(1) Observation Method
This is the most commonly used method of data collection especially instudies relating to behavioural sciences.
Accurate watching and noting of phenomenon as they occur in nature
with regard to cause and effect or mutual relation is called observation
method of data collection.

Characteristics of Observation Method
Direct Method: In observation method data collected through direct contactwith phenomenon under study. In this method sensory organs particularly
eye, ear, voices are used.
Source of primary data:This is a classical method for collection of primary
data.
Requires in-depth study:Here the observer goes to the field and make thestudy of the phenomenon in an indepth fashion to acquire data.
Collection follows observation:In this method the investigator first of all
observes the things and then collects the data.
Selective and purposeful collection:The observations are made with definite
purpose. Collection of materials is done according to a particular purpose.

Merits of Observation Method
Common method: The method of observation is common to all thedisciplines of research.
Simplicity: This method is very simple to use.
Realistic: Since observation is based on actual and first hand experience, its
data are more realistic than the data of those techniques which used
indirect and secondary source of information.
Verification: For verification of hypothesis, we have to depend on
observation. Therefore, it can be said that the problem presents itself and
resolves itself through observation.

Limitation of Observation Method
Some observations cannot be treated as objects of observation: Thereare certain events which may not occur at a definite time and cannotbe noticed for observation purpose. For example, it is not possible toobserve emotions and sentimental factors, likes and dislikes etc.
Slowness of investigation: The slowness of observation methods leadto disheartening, disinterest among both observer and observed.
Expensive Methodology: Being a long drawn process, the technique ofobservation is expensive.

(2) Personal Interview Method
Under this method of collecting data there is a face to face contactwith the persons from whom the information is to be obtained knownas informants.
The interviewer asks them questions regarding the survey and gathersthe desired information.
For example, if a person wants to collect data about the workingconditions of the workers of Hindustan Unilever Ltd., Mumbai. Then hehas to go to the Mumbai plant and ask question to the workers towhom he has chosen as sample.

Types of Interviews
1. Classification Formal interview: In this type of interview, the interviewer presents
a set of well defined questions and notes down answers ofinformants in accordance with prescribed rules.
Informal interview: In contrast with the formal interview theinterviewer has full freedom to make suitable alternations in the
questions to suit a particular situation in formal interviews..2. Classification according to the number: Another classification ofinterview is according to the number of persons taking part in theresearch process. Following are its main types:
Personal interview: In personal interview single interviewer isinterviewed. The personal interview helps to establish close personal
contacts between the interviewer and the interviewee and as a resultdetailed information can be obtained.
Group interviews: Here two or more persons are interviewed at atime. It is suitable to gather information in a group discussion andcross check can be possible.

3. Classification according to the period of contact:The different types of problems
require different amount of time for contact with the respondents.
Short-contact interview: For filling-up schedules etc., a single sitting of small
duration is sufficient.
Prolonged Contact of interviews: In case of studies where case history method of
research is applied, the interview requires for a long duration to get accurate
information on the respondents.
4. Other Classification:
a. Paired Interview
b. Informal, Conversational Interview
c. Closed, Fixed Response Interview
d. Standardized, Open-ended Interview
e. Business Interview

Merits of the Method
Interviews are ideal for investigating personal, sensitive, or confidential
information which is unsuitable to cover in a group format.
This is also the best method for advertising pre-testing, where the
researcher is seeking individual interpretations and responses.
Demerits of the Method
A skilled interviewer can overcome this to a large degree, through the
establishment of good rapport and trust.

(3) Questionnaire Method
A questionnaire is a tool or device for securing answers to the set ofquestions by the respondents who fills in the form of questionnaire
himself.
It is systematic compilation of questions that are submitted to a
sample of population from which information is desired.
The questions in a questionnaire are generally arranged in a sequencedepending on the nature of study and are capable of reply.

Schedule Method
The name schedule is usually applied to a performa containing a set ofquestions which are asked and filled by an interviewer in a face to face
situation with a respondent.

Types of Schedules
Observation Schedule:Those schedules that are used in observationresearch is called as observation schedule. In these schedulesobserver records the activities and responses of a worker or a groupunder specific conditions.
Rating Schedules:In the field of business guidance, psychologicalresearch, and social research, the rating schedules are used to assessthe attributes, opinions, preferences and other qualitative elements.
Document Schedule: The schedules of this type are used to obtaindata regarding written evidence and case histories from diary, casehistories of the companies or Government records, etc.
Interview Schedule:In an interview schedule an interviewer presents
the questions of the schedule to interviewee and records theirresponses.

Case Study Method
One of the important and frequently used methods in the area ofmanagement and social sciences for the purpose of investigation is the case
study method.
It is a frequently used method of studyinga person, a group of persons or
community.
Characteristics of Case Study Method
Comprehensive study of a unit: All aspects are studied deeply and
thoroughly.
It deals with both what and why aspect of the problem identified
It makes the individual unit into integrated whole.
In such a case, individual, family, institution or group is considered as a
unified whole.

Merits of Case Study
It helps in formulating hypothesis, Possibility of intensive study
No need of using sampling techniques
Deeply narrates the subjective aspects of the problem
Demerits of the Method
Comparison is not possible
No method of checking

Kinds of Social Survey
Regular orAd hocSurvey: Census by Government of India & economicsurvey by RBI, etc., are regular surveys.
Official and Non-official Survey: Survey by Government is official. Survey by
individual, organizations, municipalities, corporations and other
autonomous private bodies are non-official.
Direct or Indirect Survey: In those studies where primary data are collectedfrom the field is the nature of direct study whereas study that uses
secondary data are indirect.

Primary or Secondary Survey: In the primary survey, researcher involveshimself/herself in the field while in secondary one he/she depends on thework of other researcher.
Personal or Impersonal Survey: Information collected from the personhimself/herself is personal and the information collected from other one onbehalf of the person is impersonal survey.
First or Repetitive Survey: When survey carried out in a particular area or on aparticular subject for the first time is called first or initial survey whereassurvey carried out again and again which is popularly called as repute.

Demerits of the Method
The method needs heavy fund. There is no uniformity in the collection of data as is based on the
individual motive.
The method needs more time for result.
Unexpected difficulties may emerge while at work

Field Study
Field study becomes a scientific tool for the researcher to the extent that itserves as a formulated research purpose, planned systematically, related to
move general theoretical analysis, recorded systematically and is subject to
checks and controls on validity and reliability.

Why Field Study
Explore the given area of Subject matter
Gain Insight into Subject Matter
Provide a base for development of hypothesis
Types of Study
Descriptive
Exploratory
What Should be Studied?
In highly-structured studies, the well formulated research problem or
hypotheses clearly point to what data will be most relevant.
But in exploratory studies which is mostly used in case of unstructured
observation, the researcher doesnt know in advance about the different
aspects of the situation will present.

How the information can be Recorded?
Two major Decisions
i. When notes be taken?
ii. How the notes be kept?
Researcher should be clear in his or her mind by pointing out who are
the participants, how many they are and how they are related to one
other.
He should understand the existing environment under investigation.
The climate conditions, respondents; appearance, the kind of behaviorexpected, and the social character, etc. should be well scanned by the
researcher before going for field study.
The purpose which he has brought the subject participants together, the
nature and the purpose and how the goals of participants are related
etc.. Should be pronounced clearly.
The researcher must understand what participants are doing, how, with
whom and with what they are involved with.
In case of participant observer, he/she should attach emotionally with
the respondents.
-

Merits of the Method
The investigator becomes a member of the community being observed by him.Since the community does not know the purpose of the research, it makes the
researcher to gather useful data as per his requirements.
The researcher involves himself/herself in the field, he/she becomes able to gather
deep knowledge.
In this method opinion of the respondents from the field are interpreted accuratelysince there is no question of biasness or pressure emerges to suppress the truth.

27/33
Demerits of the Method
If the investigator has narrowed in the range of experience, this methodmay not be an appropriate to choose as an ideal method for collecting
primary data.
Non-participant study makes the process of field study difficult.
It is difficult to overcome the problems which may surface in the field.
It is time consuming and needs more funds.

Field Experiment
Festinger, was of the opinion that, the experiment method experiments theeffect on a dependent variable due to the manipulation of an independent
variable.
Experiment studies the control over the subject of study and manipulation of
the independent variable to study the effect on dependent variable.

Types of Field Experiments
Trial and Error Experiment:This is an earliest form of experiment method.Under this method, the researcher does not prepare a structured plan of
study.
Controlled Observation Study:This includes observation of the phenomena
under controlled conditions and therefore, comes closer to laboratory type of
experiment.

Natural Experiment:Natural experiment is otherwise known as the fieldexperiment since the experiment is conducted in the field in a natural setting.
Ex-post-facto Technique:This technique is generally used to study the varying
influence of two identical factors.
Laboratory Experiment: A laboratory experiment has been defined by
Festinger, as one in which the investigator creates an artificial situation withthe exact conditions that prevail in the field in which he/she has certain
controls on some variables and manipulates others.

Rapid Rural Appraisal (RRA)& Participatory Rural Appraisal (PRA)
RRA emerged in the 1970s as a more efficient and cost-effective way oflearning by outsiders, particularly about agricultural systems, that was
possible by large-scale social surveys or brief rural visits by urban
professionals.
