3Types of Observational Data Acquisition
- Casual observation
- No/minimal deliberate preparation naturalistic
research - Systematic observation
- Time allocation traffic surveys scientific
measurements - Unstructured interviews
- Flexible content and flow
- Follow the flow interaction (conversation) and
probing (spontaneous?) - Driven by research questions and check lists
- Not restricted to check lists and check lists
not always completed - Life histories (time lines lists of significant
events) - Semi-structured interviews
- Flexible flow based on checklist of
questions/topics - Extensive probing for clarification and
elaboration - Resisting diversion from research questions
- Check lists answered in full
- Structured interviews
- Rigid content and flow
- Pre-worded questions administered in
pre-determined flow - Complete answering in all cases

5Use of Official/existing/others data
- Access and use (restrictions)
- Anonymisation
- Documentation of methods used
- objectively reflect reality?
- reflect organisational behaviour or actions of
individuals in institutions? - facilitate the /control regulation of the
population? - Censuses exacerbate race ..
6Problems with Surveys
- Poor sampling (no/unsatisfactory frame, poor
execution) - Too long
- Too many questions
- Too diverse topics
- Poorly worded questions
- Language/jargon
- Leading
- Poorly laid out questionnaires
- Poorly trained/poor quality interviewers
- Poor management and supervision
- Personnel management
- Archiving
- Poor cooperation/rapport
- Poorly informed/poor choice of respondents
- Problems with data processing
7Non-Sampling Errors - 1
- Errors in conception, logic, execution,
reporting, data capture and manipulation,
arithmetic, statistics, . - Bias (systematic error)
- Sampling biases and errors
- Target and sampled populations
- Access and cooperation -
- Non-sampling biases
- Incompatible meanings (are they really your
father/brother?) - Pilot studies
- Hawthorne Effects
- Was the treatment actually applied?
- Pseudo randomisation (every random sample is not
necessarily random) - Simulation from ideal populations -
computational statistics

Final data

9Non-sampling errors - 2
- Non-response and attrition
- Repeat (interpenetrating) samples (Central and
State) - partial panels (50 old 50 new households)
- Wording
- Strongly affects responses (see also leading
questions) - Cross-domain differences (space, social group,
time) - Use of standardised instrument has different
biases in different contexts (consumption) - Changing responses (timing of opinion polls,
within and between year variations, time to
evaluations)
10Response errors
- Response errors
- Telescoping and Forgetting reference periods
- Too much and too little reported
- Self-edited and self-deceiving responses
- Acquiescence bias (agreeing with the
interviewer/correct resonses, normal rather
than particular) - What people say (in particular circumstances)
- What people think
- What people do
- Position bias
- Age/number lumping selection from
(ordered/numbered) list - Triangulation
- Multiple sources (census, survey, and qualitative
inquiry) - Contested policy arenas
11registered and non-registered information
reliance on memory -
12Getting Process Right
- Relevance Accuracy
- Pre-tests notice the plural
- Rapport and cooperation
- Appropriate introduction and briefing
- Choice of respondent, anonymity, confidentiality
- Privacy
- Briefing
- Conduct
- Quick and efficient
- Taking refreshments
- Interruptions and returns
- Exit
- Affects response of others in cluster
- Affects cooperation with return checks

14Choosing the right respondent
- Has the knowledge
- And is able to recall it
- Make the appropriate calculations
- Is willing to respond
- In principle
- Is able to respond (time)
- Has the authority
- In the appropriate way at the appropriate time
15Better Questionnairs
- Length
- Complexity and diversity
- Flow
- Layout
- Size
- Space (for elaborate answers)
- Skips
- Computer aided questionnaires
- Speed of analysis
- Intrusion/suspicion
- Reliability and back-ups
16Open, closed, leading, and other questions
- Leading , etc.
- Loaded or biased
- are women paid less than men for the same work?
- Loaded context
- privacy
- interviewer bias
- Double-(or more) barrelled
- Two or more questions
- Long
- General
- Technical
- (Double-)negatives
- Closed
- do you grow the following crops? list and
check - Specific predetermined answers
- Exclusive and exhaustive resonses
- Limits responses
- allow other categories
- describe/explain/elaborate
- provide opt-out (dont know/none..
- Standardises
- restricts diversity and exceptions
- Easier to analyse
- lots of data processing and statistical problems
- Open
- no pre-determined set of answers
- Allows a range of individual responses
- Liable to interviewer bias
- Harder to analyse
- non-standard responses
- data mining
- choosing cases without regard to broader set of
responses
