Designing a Qualitative Study continued...How
might you be wrong?How will you explain and
justify your study?WEEK 5 September 25, 2003
  • Discussion of Maxwells Qualitative Research
    Design Chapters 6 7
  • Writing a Research Proposal-- Discuss this
    process in detail
  • Lab 3 DUE Each student presents her work (begin
    with other half)
  • Lab 4 Participant Observation Handed out due
    October 9 (not next week)
  • Reminder --- Research Proposal Due next week
    October 2

Validity How might you be wrong?
  • validity threats and what you can do to answer
    the question
  • Why should we believe you?

8
validity threats
  • a way you might be wrong
  • rival hypotheses
  • alternative explanations

9
validity is a goal rather than a product
  • validity threats are made implausible by EVIDENCE
    not methods methods are only a way of getting
    evidence that can help you rule out these threats
  • ALL fieldwork by a SINGLE fieldworker invites the
    question, Why should we believe it?
  • you only have to get to a turtle you can stand on
    securely

10
types of validity threats for each type of
understanding
  • description inaccurate and incomplete data
  • interpretation imposing ones own framework
  • theory not paying attention to discrepant data
    or not considering alternative explanations or
    understandings of the phenomena you are studying

11
TWO SPECIFIC types of validity threats
  • researcher bias select only data that fits your
    theory or select data that stands out to the
    researcher
  • reactivity influence of researcher on the
    setting or individuals

12
validity tests a checklist
  • triangulation collect data from a diverse range
    of individuals and settings using a variety of
    methods
  • feedback get feedback from a variety of people
    ESPECIALLY, member checks
  • rich data collect data in a detailed and
    complete manner--audiotape and videotape for
    later transcription and analysis
  • quasi-statistics amount of evidence that bears
    on particular threat
  • comparison with other research, with previous
    experience

13
generalization in qualitative research INTERNAL
GENERALIZABILITY refers to the generalizability
within the setting or group studied. EXTERNAL
GENERALIZABILITY refers to face
generalizability--there is no obvious reason not
to believe that the results apply more generally
but qualitative research is not BY DESIGN the
most useful approach for external
generalizability probability sampling is much
more precise.

Research Proposal
  • your research design will evolve as you conduct
    your study, and therefore a proposal for a
    qualitative study cant present an EXACT
    specification of what you will do...

18
Research Proposal
  • Explain
  • Justify
  • Your Proposed Study
  • Nonexperts
  • The proposal is an argument for your study
  • Needs to explain the logic behind the proposed
    study
  • Not simply describe or summarize the study

19
Research Proposal
  • What are we going to learn as the result of the
    proposed study that we dont already know?
  • Why is it worth knowing?
  • How will we know that the conclusions are valid?

20
Sample Research Questions
