This document discusses various tools and methods for data collection. It defines data collection as the process of gathering information from relevant sources to answer research questions and test hypotheses. There are two main sources of data - primary sources where data is directly collected, and secondary sources where data is collected by someone else. Common tools for collecting data include interviews, questionnaires, observations, and various bio-physiological methods. The appropriate method depends on factors like the type of research, sample size, and available resources. Interview and questionnaire-based tools are described in more detail.
Questionnaires, interviews, observation, and existing data are common methods for collecting data in research. Questionnaires involve paper or online surveys to collect self-reported information from participants. Interviews are conducted face-to-face, by phone, or online and allow researchers to ask participants questions and get more in-depth responses than questionnaires. Observation research involves watching and recording behaviors directly. Existing data sources include medical records, organizational records, journals, and other documents that contain relevant pre-collected information.
This document discusses various methods of primary and secondary data collection. It describes key advantages and disadvantages of primary data collection methods like surveys and interviews which involve collecting data directly from subjects.

1. Fieldwork involves learning activities conducted outside the classroom to gather new information. Various methods are used to collect primary and secondary data, including observation, questionnaires, interviews, records analysis, sampling, and measurement.
2. The key steps in fieldwork include pre-field preparation, pilot study, data collection, and follow-up. Data collection methods have advantages and disadvantages that researchers must consider for their specific studies.
3. Presenting findings involves organizing, analyzing, and communicating the data through written reports, displays, presentations and other methods. Careful planning is needed to address challenges that may arise during fieldwork.
Interviews involve collecting data through talking to respondents and recording their responses, which can be structured or unstructured and conducted face-to-face or by telephone. In-depth interviews delve below surface responses to gain insights into meanings and complex attitudes, but are time consuming and difficult to analyze. Sample sizes for in-depth interviews are small to provide rich insights rather than statistics, and the interview process involves informing respondents, asking open-ended questions, and recording responses.

2. TYPES OF DATA
• PRIMARY DATA
• Are those which are collected a fresh and for the first time and thus
happen to be original in character and known as Primary data.
• SECONDARY DATA
• Are those which have been collected by someone else and which
have already been passed through the statistical process are known
as Secondary data.
3. COLLECTION OF PRIMARY DATA
• There are several methods of collecting primary data, particularly in
surveys and descriptive researches.
• In descriptive research, we obtain primary data either through
observation or through direct communication with respondents in
one form or another or through personal interviews.
4. Methods of data Collecting Primary Data
• OBSERVATION METHOD :
• Observation method is a method under which data from the field is collected
with the help of observation by the observer or by personally going to the field.
• ADVANTAGES
• Subjective bias eliminated
• Researcher gets Current information
• Independent to respondent’s variable
• DISADVANTAGES
• It is expensive method
• Time consuming
• Limited information
• Unforeseen factors may interfere with observational task
• Respondents opinion can not be recorded on certain subject
5. TYPES OF OBSERVATION
• Structured Observation
• When observation is done by characterizing style of recording the observed
information, standardized conditions of observation , definition of the units to
be observed , selection of pertinent data of observation then it is structured
observation
• Unstructured Observation
• When observation is done without any thought before observation then it is
unstructured observation
6. TYPES OF OBSERVATION
• Participant & Non Participant Observation
• When the Observer is member of the group which he is observing
then it is Participant Observation. In participant observation
Researcher can record natural behavior of group , Researcher can
verify the truth of statements given by informants in the context of
questionnaire , Difficult to collect information can obtain through this
method but in this researcher may loose objectivity of research due
emotional feelings. Prob. of control in observation isn’t solved.
• Non Participant Observation• When observer is observing people
without giving any information to them then it is non participant
observation
7. TYPES OF OBSERVATION
• Controlled & Uncontrolled Observation
• When the observation takes place in natural condition i.e.
uncontrolled observation. It is done to get spontaneous picture of life
and persons
• When observation takes place according to definite pre arranged
plans , with experimental procedure then it is controlled observation
generally done in laboratory under controlled condition.
8. INTERVIEW METHOD
• This method of collecting data involves presentation or oral-verbal
stimuli and reply in terms of oral-verbal responses.
• Interview Method This is Oral Verbal communication . Where
interviewer asks questions( which are aimed to get information
required for study ) to respondent
• There are different type of interviews:
• PERSONAL INTERVIEWS : The interviewer asks questions generally in a
face to face contact to the other person or persons.
9. Types of Personal Interview
• Structured Interview
• Predetermined questions
• Standardized techniques of recorded
• Interviewer follows rigid procedure
• Time required for such interview is less than non structured manner interview
• Not necessary of skill or specific knowledge
• Analysis of data becomes easier
• Unstructured Interview
• No Predetermined questions
• No Standardized techniques
• Interviewer has freedom to ask, omit, add any questions
• Ask questions without following sequence
• Deep knowledge & skill required
• Analysis of data is difficult prescribed manner
10. Merits of Personal Interview
• Information at greater depth
• Flexibility of restructuring the Questionnaire
• Interviewer by his skill can over come resistance
• Non Response generally low
• Samples can controlled more effectively
• Personal information can be obtained
• Interviewer can collect supplementary information about
respondent’s personal characteristics and environment which has
value in interpreting results
11. De Merits Of Interview
• Expensive method
• Respondent may give bias information
• Some Executive people are not approachable so data collected may
be inadequate
• Takes more time when samples are more
• Systematic errors may be occurred
• Supervisors has to do complex work of selecting ,training and
supervising the field staff.
13. TELEPHONIC INTERVIEWS -MERITS
• Flexible compare to mailing method
• Faster than other methods
• Cheaper than personal interview method
• Call-backs are simple and economical also
• High response than mailing method.
• When it is not possible to contact the respondent directly, then interview is
conducted through – Telephone
• Replies can be recorded without embarrassment to respondents
• Interviewer can explain requirements more easily
• No field staff is required
• Wider distribution of sample is possible
14. TELEPHONIC INTERVIEWS -DEMERITS
• Little time is given to respondents
• Survey is restricted to respondents who have telephones
• Not suitable for intensive survey where comprehensive answers are
required
• Bias information may be more
• Very difficult to make questionnaire because it should short and to
the point
15. Other Types
• Focused interviews : attention is focused on the given experience of the
respondent and its possible effects.
• Clinical interviews : concerned with broad underlying feelings or motivations or
with the course of individual’s life experience, rather than with the effects of the
specific experience, as in the case of focused interview.
• Group interviews : a group of 6 to 8 individuals is interviewed.
• Qualitative and quantitative interviews : divided on the basis of subject matter
i.e. whether qualitative or quantitative.
• Individual interviews : interviewer meets a single person and interviews him.
• Selection interviews : done for the selection of people for certain jobs.
• Depth interviews : it deliberately aims to elicit unconscious as well as other types
of material relating especially to personality dynamics and motivations.
16. QUESTIONNAIRE METHOD
• This method of data collection is quite popular, particularly in case of
big enquiries. The questionnaire is mailed to respondents who are
expected to read and understand the questions and write down the
reply in the space meant for the purpose in the questionnaire itself.
The respondents have to answer the questions on their own.
• Questionnaire Method Questionnaire is sent to persons with request
to answer the questions and return the questionnaire Questions are
printed in definite order , mailed to samples who are expected to
read that questions understand the questions and write the answers
in provided space .
17. Merits of Questionnaire
• Low cost even the geographical area is large to cover
• Answers are in respondents word so free from bias
• Adequate time to think for answers
• Non approachable respondents may be conveniently contacted
• Large samples can be used so results are more reliable
18. Demerits of Questionnaire
• Low rate of return of duly filled questionnaire
• Can be used when respondent is educated and co operative
• It is inflexible
• Omission of some questions
• Difficult to know the expected respondent have filled the form or it is
filled by some one else
• Slowest method of data collection
19. Main aspects of a Questionnaire
1. General Form
• Structured questionnaire – All questions and answers are specified
and comments in the respondents own words are held to the
minimum.
• Unstructured questionnaire- Interviewer is provided with general
guide on the type pf information to be collected. He can form his own
questions.
• Answers are taken down in respondents own words, at time recorded
on tape.
20. Main aspects of a Questionnaire
2. Question sequence
• Question sequence should be clear and smoothly moving (relation of
one question to another should readily apparent
• First few questions are important for creating interest in respondents
mind
• Question which gives stress on memory or of a personal character
and wealth should be avoided as opening questions
• Easier question should be at the start of the questionnaire
• General to specific questions should be the sequence of questions
21. Main aspects of a Questionnaire
3. Question formation and wording
• Question should easily understood Question should be simple and
concrete.
• Closed questions are easy to handle but this is like fixing the answers
in people’s mouth. So depending upon problem for which survey is
going on both close ended and open ended question may be asked in
Questionnaire.
• Words having ambiguous meaning should be avoided
• Catch words, words with emotional connotations , danger words
should be avoided.
22. Essentials of Good Questionnaire
• Good Questionnaire Should Short & simple Questions
• Should arranged in logical sequence (From Easy to difficult one)
• Technical terms should avoided
• Some control questions which indicate reliability of the respondent ( To
Know consumption first expenditure and then weight or qty of that
material)
• Questions affecting the sentiments of the respondents should avoided
• Adequate space for answers should be provided in questionnaire
• Provision for uncertainty (do not know, No preference)
• Directions regarding the filling of questionnaire should be given
