1primary data definition
data collected by or for researchers at an event that is observed or recorded
2secondary data definition
Written sources that make sense of summarized primary data
3primary data types
Observation: records, usually of events, situations or things, of what you have experienced with your own eyes
Participants: data gained ny experiences that can perhaps be seen as an intensified form of observation
Measurements: records of amounts or numbers
Interrogation: data gained by asking and probing
4secondary data types
Academic journals, news broadcast, magazines, newspapers, documentaries, advertising, internet
5theory
the abstract statements that make claims about the world and how it works. Research problems are usually stated at a theoretical level
6concepts
the building blocks of the theory which are usually abstract and cannot be directly measured
the ideas or mental representations of things
nominal: describes the concepts in rods, much like a dictionary definition
7indicators
the phenomena which point to the existence of the concepts
Tell us that there may be a link and indicate how strong that link may be
Usually, one indicator for each concept is adequate
It is advantageous to use more than one indicator of a concept
8Using multiple-indicators (variable) to measure a concept
Ensures the definition of the underlying concept is understood correctly
Gets access to a wider range of issues related to the concept, allows the researcher to make finer distinctions
Allows for factor analysis and cluster analysis
Helps to weed out response sets
9variable
Variables can be measured indicators by specific questions in a questionnaire
Independent variables are manipulated to see if they have an impact on dependent variables
10values
the actual units or methods of measurements of the variables. These are data in their most concrete form
11coding unstructured data
Coding unstructured data
Derive codes: labels or title given to the themes or categories
Assign numbers to the codes
Basic principles to observe
Categories must not overlap
Categories must be exhaustive
There must be clear rules for how codes are applied
12reliability
Stability over time
Internal reliability- Are you doing the same thing every time
Inter-observer consistency
13measurement validity
concerned with whether one is measuring what one wants to measure
14face validity
Established if, at first glance, the measure appears to be valid
15concurrent validity
Established if the measure correlates with some criterion thought to be relevant to the concept
A lack of correlation brings some doubt onto the validity (correctness) of the original measure
16construct validity
established if the concepts relate to each other in a way that is consistent with the researcher’s theory
This is confirmed by seeing that the results match what would be predicted given the theory
17convergent validity
Established if a measure of a concept correlates with a second measure of the concept that uses a different measurement technique
18criticism of quantitative
people and social institutions are treated as if they are part of the world of nature
The measurement process produces an artificial and false sense of precision and accuracy
The reliance on instruments and procedure produces a disjuncture between research and every day life
An analysis of relationships between variable ignores peoples everyday experiences and how they are defined and interpreted
Explanations for findings may not address the perceptions of the people to who the findings purportedly pertain
Quantitative researches tend to assume an objectivist ontology
19simple random sample
Where each element has the same probability of being selected & each combination of elements has the same probability of being selected
Sampling ration: n/N (sample size:n, total population: N)
20systematic sample
For every ith case in the sampling frame is selected
i= size of sampling interval
Eg: you want to select every 30th case, i=30
21stratified random sample
This type of sampling ensures that subgroups in the population are proportionally represented in the sample
Select a simple random sample or a systematic sample from each stratum
22multi-stage cluster sampling
Used for large populations
It involves 2 or more stages
Selecting clusters (groups of elements)
Then selecting subunits within clusters
23types of nonprobability sampling
accidental (convenience)
quota- a specified number of cases in particular categories to match the proportion of cases in that category in the population
Theoretical- Is a useful method of getting information from a sample of the population that you think knows most about a subject. A study on homelesslness could concentrate on questioning people on the street. T
purposive- selects what they think is a ‘typical’ sample based on specialist knowledge
systematic matching- when 2 groups of very different size are compared by selecting a number from the larger group to match the number and characteristics of the smaller one
snowball- The researcher makes contact with some individuals, who in turn provide contacts for other participants
24structured observation sampling
no sampling frame, involve time sampling, place sampling, behaviour sampling
25sampling error
definition matters
About 95% of all sample means lie within 1.96 standard errors of the mean
sampling- related error
data collection error
data processing error
26sample size
As a sample size increases, sampling error tends to decrease
Common sample sizes: 100, 400, 900, 1600, 2500
Each size increase cuts the sampling error by ½, then ⅓, then ¼, and then ⅕ respectively
The biggest change occurs between 100 and 400
27criteria for assessing secondary data
authenticity
credibility
representation
meaning
28secondary data- advantages
Low cost
Less-time consuming
Opportunity for longitudinal analysis
Subgroup analysis often possible
Opportunity for cross-cultural (international) analysis
More time for data analysis, since no time is spent gathering data
The data can be reanalyzed
Fulfills wider obligations of the social researcher
29secondary data limitations
Lack of familiarity with the data
Complexity of the data
No control over data quality
Absence of key variables
The ecological fallacy may become part of the analysis- This occurs if the unit of analysis for a statement or hypothesis is not the same as that for the data
30open question advantages and disadvantages
Advantages:
Allows for replies that the survey researcher might not have contemplated
tap the participants unprompted knowledge
Disadvantages:
More time consuming
Answers must be coded
Face inter-interviewver variability
31closed questions- advantages and disadvantaging
Advantages:
Minimizes intra-interviewer variability
May make it easier to understand question because the answers are provided
Disadvantages
Loss of spontaneity and authenticity
differ in their interpretation of wording of fixed questions
32post coding
data are gathered, and then themes or categories of behaviour are discerned
Eg an open questin on the legalization of marijuana might have codes ‘very hostile opposition’, ‘indifferent’, etc
33pre-coding
Themes or categories of behaviour are decided upon before the data are gathered
Eg “what is your view on the legalization of marijuana? Are you strongly opposed, neither opposed or in favour, in favour or strongly in favour?
34coding questions
It involves making themes of categories of behaviour to form the basis for codes (labels or titles given to the themes or categories)
These themes are derived from the collected data
353 principles for coding in research
1. The categories must not overlap
2. All possibilities that exist in the data must be exhausted
3. There should be clear rules for what is included in categories and what types of answers relate to each categories
36types of questions
Personal factual questions
Factual questions about others
Factual questions about entity or event
Questions about belief
Questions about knowledge
37vignette questions
presenting people with one or more scenarios and asking them how they would respond
Anchor the choices in a realistic situation
Creates distance between question and respondent
38run a pilot study
Used to test whether individual items or the instrument as a whole operates well
open questions to generate closed questions
interviewers with experience in administering the instrument
ensure that there is variability in the answers given
39structured interviews
a formal list of questions that the interviewer must follow in detail
The questions must be asked in the order given
produce standardization
40intra-interviewer variability
an interviewer is not consistent in asking questions or recording answer
41inter-interviewer variability
lack of consistency in asking questions or recording answers between different interviewers
42semi-structured interviewer
The researcher has a list of questions or topics to be covered
interviewee s are free to reply in any way
Can ask questions out of order
New questions may be devised and asked on the spot
useful when more than one interviewer or interviewee
43unstructured interviews
The researcher uses only a brief set of points to introduce topics
The only thing defined is the broad topic of interest
Conversational
44kinds of questions
Introducing questions
Follow-up questions
Probing questions
Follow up what has been said through direct questioning.
Specifying questions
‘What did you do then?’
45direct vs indirect questions
direct: ‘Do you find it easy to eep smiling when serving customers”
Best left until later in the interview,
indirect: (how do you feel about…?) and then “what do most people around here think of the ways that management treats its staff?”
46telephone interviews strengths and weaknesses
Strengths
Cheaper and quicker to administer,
Reduced issue with confidentiality
Reduced bias arising from ‘interviewer effect’.
Weaknesses
Hard to sustain for long periods of time (20–25 minutes).
Personal interviews tend to be more effective with sensitive issues.
47complete observer
the observer takes a detached stance by not getting involved in the events and uses unobtrusive observation techniques and remains ‘invisible’ either in fact or in effect (ignored)
No bias
48observer-as-observant
the researcher is mainly an interviewer doing some degree of observation but very little participation
49participant-as-observr
the researcher engages fully in the life and activities of the observed, who are aware of their role
50complete participant- cohort observer
the researcher takes a full part in the social events but is not recognized as an observer by the observed- cohort observer
Full biases
51ethnography
the study of people and their culture in naturally occurring settings
Behaviour is observed in an unstructured way by carrying out in-depth discussions and interviews with the people studied
52re-classification
The process that aggregates data at the current or lower level of measurement in order to reduce the data amount and achieve satisfactory analytical quality
Age→ age cohorts
53sectorial and spatial aggregation
Sectorial aggregation
Grouping variables values based on the values of another variable
Spatial aggregation
Census tracts make up neighbourhood
Boroughs figured summed or averaged by census tracts
54contigency tables
Allow for simultaneous analysis of 2 variables
Identify patterns of association
Normally used for nominal or ordinal data
55nominal
the difference that exists between participants is being in one category or another
Categories can not be ordered by rank
ex gender
56ordinal
the categories of the variable can be rank ordered
Distance or amount of difference between categories may not be equal
Cannot do arithmetic or mathematical operations with the categories
Eg high enthusiasm, moderate enthusiasm and low
57interval/ ratio
distance or amount of difference between categories is uniform
Can do arithmetic and mathematical operations with the categories
Ratio variable have a “0” start position
58univariate analysis
Analysis of 1 variable at a time
Combining categories makes the data more manageable
Diagrams can be used to illustrate frequency distributions
Use bar charts and pie charts for displaying a nominal or ordinal variable
Use histograms for interval/ ratio variable
59Contingency tables (cross-tabulations)
Allow simultaneous analysis of 2 variables
Identify patterns of association
Normally used for nominal or ordinal data
60pearson's R
Normally used with interval/ ratio
Values from 0 (indicates no relationship)
To +1 (perfect positive relationship)
Or -1 (indicates perfect negative relationship)
61kendall's tau-b
Shows correlation between pairs ordinal variables or with one ordinal and one interval/ ratio
Like Pearson’s R, values range from o to +-1
62spearman's rho
Shows correlation between pairs of ordinal variables
Like Pearson’s R, values range from o to +-1
Will predict a rank position from one variable to another
63cramer's V
Shows the strength for the relationship between 2 nominal
Range 0 to 1
Nominal categories cannot be rank ordered
Usually reported with a contingency table and a chi-squared test
64amount of explained variance
Eta, Kedalls’s tau-b, Spearman’s rho, Pearson’s R
Squaring sows how much the variation in 1 variable will explain variation in the other variable
Allows prediction of the 2nd variable based on the score from the 1st
65statistical signifiance
Can a sample finding be sued to estimate a characteristic of the whole population
Stated as probability level
The probability that the results are not due to change
A null hypotheses tets the significance of the bivariate association
66bivirate analysis
all of these prove relationship and not causality
67type 1 error
rejecting a true null hypothesis
The results are a chance association
68type 2 error
not rejecting a false null hypothesis
69Statistical significance- chi squared
Used with contingency tables
Measure the likelihood that a relationship between the 2 variable exists in the population
Calculated by comparing the observed frequency in each cell with what would be expected by chance
The x^2 value is affected by the sample size
70Statistical significance- Comparing means
Analysis of variance (F statistic)
Total amount of variation in the dependent variable
Indicates there is a reduced likelihood of no relationship between the set of independent variables and the dependent variable
Reported as a statistical significant probability (p)
71Comparing means and statistical significance
Analysis of variance (F statistic)
Total amount of variation in the dependent variable
there is a reduced likelihood of no relationship between the set of ind
Reported as a statistically significant probability (p)
the mean of the explained variation
in relation to means of the error variance
72analytic induction and its difficulties
A general research question is devised.
Some data are gathered.
An hypothesis is proposed.
Difficulties with analytic induction
Because all cases must be explained, the hypotheses generated may be too broad to be useful.
no guidelines on how many cases must be reviewed
73types of coding (qualitative data)- open, axial, selective
Open
Identifies initial concepts that will be categorized together later.
Axial
Data are reviewed for linkages and re-organized according to those connections.
Selective
Selection of the core category / categories
Validating the relationships
Identifying gaps that need to be filled in
74substantive theory
Observed patterns are related to each other and a theory is developed to explain the connections in that setting.
75formal theory
Theory applied at a higher level
Requires data collection in different settings
Applicable to a variety of settings
76criticisms of grounded theory
Differences between concepts and categories may be vague.
Observation and data gathering may not be as 'theory neutral' as claimed
Practical difficulties, e.g., time constraints on transcription
It may not result in theory
77primary qualitative data collection methods
Ethnography and participant observation
Qualitative interviewing
Focus groups
Discourse and conversation analysis
Analysis of texts and documents
78six classes on which to plan a coding scheme for ‘social phenomena’
Acts
Activities
Meanings
Participation
Relationships
Settings
79problems with coding
Risk of losing the context
By selecting parts of the text, qualitative coding weakens the connection between description and social setting in which the events occur
Fragmentation of data
Breaking the data into codes and small chunks of text results in a loss of narrative
80Computer-assisted qualitative data analysis software (CAQDAS)
Will sort data once the codes are defined
They don’t interpret the data
Advantages of using software:
new visual ways of looking at data
Criticisms of using software:
quantify coded text and negates the qualitative, thematic interpretation of meaning important in qualitative analysis
It fragments textual material into very small pieces of data where the natural flow of the story is broken
81narrative analysis
Researching the stories people tell to understand their life and the world
Criticism
Stories may be accepted at face value by the researcher.
1. Thematic
2. Structural
3. Interactional- Examines the dialogue (construction) between the teller and the listener
4. Performance
82content analysis
The examination and coding of docs and texts: printed visual, aural or virtual
Words, including the pairing of certain words
Subjects and themes
Value positions
What is the presentation front
83semiotics (signifier, signified, denotative meaning, connotative meaning, polysemy)
the ‘science of sign’
expose hidden meanings in text
Signifier- Thing that indicates an underlying meaning
Signified- The meaning that is pointed to
Denotative meaning- The obvious meaning of a signifier
Connotative meaning- Secondary ,eaning that arises with the denotative meaning
Polysemy- Recognizes that signs ma be interpreted differently
84hermeneutics
The meaning of a text involve the author’s circumstances and the context in which the text was constructed
Eg history- the perspective of winners vs losers in war
85conversatin analysis
Examines how social order is created through convo
Social order is an achievement not an objective pre-existing phenomenon we uncover
Focuses on reflectivity (responds to context)
Data from naturally occurring situations (naturalist)
Characteristics of how talk is organized:
Adjacency pairs- How the talk moves between praties (eg question-answer)
Preference organization- Preferred responses and non-preferred responses
Cultural contexts are not permitted- Focus is limited to words themselves
86discourse analysis
Includes elements of conversation analysis
Broader and more flexible
Cover communication other than talk
Tends toward a constructionist orientation
Discourse is a topic itself
Language is constructive
Discourse is a form of action
Discourse is rhetorically organized
87advantages and disadvantages of content analysis
Advantages
In its quantitative form it is very transparent, and therefore easily replicated
longitudinal analysis
unintrusive
Disadvantages
Limitations due to the texts analyzed
It is difficult to answer ‘why?’ questions
88interpretivism
Interest in the uses of meaning, eg those who study attitudes using surveys
Qualitative claim access to participants’ world view
Rarely proved through respondent validation
89constructionism
Quantitative methods (such as quantitative approaches to content analysis) can be used to establish how people create their sense of reality
Eg one could study the content of TV shows quantitatively to illustrate one way in which gender socialization takes places
Epistemological and ontological considerations
People using a particular research strategy do not always share the same epistemological and ontological assumptons
90Approaches to multi-strategy research- triangulation, facilitation and complementarity
Triangulation:
The use of quantitative research to collaborate qualitative findings and vice versa
2 methods to come to a conclusion
Facilitation
The use of one research strategy to assist with research that uses a different strategy
Complementarity
Using 2 or more approaches where a single approach would not be sufficient
91reflection on multi-stage strategy
Becoming more common
Multiple methods likely take more time and money
Different skills and training required
