Field observation is useful for collecting data and
for generating hypotheses and theories. Like all qualitative techniques, it is
concerned more with description and explanation than with measurement and quantification. Below figure shows that field observations
are classified along two major dimensions: (1) the degree to which the
researcher participates in the behaviour under observation and (2) the degree
to which the observation is concealed.
Dimension of Field Observation
Dimension of Field Observation
Quadrant 1 in the
above figure represents overt observation. In this situation, the researcher is
identified when the study begins, and those under observation are aware that they
are being studied. Furthermore, the researcher’s role is only to observe,
refraining from participation in the process under observation.
Quadrant 2
represents overt participation. In this arrangement, those being observed also
know the researcher, but unlike the situation represented in Quadrant 1, the
researcher goes beyond the observer role and becomes a participant in the situation.
Quadrant 3
represents the situation where the researcher’s role is limited to that of
observer, but those under observation are not aware they are being studied.
Quadrant 4
represents a study in which the researcher participates in the process under investigation
but is not identified as a researcher.
Field Observation Techniques
There are at least six stages in a typical
field observation study: choosing the research site, gaining access, sampling,
collecting data, analysing data, and exiting.
Choosing
the Research Site: The
nature of the research question or area of inquiry usually suggests behaviour
or a phenomenon of interest. Once it is identified, the next step is to select
a setting where the behaviour or phenomenon occurs with sufficient frequency to
make observation worthwhile. The settings also should fit the recording forms
and instruments the observer plans to use. For example, video recording usually
requires adequate lighting for the camera to operate.
Possible research venues can be identified from
personal experience, from talking with other researchers, from interviews with
people who frequent the site, or from newspaper and magazine stories.
Qualitative researchers should avoid choosing
sites where they are well known or have some involvement in the area. Studying one’s
own workplace, for example, is difficult because the researcher’s preconceptions
may preclude observations that are more objective. Furthermore, at a site where
the researcher is a familiar figure, other individuals may find it difficult to
relate to a colleague or friend in the role of researcher.
Gaining Access.
Once the site is selected, the next
step is to establish contact. Gaining access to settings depends on two
factors:
(1) How public the setting is; and
(2)
The willingness of the subjects in the setting to be observed.
The easiest setting to enter is one that is open to the public. The most
difficult setting to enter is one where entry is restricted because participants
have good reason to keep their activities confidential. Gaining permission to
conduct field observation research requires persistence and public relations
skills.
After the contact is made, rapport must be established with the
subject(s). Bogdan and
Taylor (1998) suggests the following techniques for building rapport:
Establish common interests with the
participants;
Start relationships slowly;
If appropriate, participate in common events
and activities; and
Do not disrupt participant’s normal routines.
Sampling. Most
field observations use purposive sampling, where observers draw on their knowledge
of the subject(s) under study and sample only from the relevant behaviours or
events. Sometimes previous experience and study of the activity in question suggest
what needs to be examined.
Here are some sampling strategies that might
be used (Lindlof, 1995):
• Maximum variation sampling: Settings,
activities, events, and informants are chosen purposefully to yield as many
different and varied situations as possible.
• Snowball sampling: A participant
refers the researcher to another person who can provide information. This person,
in turn, mentions another, and so forth.
• Typical case sampling: In contrast
to the maximum variation technique, the researcher chooses cases that seem to be
most representative of the topic under study.
Collecting Data: The
traditional data collection tools—notebook and pencil, a camera can record more
information than an observer. Video cameras and video recordings have become
more portable and easier to use. In addition to first hand observation, three
other data collection techniques are available to field researchers:
diary keeping,
unobtrusive measures, and
document analysis.
With the first
technique, an investigator routinely supplements his or her field notes by
keeping a research diary. This diary consists of personal feelings, sentiments,
occasional reflections, and other private thoughts about the research process
itself; the writings augment and help interpret the raw data contained in the
field notes. Moreover, the researcher may ask the individuals under study to
keep a diary for a specified length of time.
A second data collection
technique available to the field researcher is unobtrusive measurement. This
technique helps overcome the problem of reactivity by searching out naturally
occurring phenomena relevant to the research task. The people who provide data
through unobtrusive measurement are unaware that they are providing information
for a research project. Covert observation, as previously mentioned, is
obviously a technique of this type.
Finally, existing
documents may represent a fertile source of data for the qualitative
researcher. In general terms, two varieties of documents are available for
analysis:
Public and
Private.
Public documents include police reports,
newspaper stories, transcripts of TV shows, data archives, and so on. Other items
may be less recognizable as public documents, however; messages on Internet bulletin
boards, blogs, websites, company newsletters, tombstones, posters, graffiti,
and bumper stickers can all fit into this category.
Private documents, on the other hand, include
personal letters, diaries, memos, faxes, emails, home movies and videos,
telephone logs, appointment books, reports, and so on
Analysing Data
Concerning the specific technique of field
observation, data analysis primarily consists of filing the information and analysing
its content. Constructing a filing system is an important step in observation. The
purpose of the filing system is to arrange raw field data in an orderly format that
is amenable to systematic retrieval later. The overall goal of data analysis in
field observation is to arrive at a general understanding of the phenomenon
under study. In this regard, the observer has the advantage of flexibility.
Exiting
A researcher acting as a participant must
have a plan for leaving the setting or the group under study. Of course, if
everyone knows the participant, exiting is not a problem. Exiting from a
setting that participants regularly enter and leave is also not a problem.
Exiting can be difficult, however, when participation is covert. In some
instances, the group may have become dependent on the researcher in some way,
and the departure may have a negative effect on the group as a whole. In other
cases, the sudden revelation that a group has been infiltrated or duped by an
outsider might be unpleasant or distressing to some. The researcher has an
ethical obligation to do everything possible to prevent psychological,
emotional, or physical injury to those being studied. Consequently, leaving the
scene must be handled with diplomacy and tact.
Advantages of Field Observations
Field observation often helps the researcher
define basic background information necessary to frame a hypothesis and to isolate
independent and dependent variables.
Field observation may also provide access to
groups that would otherwise be difficult to observe or examine.
Field observation is usually inexpensive. In
most cases, it requires only writing materials or a small audio or video
recorder.
Field observation is that the study takes
place in the natural setting of the activity being observed and thus can
provide data rich in detail and subtlety
Disadvantages of Field Observations
Validation is difficult partly because the
representativeness of the observations made is potentially questionable and
partly because of problems in sampling.
Since field observation relies heavily on a
researcher’s perceptions and judgments and on preconceived notions about the
material under study, experimenter bias may favour specific preconceptions of
results, while observations to the contrary are ignored or distorted.
Finally, field observations suffer from the problem
of reactivity. The very process of being observed may influence the behaviour under
study.
