Primary Data ? Raw data or primary data is a term for data collected at source. This type of information is obtained directly from first hand sources by means of surveys, observations and experimentation and not subjected to any processing or manipulation and also called primary data.
Secondary Data ? It refers to the data collected by someone other than the user i.e. the data is already available and analysed by someone else. Common sources of secondary data include various published or unpublished data, books, magazines, newspaper, trade journals etc.

Collection of Primary Data

Primary data is collected in the course of doing experimental or descriptive research by doing experiments, performing surveys or by observation or direct communication with respondents. Several methods for collecting primary data are given below –

1. Observation Method

It is commonly used in studies relating to behavioural science. Under this method observation becomes a scientific tool and the method of data collection for the researcher, when it serves a formulated research purpose and is systematically planned and subjected to checks and controls.

(a) Structured (descriptive) and Unstructured (exploratory) observation – When a observation is characterized by careful definition of units to be observed, style of observer, conditions for observation and selection of pertinent data of observation it is a structured observation. When there characteristics are not thought of in advance or not present it is a unstructured observation.

(b) Participant, Non-participant and Disguised observation – When the observer observes by making himself more or less, the member of the group he is observing, it is participant observation but when the observer observes by detaching himself from the group under observation it is non participant observation. If the observer observes in such a manner that his presence is unknown to the people he is observing it is disguised observation.

(c) Controlled (laboratory) and Uncontrolled (exploratory) observation – If the observation takes place in the natural setting it is a uncontrolled observation but when observer takes place according to some pre-arranged plans, involving experimental procedure it is a controlled observation.

Advantages

? Subjective bias is eliminated
? Data is not affected by past behaviour or future intentions
? Natural behaviour of the group can be recorded

Limitations

? Expensive methodology
? Information provided is limited
? Unforeseen factors may interfere with the observational task

2. Interview Method

This method of collecting data involves presentation of oral verbal stimuli and reply in terms of oral – verbal responses. It can be achieved by two ways :-

(A) Personal Interview – It requires a person known as interviewer to ask questions generally in a face to face contact to the other person. It can be –

Direct personal investigation – The interviewer has to collect the information personally from the services concerned.

Indirect oral examination – The interviewer has to cross examine other persons who are suppose to have a knowledge about the problem.

Structured Interviews – Interviews involving the use of pre- determined questions and of highly standard techniques of recording.

Unstructured interviews – It does not follow a system of pre-determined questions and is characterized by flexibility of approach to questioning.

Focused interview – It is meant to focus attention on the given experience of the respondent and its effect. The interviewer may ask questions in any manner or sequence with the aim to explore reasons and motives of the respondent.

Clinical interviews – It is concerned with broad underlying feeling and motives or individual’s life experience which are used as method to ellict information under this method at the interviewer direction.

Non directive interview – The interviewer’s function is to encourage the respondent to talk about the given topic with a bare minimum of direct questioning.

Advantages

? More information and in depth can be obtained
? Samples can be controlled
? There is greater flexibility under this method
? Personal information can as well be obtained
? Mis-interpretation can be avoided by unstructured interview.

Limitations

? It is an expensive method
? Possibility of bias interviewer or respondent
? More time consuming
? Possibility of imaginary info and less frank responses.
? High skilled interviewer is required

(B) Telephonic Interviews – It requires the interviewer to collect information by contacting respondents on telephone and asking questions or opinions orally.
Advantages –

? It is flexible, fast and cheaper than other methods
? Recall is easy and there is a higher rate of response
? No field staff is required.

Limitations –

? Interview period exceed five minutes maximum which is less
? Restricted to people with telephone facilities.
? Questions have to be short and to the point
? Less information can be collected.

3. Questionnaire

In this method a questionnaire is sent (mailed) to the concerned respondents who are expected to read, understand and reply on their own and return the questionnaire. It consists of a number of questions printed on typed in a definite order on a form on set of forms.

It is advisable to conduct a `Pilot study’ which is the rehearsal of the main survey by experts for testing the questionnaire for weaknesses of the questions and techniques used.

Essentials of a good questionnaire –

-It should be short and simple

-Questions should proceed in a logical sequence

-Technical terms and vague expressions must be avoided.

-Control questions to check the reliability of the respondent must be present

-Adequate space for answers must be provided

-Brief directions with regard to filling up of questionnaire must be provided

-The physical appearances – quality of paper, colour etc must be good to attract the attention of the respondent

Advantages

? Free from bias of interviewer
? Respondents have adequate time to give
? Respondents have adequate time to give answers
? Respondents are easily and conveniently approachable
? Large samples can be used to be more reliable

Limitations

? Low rate of return of duly filled questionnaire
? Control over questions is lost once it is sent
? It is inflexible once sent
? Possibility of ambiguous or omission of replies
? Time taking and slow process

Collection of Secondary Data

A researcher can obtain secondary data from various sources. Secondary data may either be published data or unpublished data.

Published data are available in :

a. Publications of government
b. technical and trade journals
c. reports of various businesses, banks etc.
d. public records
e. statistical or historical documents.

Unpublished data may be found in letters, diaries, unpublished biographies or work.

Before using secondary data, it must be checked for the following characteristics –

1. Reliability of data – Who collected the data? From what source? Which methods? Time? Possibility of bias? Accuracy?

2.Suitability of data – The object, scope and nature of the original enquiry must be studies and then carefully scrutinize the data for suitability.

3.Adequacy – The data is considered inadequate if the level of accuracy achieved in data is found inadequate or if they are related to an area which may be either narrower or wider than the area of the present enquiry.

Advantages & Disdavantages:

One of the advantages of the secondary data is that it is easily available and hence less time is required to gather all the relevant information. Also, it is less expensive than the primary data. But however the data might not be specific to the researcher’s needs and at the same time is incomplete to reach a conclusion.

Also, the authenticity of the research results might be skeptical. The data may be out of date or inaccurate. If using data collected for different research purposes, it may not cover those samples of the population researchers want to examine, or not in sufficient detail. Administrative data, which is not originally collected for research, may not be available in the usual research formats or may be difficult to get access to.

Explain ethics in conducting research and how ethics is applies when collecting data.

Ethics focuses on the disciplines that study standards of conduct, such as philosophy, theology, law, psychology, or sociology. Thus, data collection for any research should also be done under some ethical codes to get unbiased & conclusive results.

The following is a rough and general summary of some ethical principals that various codes address:

Honesty

Strive for honesty in all scientific communications. Honestly report data, results, methods and procedures, and publication status. Do not fabricate, falsify, or misrepresent data. Do not deceive colleagues, research sponsors, or the public.

Objectivity

Strive to avoid bias in experimental design, data analysis, data interpretation, peer review, personnel decisions, grant writing, expert testimony, and other aspects of research where objectivity is expected or required. Avoid or minimize bias or self-deception. Disclose personal or financial interests that may affect research.

Integrity

Keep your promises and agreements; act with sincerity; strive for consistency of thought and action.

Carefulness

Avoid careless errors and negligence; carefully and critically examine your own work and the work of your peers. Keep good records of research activities, such as data collection, research design, and correspondence with agencies or journals.

Openness

Share data, results, ideas, tools, resources. Be open to criticism and new ideas.

Respect for Intellectual Property

Honor patents, copyrights, and other forms of intellectual property. Do not use unpublished data, methods, or results without permission. Give proper acknowledgement or credit for all contributions to research. Never plagiarize.

Confidentiality

Protect confidential communications, such as papers or grants submitted for publication, personnel records, trade or military secrets, and patient records.

Responsible Publication

Publish in order to advance research and scholarship, not to advance just your own career. Avoid wasteful and duplicative publication.

Responsible Mentoring

Help to educate, mentor, and advise students. Promote their welfare and allow them to make their own decisions.

Respect for colleagues

Respect your colleagues and treat them fairly.

Social Responsibility

Strive to promote social good and prevent or mitigate social harms through research, public education, and advocacy.

Non-Discrimination

Avoid discrimination against colleagues or students on the basis of sex, race, ethnicity, or other factors not related to scientific competence and integrity.

Competence

Maintain and improve your own professional competence and expertise through lifelong education and learning; take steps to promote competence in science as a whole.

Legality

Know and obey relevant laws and institutional and governmental policies.

Animal Care

Show proper respect and care for animals when using them in research. Do not conduct unnecessary or poorly designed animal experiments.

Human Subjects Protection

When conducting research on human subjects, minimize harms and risks and maximize benefits; respect human dignity, privacy, and autonomy; take special precautions with vulnerable populations; and strive to distribute the benefits and burdens of research fairly.
