The logic of cause and effect: There are two sides to the sociological
enterprise: theoryand research. Both
are essential, and each thrives on theother.
Facts without theory are utterly
meaningless, for they lack a frameworkin which they can be understood.
8/7/2019 2- Sociological research
3/58
Theories without facts are unprovedspeculations of little practical use, because
there is no way to tell whether they arecorrect.
A theory inspires research that can be usedto verify or disprove it, and the findings ofresearch are used to confirm, reject, ormodify the theory, or even to provide thebasis of new theories.

Guesswork, intuition, and commonsense all have an important part to playin sociological research, but on theirown they cannot produce reliableevidence.
A Methodologyis a system of rules,principles, and procedures that guidesscientific investigation.
8/7/2019 2- Sociological research
5/58
Research methodologyprovides guidelinesfor collecting evidence about what takes
place, for explaining why it takes place, andfor doing so in such a way that the findingscan be checked by other researchers.
The methods of sociology can be applied onlyto questions that can be answered byreference to observable, verifiable facts.

To explain any aspect of society orsocial behavior, the sociologist mustunderstand relationship of cause andeffect.
One basic assumption of science is that
all events have causes whether theevent is ball rolling down a hill or anuclear bomb exploding.
8/7/2019 2- Sociological research
7/58
A second basic assumption is that underthe identical circumstances, the samecause will repeatedlyproduce the sameeffect.
The problem facing the sociologist is to
sort out cause from effect in thecomplexities of social life, and todetermine which of several possible
causes, is producing a particular effect.
8/7/2019 2- Sociological research
8/58
Like all scientists, the sociologist analyzescause and effect in terms of the influence of
variables on one another. A Variable is any characteristic that can
change or differ e.g. from time to time,fromplace to place, or from one individual orgroup to another.
8/7/2019 2- Sociological research

Differences in age, sex, race, and social classare variables. So are the rates of homicide,
divorce, and narcotics addiction. Causationoccurs when one variable such as
quantity of alcohol a driver consumes,influences another variable, such as thelikelihood of the driver being involved in atraffic accident.
8/7/2019 2- Sociological research
10/58
A theorysimply attempts to generalize aboutthe influence of one variable on another:
Drunken driving contributes to trafficaccidents.
An independent variable is one thatinfluences another variable in other words it
acts as a cause. A dependent variable is one that is
influenced by another variable in otherwords, it is affected.
8/7/2019 2- Sociological research
11/58
Determining cause and effect, then,involves tracing the effects of variablesupon one another. But how does itwork?
The basic method is to establish
whether there is a correlation i.e. arelationship between variables thatoccurs regularly.
8/7/2019 2- Sociological research
12/58
By analyzing the statistics, thesociologist can easily establish whetherthere is a correlation between drunkdriving and traffic accidents. In thiscase the correlation is very high.
In fact, not only are drunk driving andtraffic accidents closely associated, butthe more alcohol drivers consume, the
more likely they are to have traffic
8/7/2019 2- Sociological research
13/58
All events have causes, and the task ofscience is to trace these causes in the form of
the influence of variables upon one another. Generalizationsare statements ofprobability about relationships betweenparticular variables.
Cause and effectcan be traced byestablishing correlations betweenindependent and dependent variables.
8/7/2019 2- Sociological research
14/58
It is necessary, however, to applycontrolsto exclude the possibility thatsome variable other than the one beingstudied is influencing the relationshipunder investigation.
Logical analysis is also necessary toestablish that a relationship is causal,not spurious (merely coincidental).

Difficulties in Sociological
research Sociological research presents several
difficulties that derive from the nature of the
subject matter:1. the act of investigating behavior may
change the respondents behavior;
2. people may behave in unpredictableways;
3. the origins of social behavior areextremely complex;
8/7/2019 2- Sociological research
16/58
4. certain kinds of experiments cannot beperformed on human beings; and
5. the sociologists personal involvementwith the subjects can introduce bias intoresearch.
Some of these problems can be resolved by
combining a rigorous scientific methodologywith subjective interpretation, whichWeber called Verstehen, the German wordfor empathetic understanding.
8/7/2019 2- Sociological research
17/58
Weber asserted that sociology mustmodel itself as far as possible on thenatural sciences but that its subjectmatter, being so different, sometimesalso calls for an interpretative,
subjective approach.
8/7/2019 2- Sociological research

Basic Research Methods There are four basic methods of
sociological research:
1. Ex periments
2. Surveys
3. Observational Studies
4. Use of Existing Sources
8/7/2019 2- Sociological research
19/58
Experiments An experiment is a method for studying
the relationship between two variables
under carefully controlled conditions. Experiments can be conducted in the
laboratory or in the field.
8/7/2019 2- Sociological research
20/58
In a laboratory experiment the subjects andany necessary materials are brought into an
artificial environment that can be carefullyregulated by the researcher.
A field experiment takes place outside thelaboratory under less artificial conditions,
perhaps in a prison, hospital, or even astreet.
8/7/2019 2- Sociological research
21/58
The laboratory experiment is moreappropriate when the researcher wantsto control the situation in minute detail.
The field experiment is more suitablewhen the researcher wants to study
people in their normal settings.
8/7/2019 2- Sociological research
22/58
In the typical Experimental Method,an independent variable is introducedinto a carefully designed situation andits influence on a dependable variable isrecorded. But it requires the use of
experimentaland control groupsforvalid conclusions to be drawn.
8/7/2019 2- Sociological research
23/58
Surveys A survey is a method for systematically
obtaining standardized information about the
attitudes, behavior, or other characteristics ofa population.
Surveys are frequently used in sociologicalresearch, either simply to get facts (such as
political opinion of university students) or tofind the relationships between facts (such ashow social class or cultural backgroundinfluence studentspolitical opinion).
8/7/2019 2- Sociological research
24/58
Surveys are perhaps the form ofsociological research best known to thegeneral public, e.g. political opinionpolls.
The populationin any survey is
simply the total group ofpeople thesociologist is interested in, e.g. collegestudents, mothers with twin children, or
even the entire nation.
8/7/2019 2- Sociological research
25/58
In most cases it is necessary to survey asample, a small number of individuals drawn
from a larger population. The sample must accurately represent thepopulation in question. If it does not, thenany conclusions are valid only for the
respondents not the actual subjects of asurvey and cannot be applied to the entirepopulation.
8/7/2019 2- Sociological research
26/58
Whether a sample is representative has verylittle to do with its size. Representative ness
can be ensured by using a random sample one chosen in such a way that everymember of the population in question has thesame chance of being selected.
A survey may use questionnaires,interviews, or a combination of the two.
8/7/2019 2- Sociological research
27/58
If the questionnaire is self-administeredwithout an interview, the respondents
are asked to complete it and often toreturn it by themselves.
If the interview technique is used, the
researcher asks the questions directly. The interview may be structuredor
unstructured.
8/7/2019 2- Sociological research
28/58
In a structured interview theresearcher has a checklist of questions
and asks them in the same form andexactly the same order with eachrespondent.
It is inflexible, but it enables theresearcher to make careful tabulationsand comparisons of the answers.
8/7/2019 2- Sociological research
29/58
The unstructured interview is muchmore flexible and open-ended. The
researcher puts more general questionsto the respondents, allows them toanswer freely, and follows up on their
comments.
8/7/2019 2- Sociological research
30/58
This approach allows the researcher to getinsights that a structured interview may
overlook, but it has some disadvantages. Theanswers are often extremely difficult tocompare.
To be useful, survey questions must be put in
straightforward, unemotional language andmust be phrased so that all respondents willunderstand them in the same way.
8/7/2019 2- Sociological research
31/58
Observational Studies An observational study is an intensive
examination of a particular group,
event, or social process.
The researcher does not attempt toinfluence what happens in any way, but
aims instead at an accurate descriptionand analysis of what takes place.
8/7/2019 2- Sociological research
32/58
The analysis usually traces cause &effect relationships, but some
sociologists are content by giving aprecise account of their observations.
This information often provides rich
insights into social behavior and for thatreason alone adds to the sum ofsociological knowledge.
8/7/2019 2- Sociological research
33/58
Like the experiment, an observationalstudy can be conducted in the
laboratory or in the field.
In a laboratory observation, e.g. thesociologist mightpresent a group of
subjects with a problem in order toobserve how leaders emerge anddecisions are made.
8/7/2019 2- Sociological research
34/58
The researcher may choose to tape recordthe interaction and to watch and film it
through a two way mirror rather thaninfluencing the course of events by joiningthe group and taking notes on the spot.
In field observation the sociologist studiessomething that is happening or has happenedwithout attempting to structure the conditionsof observation.
8/7/2019 2- Sociological research
35/58
Most observational studies take place inthe field.
The most common form of fieldobservation is the case study acomplete and detailed record of anevent, group, or social process.
Some case studies deal with events thathave already taken place.
8/7/2019 2- Sociological research
36/58
The sociologist reconstructs theseevents through extensive interviews
with the participants and by referring toother sources of data, ranging frompolice records to newspaper files.
8/7/2019 2- Sociological research
37/58
This method is often used for theanalysis of infrequent, temporary
events such as riots.
Other case studies are conducted at thetime the action is taking place.
These eyewitness studies are a richsource of sociological information andinsights.
8/7/2019 2- Sociological research
38/58
The sociologist in a case study maychoose to be either a detachedor a
participantobserver. Detached observationis a method in
which the researcher remains as aloofas possible, and the subjects may noteven know they are being studied.
8/7/2019 2- Sociological research
39/58
Participant observationis a methodin which the researcher becomes
directly involved in the social behaviorunder study.
Sometimes the P.O. makes it clear to
the group that he/she is a sociologist;at other times the sociologistpretendsto be an ordinary member of the group.
8/7/2019 2- Sociological research
40/58
The latter approach has the advantagethatpeople will behave in more typical
ways if they do not know they are beingobserved, and it also enables thesociologist to gain access to groups
such as some religious sects thatwould not normally allow them to bestudied.
8/7/2019 2- Sociological research
41/58
Observational studies of this kind placea heavy obligation on the sociologist.
The identities of informants must beprotected.
Systematic notes must be kept each
day while memory is fresh. The observer must be careful not to influence
the behavior he/she is studying.
8/7/2019 2- Sociological research
42/58
The assumption behind participantobservation is that some things can be
fully understood only by intimateexperience of them, but the methodrelies heavily on the skills andsubjective interpretations of the
observer.
8/7/2019 2- Sociological research
43/58
Observational studies have theadvantage that they come to grips with
real-life situations, thereby offeringinsights those years of experimentingand surveying might overlook.
8/7/2019 2- Sociological research
44/58
It has the disadvantage, however, ofsacrificing scientific precision to some extent.
The observer may misinterpret events, mayignore things that are relevant and focus onthings that are trivial.
Another disadvantage is that the case studied
may have been exceptional, so the findings ofa single observational study cannot begeneralized to all apparently similar cases.
8/7/2019 2- Sociological research
45/58
Use ofExisting Sources Sometimes the sociologist does not
have to generate new information
through experiments, surveys, orobservational studies. The relevant datamay already exist and may merely have
to be collected and analyzed.
8/7/2019 2- Sociological research
46/58
A great deal of useful information isavailable in published or unpublished
form in the form of government record,newsreels, diaries, letters, works of art& literature, historical records, or the
research findings of other socialscientists.
8/7/2019 2- Sociological research
47/58
Another important source of existinginformation is the accumulated body of
sociological research. Information from this source can be collected
and reinterpreted;
Findings ofpreviously isolated reports can berelated to one another in new and revealingways;
8/7/2019 2- Sociological research
48/58
The data that one sociologist collectedto answer one question can sometimes
be used by another sociologist toanswer a different question.

A Research Model1 Define the problem: Choose a suitable
topic for a research project. The generalarea selected will usually be one in whichthe sociologist takes a personal interest.
2 Review the literature: The existingresearch on the problem must be trackeddown and reviewed.
8/7/2019 2- Sociological research
50/58
Knowledge of the relevant literature isessential. Itprovides background
information, suggests theoreticalapproaches, indicates which areas ofthe topic have already been covered
and saves the sociologist the labor &embarrassment of duplicating researchthat has already been done.
8/7/2019 2- Sociological research

3. Formulate a hypothesis: Theresearch problem must be stated in
such away that it can actually betested. This is achieved by formulatinga hypothesis, a tentative statementthatpredicts a relationship between
variables.
8/7/2019 2- Sociological research
52/58
For each idea in the hypothesis, the researchermust create an operational definition one thatstates a concept, for the purposes of research, in
terms that can be measured.4 Choose a research design: Select one ormore research methods: experiment, survey,observational study, or use of existing sources.
5Collect the data: Collect and recordinformation in accordance with the researchdesign.
8/7/2019 2- Sociological research
53/58
6 . Analyze the Results: Arrange theinformation in orderly form and
interpret the findings. Confirm,reject,ormodify the hypothesis.
7 .Draw a Conclusion: Discuss thesignificance of the findings,relating
them to existing theory andresearchanddefiningproblemsforfutureresearch.

Research Ethics The American Sociological Association has
developed a code of ethics for researchers,
which specifies that the researchers shouldmaintain:
a) objectivity and integrity;
b) respect the privacy & dignity of subjects;
8/7/2019 2- Sociological research
55/58
c)protect subjects from harm;
d)preserve confidentiality ofpersonaldata collected during research; and
e) acknowledge sources of assistance,collaboration, and funding;
8/7/2019 2- Sociological research
56/58
Ethical dilemma There are five basic types of dilemma:
Harm to participants: Research should not
risk physical, psychological, or moral harm tothe participants.
Invasion ofprivacy: Any research intopeoples lives risks invading their privacy. Theproblem arises particularly when thesociologist uses unobtrusive measures i.e.ways of studying people without their consent
8/7/2019 2- Sociological research
57/58
Informed consent: A basic respectforonessubjectssuggeststhatthe
researchershould notonly make themaware thatthey are being studied butshould alsoobtaintheirpermission.
