

39
Q

Mode
(Measures of central tendency)

A

Value that occurs most often

40
Q

Range
(Measures of spread/dispersion)

A

difference betwen highest and lowest value

41
Q

Interquartile Range, IQR
(Measures of spread/dispersion)

A

Box plot–>
Line up data into fourths
Lower quarter and upper quarter together make the interquartile range, this accounts for 50% of values

The outliers are added to the box in the form of “whiskers”

42
Q

Variance
(Measures of spread/dispersion)

A
  1. Calculate mean
  2. Each value - mean
  3. Square value from step 2.
  4. Add up all the values
  5. Divide by the number of values - 1

hard to interpret because doesnt show spread in terms of original units

43
Q

Standard deviation
(Measures of spread/dispersion)

A

Is the square root of variance

Get better sense of spread of values than with variance

The larger the SD, the larger the variance/ data is more dispersed

44
Q

Normal distribution

A

Mean, median and mode are the same value
Most interval meausures should produce normal distributed data

45
Q

Skewness

A

Measure of asymmetry in a distribution
Positive skew = less values at the positive end, values clustered at negative end
Negative skew: less values at negative end, values clustered at positive end

Central tendency will be further in the direction of the skew : mean> median > mode

In box plot, median line will no longer be in the middle

46
Q

Kurtosis

A

Refers to the PEAK and DISPERSION of the data–> how “squished” it is

Platykurtic (“flat) : values are more dispersed so curve is flatter
Leptokurtic (“lept”) : distriution is more peaked

47
Q

Probability

A

Number of ways the event could arise / number of possible outcomes

In statistics, probabilty expressed from 0 to 1
1 = 100%
0.5 = 50%
0.05 = 5%

48
Q

Factors leading up to qualitative research

A

Epistemology–> what is knowledge
Making observations, gathering very many of them and then coming up with a conclusion

Positivism: Observations reflect reality

Can we as scientists observe the truth?

Post-positivism: the truth is out there as long as we develop a good enough questionnaire/experiment

Limitations:
-no matter how good the experiment, you cant make an unbiased judgement
-importance of context
-truth and experiences are not culturally relevant around the world

49
Q

Constructionism and Contextualism

A

Constructionism: Our perception of reality is very much determined by our community/social factors

Contextualism: Truth is not universal and its relative to context

Eg take an image of a sportsperson, crop out the body and only keep face–> without its entire context its doesnt give the same impression so a different judgement is easily made

50
Q

What is Qualitative research

A

Shift away from positivism
Use naturalistic setting where people express their views and thoughts that researchers can anaylse

-Inductive research

-Through interviews, focus groups, diaries etc

-Experiential–> naturally occuring beliefs, behaviour and narratives

-Take as long as necessary

-Rich, detailed knowledge of topic area (not limits to how much you can gather unlike quantitative which has strict limits according to the hypothesis)

51
Q

Phenomenology
(Qualitative approaches)

A

Interested in how people experience a particular phenomena–> interested in their personal perception, how did different people perceive the same thing?

how does the chocolate bar taste to you?

52
Q

Grounded Theory
(Qualitative approaches)

A

You have/start with a general question, then you collect more and more data

Inductive approach: focus group arrives, you look at inital data. Keep gathering data that gets more and more specific until you get a to a specific quesition. You build you data from the intial focus group

The goal of grounded theory is to develop a theory that is grounded in the data, rather than being imposed on the data from a preconceived theoretical perspective.

53
Q

Discourse Analysis
(Qualitative approaches)

A

Focus on language
HOw does language construct our social reality: HOW people say things, how LOUD theyre speaking, their TONE etc–> minute details of language and behaviour

54
Q

Small q or Big Q

A

Small q: quantitative questionnarie but with open ended questions

Big Q: open ended, inductive recount/exploration and experience

55
Q

Qualitative research process

A

1.Planning
Literature review
Rationale
Ethical approval

  1. Data COllection
    Recruitment
    Organise focus groups/ interviews
    transcription
  2. Data Analysis and write up
    Coding
    Data anaylsis
    Reflective anaylsis
    Full report
56
Q

1.Experience
(Different types of Qualitative Research Questions)

A

People from a particular group talk/recount their experience of something related to this “group” they belong in

Eg how do service users with BIPOLAR DISORDER experience RECOVERY and SELF MANAGEMENT

57
Q
  1. Accounts of practice
    (Different types of Qualitative Research Questions)
A

exploring and understanding how individuals or groups carry out specific activities, tasks, or practices within a particular context.

58
Q
  1. Understanding/Perceptions
    (Different types of Qualitative Research Questions)
A

How people UNDERSTAND their own experiences and PERCEIVE the world around them

Eg how do unusual sensory experiences affect people with AS (austism spectrum) in their lives

59
Q
  1. Influencing Factors
    (Different types of Qualitative Research Questions)
A

Asking people more directly “what do you think impacts your decision to …”

Eg factors that influence parents’ food purchasing behaviours

60
Q
  1. Interviews
    (Qualitative Data Collection)
A

A conversation with a purpose
not question-answer question-answer but a flowing conversation.

-Specialized and specific sampling:
Not randomized because questions can be very specific to sample and if eg backgrounds of participants is very differnet its hard to be cohesive

Ethical issues: Sensitivity, confidentiality and allowing participant to guide researcher into whatever they feel comfortable talking about. Questions should be relevant to research but also not too intrusive

Transcript: Word for word recording. Can takw this back to particiapnt and ask if they are okay/comfrotable with it being in the research

Reflexivity: Work out if you as researcher have been biased, log your challenges, how you felt, did you mb agree to heartily to smth they said because it was smh u also felt strongly about etc

61
Q

Conducting the interview (Qualitative Data Collection)

A

Wording question in a way that feels conversational and relaxed and starting the interview with general questions (not necessarily to do with research question yet)

Indirect questions: “what do you think other people might think of…” and they might follow up with their own experience

Allow silence, give time to think about answer and good active listening! Playback what you think the person is saing to make sure youve understood them corrwctly and they have a chnace to answer you

Prompts can also be used rather than questions: Photoelicitation oe vigenttes

62
Q

Problems/struggles : Interviews
(Different types of Qualitative Research Questions)

A
  • participant can go off topic and make the whole interview about a specific topic that they are very passionate about, making it difficult for you to steer towards the quesions towards the research quesiton you want
  • time and resource intensive
63
Q

Focus Groups
(Different types of Qualitative Research Questions)

A

Recorded group interview

Study the social interaction, where interviewer is faciliatator

Good for conscinetiousb ess issues where people dont agree and you can see how responses are elicited and expressed–> do views get modified through group discussion?

Naturalistic social interaction (bit researcher has less control so have to be careful abou going off on tangents)

64
Q

Pros and Cons: Focus Groups
(Different types of Qualitative Research Questions)

A

+Good for conscinetiousness issues where people don’t agree and you can see how responses are elicited and expressed–> do views get modified through group discussion?

+Naturalistic social interaction
-Researcher has less control so have to be careful about going off on tangents)

+Efficient because you can get data from 4-6 people
-can be difficult to transcribe: who is speaking?

+Empowering for people, collective sense
-People, especially when they dont know eachother, have a higher tendency to agree with eachother rather than have a discussion about it

65
Q

Online Interview and Focus Groups
(Different types of Qualitative Research Questions)

A

+ better accessibility
-technical hitches, making it less naturalistic than face to face

Synchronous and Asynchronus

Audio/Visual

Text

66
Q

Diaries
(Different types of Qualitative Research Questions)

A

Record experience over a period of time. Clear instructions that diary entry completed at specific intervals and as repsonses to certain events

+Ppl recounting their feelings in the moment rather than reflecting on it later on

Disadvtange:
Drop out rates higher
No control/idea of environment of person while writing

67
Q

Online data collection
(Different types of Qualitative Research Questions)

A

+ access larger amount of people
+Talking about sensitive issues is easier because anonymity
+practical and accessible

-trustworthiness: do people really meet the screening charactersitics/what reseacher is searching for
-digital divide: no access to people thjat dont have access to online survey eg more likely to get info on people who are more well off and younger generation who know how to use tech

68
Q

Ethics and qualitative research

A

-Participatory Approach: Generally in positivist/quantitive research ur the expert.
Participant is the expert in the qualitative approach–> they have made the experience of a certain situation so they know more about it that u do. “Partnership between participant and researcher” , they’re more involved less passive

Informed consent: at the end to check in and ask if they’re still okay with the data they have produced to be used. Consent at the beginning and at the end of experiment/interview

Anonymity: not just about removing their names, but also about other people, places etc that are mentioned because they can be recognized

69
Q

Qualitative data anylsis

A

Whatever method u use to collect data your gather, you’re making a story/ narrative

Starts with research question
Then data collection (through whatever methods/means u decide to use)
With this data, regardless of the research question or method used, you’re creating a NARRATIVE or story
Text to data (transcription happening) and then PATTERN BASED ANALYSIS: similarities, differences that come up again and again in the text to identify themes and sub themes

70
Q

Transcription

A

Orthographic: Everything that has been said and who said it
Jeffersonian: what was being said and how (voice goes high, how they laugh etc)

No correction of incorrect grammar, include all the “ums” and “ah” and “like”s

Engaged with making transcript as soon as possible so you can pick it up correctly

71
Q

Grounded Theory Anaylsis

A

You have resrach question but not many prior assumptipns as to what youre going to find.
Line by line with data and see what patterns are emrginng

Transcipt– line by line coding– focused codes (codes relevant to research question)– neagtive sampling l(ooking for evidcne against that code)– theoriteicyl

72
Q

limitations of qualitative research

A

difficult to replicate

lack of transparency

practical challenges
