Observational Field Research
This web page is designed as an introduction to the basic issues and design
options in observational research within natural settings. Observational
research techniques solely involve the researcher or researchers making
observations. There are many positive aspects of the observational
research approach. Namely, observations are usually flexible and do not
necessarily need to be structured around a hypothesis (remember a
hypothesis is a statement about what you expect to observe). For instance,
before undertaking more structured research a researcher may conduct
observations in order to form a research question. This is called
descriptive research. In terms of validity, observational research
findings are considered to be strong. Trochim states that validity is the
best available approximation to the truth of a given proposition,
inference, or conclusion. Observational research findings are considered
strong in validity because the researcher is able to collect a depth of
information about a particular behavior. However, there are negative
aspects. There are problems with reliability and generalizability.
Reliability refers the extent that observations can be replicated. Seeing
behaviors occur over and over again may be a time consuming task.
Generalizability, or external validity, is described by Trochim as the
extent that the study's findings would also be true for other people, in
other places, and at other times. In observational research, findings may
only reflect a unique population and therefore cannot be generalized to
others. There are also problems with researcher bias. Often it is assumed
that the researcher may "see what they want to see." Bias, however, can
often be overcome with training or electronically recording observations.
Hence, overall, observations are a valuable tool for researchers.
First this Web Page will discuss the appropriate situations to use
observational field research. Second, the various types of observations
research methods are explained. Finally, observational variables are
discussed. This page's emphasis is on the collection rather the analysis
of data.
After reading this web page, you should be able to
- Understand the advantages and disadvantages of observational research
compared to other research methods.
- Understand the strengths and weaknesses in the validity of
observational research findings.
- Know what Direct Observation is and some of the main concerns of using
this method.
- Know what Continuos Monitoring is and what types of research it is
appropriate for.
- Understand Time Allocation research and why you would want to use it.
- Know why unobtrusive research is a sticky proposition.
- Understand the validity issues when discussing unobtrusive observation.
- Know what to do in a behavior trace study.
- Consider when to conduct a disguised field experiment.
- Know the observational variables.
Should you or shouldn't you collect your data through observation?
Questions to consider:
- Is the topic sensitive?
- Are people uncomfortable or unwilling to answer questions about a
particular subject? For instance, many people are uncomfortable when
asked about prejudice. Self-reports of prejudice often bring biased
answers. Instead, a researcher may choose to observe black and white
students interactions. In this case, observations are more likely to bring
about more accurate data. Thus, sensitive social issues are better suited
for observational research.
- Can you observe the Phenomena?
- You must be able to observe what is relevant to your study. Let's face
it, you could observe and observe but if you never see what your studying
your wasting your time. You can't see attitudes. Although you can observe
behaviors and make inferences about attitudes. Also, you can't be
everywhere. There are certain things you can't observe. For example,
questions regarding sexual behavior are better left to a survey.
- Do you have a lot of time?
- Many people don't realize that observational research may be time
consuming. In order to obtain reliability, behaviors must be observed
several times. In addition, there is also a concern that the observer's
presence may change the behaviors being observed. As time goes on,
however, the subjects are more likely to grow accustomed to your presence
and act normally. It is in the researchers best interest to observe for a
long period of time.
- Are you not sure what your looking for?
- That's okay! Known as descriptive research, observations are a great
way to start a research project. Let's say you are interested in male
and female behavior in bars. You have no idea what theory to use or what
behavior you are interested in looking for. So, you watch, and, wow, you
see something. Like the amount of touching is related to alcohol
consumption. So you run to the library, gather your research, and maybe
decide to do more observations or supplement your study with surveys.
Then, these observations turn into a theory once they are replicated (well,
it's not quite that simple). So you see, observations are a good place to
start.
Types of Observations
Okay, so you've decided that you think observational research is for
you. Now you only have to pick which kind of observation to do.
- Unobtrusive Observation:
Unobtrusive measures involves any method for studying behavior where
individuals do NOT know they are being observed (don't you hate to think
that this could have happened to you!). Here, there is not the concern
that the observer may change the subject's behavior. When conducting
unobtrusive observations, issues of validity need to be considered.
Numerous observations of a representative sample need to take place in
order to generalize the findings. This is especially difficult when
looking at a particular group. Many groups posses unique characteristics
which make them interesting studies. Hence, often such findings are not
strong in external validity. Also, replication is difficult when using
non-conventional measures (non-conventional meaning unobtrusive
observation). Observations of a very specific behaviors are difficult to
replicate in studies especially if the researcher is a group participant
(we'll talk more about this later). The main problem with unobtrusive
measures, however, is ethical. Issues involving informed consent and
invasion of privacy are paramount here. An institutional review board may
frown upon your study if it is not really necessary for you not to inform
your subjects.
Here is a description of two types of unobtrusive research measures you
may decide to undertake in the field:
- Behavior Trace studies:
Behavior trace studies involve findings things people leave behind and
interpreting what they mean. This can be anything to vandalism to garbage.
The University of Arizona Garbage Project one of the most well-known trace
studies. Anthropologists and students dug through household garbage to
find out about such things as food preferences, waste behavior, and alcohol
consumption. Again, remember, that in unobtrusive research individuals do
not know they are being studied. How would you feel about someone going
through your garbage? Surprisingly Tucson residents supported the research
as long as their identities were kept confidential. As you might imagine,
trace studies may yield enormous data.
- Disguised Field Observations:
Okay, this gets a little sticky. In Disguised field analysis the
researcher pretends to join or actually is a member of a group and records
data about that group. The group does not know they are being observed for
research purposes. Here, the observer may take on a number of roles.
First, the observer may decide to become a complete-participant in which
they are studying something they are already a member of. For instance, if
you are a member of a sorority and study female conflict within sororities
you would be considered a complete-participant observer. On the other hand
you may decide to only participate casually in the group while collecting
observations. In this case, any contact with group members is by
acquaintance only. Here you would be considered an observer-participant.
Finally, if you develop an identity with the group members but do not
engage in important group activities consider yourself a
participant-observer. An example would be joining a cult but not
participating in any of their important rituals (such as sacraficing
animals). You are however, considered a member of the cult and trusted by
all of the members. Ethically, participant-observers have the most
problems. Certainly there are degrees of deception at work. The
sensitivity of the topic and the degree of confidentiality are important
issues to consider. Watching classmates struggle with test-anxiety is a
lot different than joining Alcoholics Anonymous. In all, disguised field
experiments are likely to yield reliable data but the ethical dilemmas are
a trade-off.
An Interesting Side Note:
The protection of human rights from unethical research practices was
heightened as a consequence of the Nazi regime in Germany. The Nuremberg
Code was adopted following the trials of the twenty-three Nazi physicians
convicted of crimes against humanity. This Code provided a statement
concerning the rights of human participants to be informed and freely
choose to participate in research. The Nuremberg Code has since influenced
policies of ethical research practices in several countries.

Observational Variables
Before you start on a research project make sure you how you are going
to interpret your observations.
- Descriptive:
Descriptive observational variables require no inference making on the part
of the researcher. You see something and write it down.
- Inferential:
Inferential observational variables require the researcher to make
inferences about what is observed and the underlying emotion. For example,
you may observe a girl banging on her keyboard. From this observation you
may assume (correctly) that she is frustrated with the computer.
- Evaluative:
Evaluative observational variables require the researcher to make an
inference and a judgment from the behavior. For example, you may question
whether computers and humans have a positive relationship. "Positive" is
an evaluative judgment. You observe the girl banging on her keyboard and
conclude that humans and computers do not have a positive relationship (you
know you must replicate these findings!).
When writing field notes the researcher should include descriptive as well
as inferential data. It is important to describe the setting and the mood
in a detailed manner. All such things that may change behavior need to be
noted. Especially reflect upon your presence. Do you think that you
changed the behavior noticeably?
Okay, so this is a lot to remember. Go back up to the check-list of
"things you should be able to..." and ask yourself some questions.
Remember, observations are a great way to start and add to a research
project.
Good luck observing!
