might you be wrong?How will you explain and
justify your study?WEEK 5 September 25, 2003

7Validity How might you be wrong?
- validity threats and what you can do to answer
the question - Why should we believe you?
8validity threats
- a way you might be wrong
- rival hypotheses
- alternative explanations
9validity 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
10types 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
11TWO 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
12validity 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
13generalization 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.

16Research 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...
17(No Transcript)
18Research 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
19Research 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?
