3The Premise of this Paper
- There are many standards for surveys examples
include - ISO 20252 for Market, Opinion and Social Research
- OMB standards
- NCES statistical standards
- Quality guidelines developed by specific
organizations (Stat Can RTI etc.) - ESS Code of Practice
- Do these standards help in reducing total survey
error for surveys? - The answer to this question is not clear.
4Definitions policies, standards, guidelines and
recommended practices.
- standards - A practice that is followed almost
without exception. Deviations are not
recommended and require approval of senior
management. Corrective action should be taken
when a standard is not being met. - policies (no exceptions under any circumstances)
- guidelines (can be skipped for good reasons),
and - recommended practices (promoted but not
obligatory) - Colledge and March (1997)
5What are survey standards?
- A document that
- describes methods and procedures for the
collecting, processing, storing, and presenting
survey data. - define the (minimal) level of quality and effort
that is acceptable for all survey processes - May address only some survey processes e.g.,
standards for writing survey reports - Should be auditable vague standards have no
effect on survey quality
6What purposes do survey standards serve?
- Communicates a level of quality that
organizations establish as minimal for all
surveys. - Provide consistency across surveys in different
organizations - Facilitate communication of complex concepts,
formulas, procedures and methodologies - Provide transparency of the methodologies used to
produce a survey data set. - Transfers skills and knowledge of best survey
practice
7Some Problems with Survey Standards
- Comprehensive standards can overwhelm survey
practitioners - Unless mandated and audited, they are largely
ignored. - Must be continually updated.
- May conflict with client requirements.
- Can be costly to develop, maintain and enforce.
- No documented evidence exists that they improve
data quality.
8Idea advocated in this presentation
- General survey standards have their strengths and
weaknesses, but their effects on data quality
have not be documented - Instead we advocate Standards for Survey Quality
Investigations (SSQIs) - SSQIs are like survey standards in that they
describe methods and procedures. - SSQIs focus on methodological studies and survey
quality investigations. - Example the AAPOR standard for computing
response rates.
9What purposes would SSQIs serve?
- To promote data quality investigations.
- To encourage sharing of the results of survey
methodological studies, including the data
themselves. - To communicate the methods and the quality
metrics used. - To facilitate methodological meta-analysis and
comparative analysis - To increase transparency and consistency
- To share skills and knowledge regarding survey
quality investigations. - Decrease process variation
10Some areas where SSQIs would be beneficial
- Computation of frequently used quality indicators
- weighted and unweighted response rates (e.g.,
AAPOR) - eligibility rates
- tracing rates
- frame coverage, duplication, and erroneous
inclusion rates - design effects (unequal weighting and clustering)
- keying, coding and editing error rates
- Item nonresponse rates
- reliability measures
11Some areas where SSQIs would be beneficial
(contd)
- Reporting standards for these quality indicators
- Best methods for collecting data to compute these
quality indicators - Best practices for
- Nonresponse followup studies, including two phase
sampling methods - Investigations of interviewer variance
- Evaluations of frame coverage bias
- Reinterview studies
- Experimentation with incentives
12Resurrecting an old ITSEW idea Survey Quality
Wiki
- Wiki Hawaiian for fast backronymed to
stand for what I know is - Website that allows the easy creation and editing
of any number of interlinked web pages via a web
browser using a simplified text editor - Typically powered by wiki softwareto create
collaborative websites for knowledge management. - Users use their editorial rights to remove
material that is considered "off topic." Such is
the case of the collaborative encyclopedia
Wikipedia.
13Questions for Discussion
- How does the group feel about survey standards in
general? - How well do they serve their stated purposes?
- Are there good examples of cases where they have
improved survey quality? - How does the group feel about SSQIs? Would such
standards benefit survey quality research? - What types of SSQIs would be the most beneficial
for survey research? - How should SSQIs be promulgated? Is a Survey
Quality Wiki a good idea? Is there interest in
developing it?
