Title: Qualitative Research
1Qualitative Research
- Interviews
- Observation
- Focus Groups
- Diaries/Journals
- Triangulation of Multiple Methods
- draw on strengths of individual methods to
examine phenomena from a variety of perspectives
(e.g. interviews diaries participant
observation) - Case Study Methodology commonly used
2Focus Group Interviews
- A small group of people (or several small groups)
who have been chosen based on a particular
characteristic - The interviewer asks a small number of questions
on a topic in order to explore the participants
perceptions/ideas - Heavily used in market research to test peoples
reactions to a product/service - More useful than questionnaires for in-depth
responses - Can be used with other techniques
3Case Study Methodology
- May focus on individuals, organizations,
departments/teams - Purpose to understand phenomena within a
particular context - Cases to be studied constitute purposive sampling
- May use a wide variety of techniques (interviews,
questionnaires, observation)
4Observation a Survey Methodology
- Descriptive, quantitative research
- To examine/document the world as it is (What is
happening? How often does it happen?) - Typically uses checklists, log analysis, etc.
- Exploratory, qualitative research
- Ethnographic approach typically with
interviews, etc. to document the natural setting
where behaviours occur as part of larger
investigation of individuals perceptions - Typically uses video/photos, etc.
- Or a bit of both!
5Where do Observational Methods Fit?
- First step what do you want to know?
- To map the social activity space of the library
- To watch patrons in the moment as they engage
in tasks - Focus here typically on what is actually
happening in a particular space - To document what/where/how research questions
related to patron/staff activities - Context for quantitative data (e.g.,
questionnaires) - Context for qualitative (why) questions (e.g.,
interview) - Original data for GIS mapping or other
visualization techniques - To document taboo or other activities (e.g.,
eating defacing books) that are difficult to
gather
6Observation Different Approaches
- Overt Methods
- Individuals are aware that you are gathering data
- Signs posted at door alerting individuals to
study under way - Individuals asked to engage in an activity (e.g.,
computer search) which will be videotaped - Researcher may be engaged in activity under study
- Covert Methods
- Individuals are not aware that you are gathering
data - Researcher as disengaged observer who documents
and reflects on activities going on in the
library - Researcher as engaged observer, but participants
unaware they are being studied
7Data Collection Tools of the Trade
- Observation Checklists Journals (paper vs.
digital) - Created in advance to guide observation
- Created during field notes of what is
happening in the space - Digital video/photographs (is audio required?)
- Of spaces, alone or of patrons
- Of computer screens, storytime groups, etc.
- Maps (paper vs. digital)
- Hand-drawn vs. blueprints
- Analysis software
- Quantitative Excel, SPSS, etc.
- Qualitative (including images) Atlas.ti
- GIS visualization ArcGIS

14Seating Sweeps Method
- Observational walks (or sweeps)
- 3 times per day over a one week period
(1015-1130am 2-330pm 6-730pm) - Covered all library spaces separate floors,
café area, circulation desk, etc. - Systematic detailed observations of 60
different variables - Who is present in specific locations? What are
they doing? What possessions do they have with
them?
15Seating Sweeps contd
- First step scour library space to develop
locational acronyms - CW computer workstation
- BT book truck
- Second count seats in/outside library space
- Benches, sofas, carrels, worktables, etc.
- Photos/maps of spaces (with/without patrons)
- Third develop coding worksheet
- Academic library settings used PDA for this
task, so also needed to pilot test equipment - Benefit much less obtrusive and easier to prep
for analysis - Downside more time-consuming, up-front
16Sweeps Method Issues
- Daily debriefing re codes
- E.g. searching vs. physical searching
- Differences between sites
- E.g. VPL cellphone-friendly zone
- Unobtrusive?
- Us watching them vs. them watching us
- Individuals in motion
- People leave, pick up new books, start to talk to
the person next to them, etc
17Individuals Activities in Library
18How Might we Extend Sweeps?
- Use furniture counts (quantitative) to determine
- How much of the library seating space is actually
being used? - How are patrons using that space sleeping?
Staying all day? Do these trends vary by location
in library? - Observational shadowing following patrons
throughout their visits (qualitative) - Mapping data with GIS to compare patterns
across floors, across time periods, etc. - Active use of photos to paint a full picture
of the spaces and activities under study
19Bringing Data to Life
- Alex 2nd year, Business/Commerce
- When Im really trying to study, I like the
reading room in Rutherford, that big room with
paintings on the wall, at the top. I think for me
its almost like an historical sense and I almost
have like a duty to study in there, you know?
Its just kind of that atmosphere in there so
thats where I go to really studyI think its
pretty open and its quiet in there, theres
space for you to go at the tables, spread all
your work out, youre not like at a little,
little desk thing
20A Photo tells the Story
21Why Use Observational Methods?
- A snapshot
- Who are our patrons? What are they doing in the
library? - A chance to see what patrons really do
- How do staff interact with patrons (or one
another) in the library space? - This information is invaluable for
- Allocating staff within the library
- Determining financial support
- Organizing furniture (re)designing library space
22Sampling Access
- Always start by thinking about the population you
wish to study then make decisions about sample
selection - Will you study the population or a sample?
- How will you find participants/documents and
can you gain access? - Target population the population to which you
would like to generalize or transfer results - All librarians or only those in academic
settings - All teenagers or only those with diabetes
23Sampling Frame
- The set of all cases from which the sample is
drawn - 2 ways to construct this frame
- (1) listing all cases
- e.g. directory of academic librarians
- (2) providing a rule to define membership
- e.g. teenagers diagnosed with diabetes during
early teen (13-15) years - How many participants?
24Non-probability Sampling
- Convenience Sampling
- Individuals chosen who are available or easy to
find - Give questionnaire as people enter the library
- Purposive Sampling
- Each sample case is selected for a purpose
because of its unique position - A typical rural library a typical urban
library - Quotas set so sample represents certain
characteristics in population - LIS programs 80 female, 20 male
- Snowball Sampling
- Identify one member of the population and get
that individual to identify others
25Probability Sampling
- Simple Random Sampling
- Each case in the population has an equal chance
of being included in the sample - Systematic Random Sampling
- First case is randomly selected, then every nth
case - Stratified Random Sampling
- Population is first subdivided into 2 or more
strata based on mutually exclusive categories
of one or more relevant variables (e.g.,
male/female) - Simple random samples are then drawn from each
stratum, and these sub-samples are joined to form
the complete stratified sample
26Probability Sampling (2)
- Cluster sampling
- The population is broken down into groups of
cases (called clusters), and a sample of
clusters is selected at random - The clusters generally consist of natural
groupings (e.g. geographic - city blocks
organizational library branches in one city)
27Quality Research - Criteria
- Quantitative
- Validity
- Generalizability
- Reliability
- Objectivity
- Qualitative
- Credibility
- Transferability
- Dependability
- Confirmability
28Quantitative - Validity
- The degree to which you are truly measuring what
you intend to measure - E.g. Hawthorne Effect (Study of productivity at
an Electric company) - Looking for evidence that a particular
independent variable (e.g. bright lights) has
caused a change in an observed dependent variable
(e.g. productivity) - Use control groups triangulation of methods
focus on operational definitions
29Qualitative - Credibility
- Does the description developed through the
inquiry ring true for members of the group
under study? - Assessed through - prolonged engagement,
persistent observation, triangulation, assessment
of contextual materials, peer debriefing, member
checks
30Quantitative Generalizability
- The ability to generalize findings across
different settings or populations - Asks whether the results of the study apply to
cases not included in the study - E.g. study of MLIS students use of OPACs not
generalizable to the general population, as
library students have special knowledge - Select sample carefully repeat measure
(different setting/time of day/etc.)
31Qualitative Transferability
- Can the findings be applied in other contexts or
with other respondents? - Key to focus on those elements which will not
shift with context/time (and recognize
limitations of context/time to your findings) - E.g. will Canadian studys findings transfer to
U.S. context?
32Quantitative - Reliability
- Will the research yield stable, consistent
results when applied repeatedly? Can the study
be replicated? - E.g. How many books have you borrowed this
year? may be unreliable they may not recall
the exact (so they guess) they may feel that
they should have borrowed more books (so they
inflate ) - Use pilot studies interviewer training apply
measure consistently etc.
33Qualitative - Dependability
- If the study were replicated with the same (or
similar) respondents in the same (or similar)
context, would the findings be repeated? - Key not looking for invariance but for
trackable variance - that if there are
inconsistent findings, these are attributable to
particular sources (e.g. reality shifts, better
insights)
34Quantitative - Objectivity
- Quantitative measures are value-free and
therefore objective - Key here idea that subjectivity leads to
results that are both unreliable and invalid - Eliminate sources of bias and error that may
distort results - E.g. use several, independent observers withhold
information from participants to not taint
opinions tape record events etc.
35Qualitative - Confirmability
- Researcher as Instrument
- The degree to which the findings are the product
of the focus of the inquiry and not of the biases
of the researcher (i.e. key neutrality) - Not to ensure that data is free from
contamination (as objectivity is an illusion),
but to show that the data (assertions, facts,
etc.) can be tracked to their sources - E.g. inter-coder checks on interview data
