- 2. Data •Any information that has been collected, observed, generated or created to research finding. Types of research Data - 1. Quantative data – based on number. 2. Qualititative data- based on categories
- 3. What is Data Collection? • It is the process by which the researcher collects the information needed to answer the research problem.
- 4. The Purpose of Data Collection The purpose of data collection is – •To obtain information •To keep on record •To make decision about important issue •To pass information on to other.
- 5. Methods of Data Collection •Essentialy Two Types: • PRIMARY DATA •Primary data are those which are collected for the first time and are original in character. • SECONDARY DATA •Secondary data are those which have already been collected by someone else.
- 6. Primary Data v/s Secondary Data
- 7. •Primary Data may be collected through:- Observation Interviews Questionnaires Schedules Methods of Collecting Primary Data
- 8. Observation Method •Observation method is a method under which data collected with the help of observation by the observer. Types of Observation Methods- •Structured •Unstructured •Participant •Non-Participant
- 9. 1.Structured Observation- •Systemic observation. •For structured observation the researcher specifies in details what is observed and how the measurement are to be recorded. 2. Unstructured Observation- • Observe and record behavior in a holistic way without the use of pre determined guide.
- 10. 3- Participant Observation • When the observer is member of the group which he is observing then it is Participant Observation. 4- Non-Participant Observation • When the observer is not a member of the group. • observer is observing people without giving any information to them then it is Non-Participant Observation.
- 11. Advantages - •Produces Large quantities of data. •All data obtained from observations are usable. •The observation technique can be stopped or begin at any time. •Relative Inexpensive. Disadvantages- • Time consuming • Limited information • Extensive Training is needed. • Not use for studying past events or activities.
- 12. Interview Method •Interview is a process of communication or interaction between two person to collect the relevant information for the research.
- 13. Types of interview method 1. Personal Interview , it can be— • Structured • Unstructured 2. Telephonic Interview
- 14. Advantage •More information at greater depth can be obtained •The interviewer can judge the non-verbal behavior of the respondent. •The interviewer can control over the order of the question, as in the questionnaire, and can judge the spontaneity of the respondent as well. •Personal information can be obtained https://www.sociologygroup.com/advantages-disadvantages-interview-research/
- 15. Disadvantage •It is an expensive Method •Interviewer bias •Respondent bias •Time consuming •There is a lack of accessibility to respondents https://www.sociologygroup.com/advantages-disadvantages-interview-research/
- 16. Questionnaires •Questionnaire is as an instrument for research. • It consists of a list of questions, along with the choice of answers, printed or typed in a sequence on a form used for acquiring specific information from the respondents. •Questionnaires are delivered to the persons concerned either by post or mail, requesting them to answer the questions and return it. https://thebiologynotes.com/questionnaire-method-of-data-collection/
- 18. Advantage of Questionnaire •Questionnaires lies in their uniformity i.e. all respondents see exactly the same questions. •It is an inexpensive method. •Free from the bias of the interviewer, as the respondents answer the questions in his own words. •Respondents have enough time to think and answer. •Due to its large coverage, respondents living in distant areas can also be reached conveniently. •Large samples can be used. https://thebiologynotes.com/questionnaire-method-of-data-collection/
- 19. Disadvantage Of Questionnaire •Time consuming •The respondents need to be educated and cooperative •Possibility of unclear replies. •The rate of non-response is high. https://thebiologynotes.com/questionnaire-method-of-data-collection/
- 20. Schedules •Schedule is the tool or instrument used to collect data from the respondents while interview is conducted. •In schedules there is an enumerator who filled the questionnaire. •Enumerator goes to the respondents, asks them the questions from the Questionnaire in the order listed, and records the responses in the space provided. •Enumerator must be trained in administering the schedule.
- 21. Difference b/w Questionnaire and Schedule Questionnaire It is generally send to through mail and no further assistance from sender. It is cheaper method. Non response is high. In questionnaire, it is not confirmed that expected respondent have filled the answers. Schedule Schedule is filled by the enumerator or research worker. Costly requires field workers. Non response is low. In schedule identity of person is known.
- 22. Secondary Method Of Data Collection • Data gathered and recorded by someone else • It involves less cost, time and effort. • Secondary data is data that is being reused. Usually in a different context. • For example: data from a book, magazines and newspaper. • It can be collected from internal or external sources.
- 23. •Internal Sources- •Sales Records •Marketing Activity •Cost Information •Distributor reports and feedback •Customer feedback
- 24. •External Source- •Journals •Books & Magazines •Newspaper •Libraries •The Internet or website •Published data by govt. or private organisation •Census ,etc.
- 25. Factors to be considered before using secondary data • Reliability of data - Who, when , which methods, at what time etc. must be investigated. • Suitability of data – Object ,scope, and nature of original inquiry should be studied, as if the study was with different objective then that data is not suitable for current study • Adequacy of data– Level of accuracy,area differences then data is not adequate for study
- 26. Advantage of Secondary Data Collection •Ease of access •Low cost or free •Time-saving •Allow you to generate new insights from previous analysis •Longitudinal analysis •A huge amount of secondary data with a wide variety of sources https://www.intellspot.com/secondary-data/
- 27. Disadvantage Of Secondary Data •Might be not specific to your needs •You have no control over data quality •Biasness •Not timely https://www.intellspot.com/secondary-data/
- 28. Selection of proper Method for collection of Data •Nature ,Scope and object of inquiry •Availability of Funds •Time Factor •Accuracy Required
