The document discusses various methods of observation data collection. It describes participant observation where the observer actively participates in the group being studied and non-participant observation where the observer does not interact. It also discusses ethical issues around observing subjects without their consent. Different types of observations are outlined such as structured vs unstructured, disguised vs undisguised, and natural vs contrived. Advantages of observation include collecting actual behavior rather than self-reported data but disadvantages include not understanding why behaviors occur.

1. Data Collection: Observation
Method

2. Observation Method
The observation method involves human or
mechanical observation of what people actually do?
“Information is collected by observing process at work.”
Definition
 Observation method is a technique in which the behavior
of research subjects is watched and recorded without any
direct contact.

3. Types of observation methods
 Participant observation
 Non-participant observation

4. Participant observation
 Observer participates actively, for an extended period of
time.
 May require observer to live or work in that area.
 Assumes that observer will become accepted member of
the group or community.
 Historically field research has been associated most
strongly with participant observation.

5. Non-participant observation
 Observer is an eavesdropper.
 Someone who attempts to observe people without
interacting with them.
 Without their knowledge that they are being
observed.
 Used most routinely by psychologists studying
children and animals.

6. Ethical Considerations
 Ethical issues arise when people are being observed,
whether they are aware of it or not.
 Technological advances--cameras and microphones—
facilitate observing verbal and non-verbal behavior
that might be considered to be an invasion of
privacy, particularly if the subject is unaware of being
observed.
 Yet the information is used to make decisions that
impact the subject.

7. Should you Collect Your Data by
Observation?
Questions to consider:
 Is the topic sensitive?
 Can you observe the Phenomena?
 Do you have a lot of time?
 Are you sure of what you are looking for?

8. Types of Observations
 Observation is a method of collecting data by human,
mechanical, electrical or electronic means.
 The researcher may or may not have direct contact
or communication with the people whose behavior is
being recorded.
 Observation techniques can be part of qualitative
research as well as quantitative research techniques.

9. Observation Methods
Personal Observation
 A researcher observes actual behavior as it
occurs.
 The observer does not attempt to manipulate
the phenomenon being observed but merely
records what takes place.
 For example, a researcher might record traffic
counts and observe traffic flows in a department
store.

10. Observation Methods
Mechanical Observation
Do not require respondents' direct participation.
 the AC Nielsen audimeter
 turnstiles that record the number of people
entering or leaving a building.
 On-site cameras (still, motion picture, or video)
 Optical scanners in supermarkets
Do require respondent involvement.
 eye-tracking monitors, pupilometers
 psychogalvanometers
 voice pitch analyzers
 devices measuring response latency

11. Observation Methods
Structured versus Unstructured
Observation
 For structured observation, the researcher
specifies in detail what is to be observed and
how the measurements are to be recorded,
e.g., an auditor performing inventory analysis
in a store.
 In unstructured observation, the observer
monitors all aspects of the phenomenon that
seem relevant to the problem at hand, e.g.,
observing children playing with new toys.

12. Observation Methods
Disguised versus Undisguised Observation
 In disguised observation, the respondents
are unaware that they are being observed.
Disguise may be accomplished by using one-
way mirrors, hidden cameras, or
inconspicuous mechanical devices. Observers
may be disguised as shoppers or sales clerks.
 In undisguised observation, the
respondents are aware that they are under
observation.

13. Observation Methods
Natural versus Contrived Observation
 Natural observation involves observing
behavior as it takes places in the
environment. For example, one could
observe the behavior of respondents eating
fast food in KFC.
 In contrived observation, respondents'
behavior is observed in an artificial
environment, such as a test kitchen.

15. Observation Methods
Audit
 The researcher collects data by examining
physical records or performing inventory
analysis.
 Data are collected personally by the
researcher.
 The data are based upon counts, usually of
physical objects.
 Retail and wholesale audits conducted by
marketing research suppliers were discussed
in the context of syndicated data in Chapter 4

16. Observation Methods
Content Analysis
 The objective, systematic, and quantitative
description of the manifest content of a
communication.
 The unit of analysis may be words, characters
(individuals or objects), themes (propositions), space
and time measures (length or duration of the
message), or topics (subject of the message).
 Analytical categories for classifying the units are
developed and the communication is broken down
according to prescribed rules.

17. Observation Methods
Trace Analysis
Data collection is based on physical traces, or evidence, of past
behavior.
 The selective erosion of tiles in a museum indexed by the
replacement rate was used to determine the relative
popularity of exhibits.
 The number of different fingerprints on a page was used to
gauge the readership of various advertisements in a
magazine.
 The magazines people donated to charity were used to
determine people's favorite magazines.
 Internet visitors leave traces which can be analyzed to
examine browsing and usage behavior by using cookies.

19. Relative Advantages of
Observation
 They permit measurement of actual behavior rather
than reports of intended or preferred behavior.
 There is no reporting bias, and potential bias caused
by the interviewer and the interviewing process is
eliminated or reduced.
 Certain types of data can be collected only by
observation.
 If the observed phenomenon occurs frequently or is
of short duration, observational methods may be
cheaper and faster than survey methods.

20. Relative Disadvantages of Observation
 The reasons for the observed behavior may not be determined
since little is known about the underlying motives, beliefs,
attitudes, and preferences.
 Selective perception (bias in the researcher's perception) can
bias the data.
 Observational data are often time-consuming and expensive,
and it is difficult to observe certain forms of behavior.
 In some cases, the use of observational methods may be
unethical, as in observing people without their knowledge or
consent.
It is best to view observation as a complement to survey
methods, rather than as being in competition with them.

23. Advantages and Role of Observations
 Records actual behavior, not what people say they said they did
or believe they will do.
 Recorded behavior can be compared to verbal statements or
other records, to check for the validity of their responses.
 If the researcher observes and record events, it is not necessary
to rely on the willingness and ability of respondents to report
accurately.
 The biasing effect of interviewers is either eliminated or
reduced. Data collected by observation are, thus, more
objective and generally more accurate.

24. Disadvantages of Observations
 Observation techniques do not provide insights
into what the person may be thinking, why they
performed a behavior, or what might motivate a
given behavior/comment.
 That type of information can only be obtained by
asking people directly or indirectly from written
or other sources.

25. • Time consuming.
• May bias worker performance.
• Small sample size.
• Requires skilled observer.
• Validity & reliability may be problematic.
• Not useful for jobs consisting of mostly mental tasks.
Disadvantages of Observations

26. Know How You Are Going To
Interpret Your Observations
 DESCRIPTIVE:
Requires no inference--You see something and record it.
 INFERENTIAL:
Requires making inferences about something underlying what is
observed. For example, I observe Mr. Pandey working on a
crossword puzzle. From this I infer (correctly?) that he is bored
with research.
 EVALUATIVE:
Requires making an inference and a judgment from the
observed behavior. e.g., I wonder whether people enjoy a good
challenge. “Good Challenge” is an evaluative judgment. I observe
Mr. Pandey scrunching up his puzzle and infer 1) he “failed” and
2) he hates to lose!

27. Field Notes
 When making field notes you should
include descriptive as well as contextual
data (notes can be oral or written).
 It is important to describe the setting and
the mood in detail.
 All things that may change behavior need
to be noted. Especially reflect upon your
presence.
 Do you think that you changed the
behavior noticeably?

28. Recording Data
 Recording data on blank sheets is not
recommended!
 Create data recording forms and, when
possible, use simple codes to record data
quickly.
 Consider using maps to record certain data,
such as movement.
 Agree on what to observe and record as a
team, practice, debrief, and refine. Practice
again.
