- Data is a collection of facts that can be qualitative (descriptive information) or quantitative (numerical information). It can come from primary sources through first-hand collection or secondary sources that are already available. - Common data collection methods include observation, interviews, questionnaires, and documentary analysis. Observation involves direct observation while interviews can be structured, semi-structured, or informal. Questionnaires use a set of questions to gather responses. - Motivation research techniques like word association tests, sentence completion tests, and projective techniques aim to uncover hidden motives through indirect questioning and use of pictures/stories.

- 2. WHAT IS DATA? “Data is a collection offacts.” Such asnumbers, words, measurements, observations or even just descriptions of things.
- 3. Qualitative data isdescriptive information (it describessomething) Quantitative data, isnumerical information (numbers). Discrete data can only takecertain values (like whole numbers) Continuous data cantake any value (within arange)
- 4. EXERCISE What type of data is it (about dog)? 1. Hehas4 legs 2. Hehaslots of energy 3. Heis brown and black 4. Heweighs 25.5 kg 5. Hehas2 brothers 6. Hehaslong hair 7. Heis 565 mm tall
- 5. SOURCES OF DATA 1. Primary Data – Thedata collected first hand by researcher for his research 2. Secondary Data – Thedata which is already collected bysomeone – It is readymadedata

- 7. OBSERVATION • Study relating to BehavioralScience • Information is sought by way of investigator’s own direct observations • Respondent is not asked/communicated. • Willingness of respondent to respond is not necessary • Lessdemanding of active cooperation
- 8. •Limitations: 1.Expensive 2.Limited Data 3.Can’t observe what is going on in mind 4.Some people are rarely accessible OBSERVATION
- 9. OBSERVATION •Things to keep in mind: 1.What should be observed? 2.How observation should be made and recorded? 3.How to ensure accuracy?
- 10. OBSERVATION •Participant and non-participant: Participant Researcher is a member of group that he/she observes. Ex: Going in slum and living their life. Non - participant Researcher is detached from the group he/she observes. Ex: Study of slum people without being itspart/member
- 11. OBSERVATION •Naturalistic and Simulations: Observation in a natural setting >Uncontrolled •Ex. study of consumers in amall Observation in predefined environment >Controlled •Simulatesor recreatesa situationor environment
- 12. INTERVIEW
- 13. STRUCTURED INTERVIEW The researcher has a specific set of questions designed to elicit responses from the participants. SEMI-STRUCTURED INTERVIEW The researcher prepares open-ended questions in which the participants are free to write their responses.
- 14. INFORMAL INTERVIEW To determine how the participants act on certain situations. RETROSPECTIVE INTERVIEW Done to recall and reconstruct something that happened in the past.
- 15. TYPES OF INTERVIEW QUESTIONS 1. Background Questions – includes education, age, previous work, etc. 2. Knowledge Questions – factual information 3. Experience Questions – what the participant is doing presently or in the past. 4. Opinion Questions – how the participants think on certain topics or issues. 5. Feeling Questions – emotional responses of the participants on their experience. 6. Sensory Questions – what the respondent has seen, tasted, heard, touched, or smelled.
- 16. PREREQUISITES OF INTERVIEW 1. Interviewers should be carefully selected, trained andbriefed. 2. Honest, sincere, hardworking, impartial, unbiased 3. Must possesstechnical competence 4. Practical experience 5. Create friendly atmosphere of trustand confidence 6. Recording responses accurately and completely 7. Interviewer should not show surprise ordisapproval 8. Should not argue 9. Keepthings on track
- 17. • Guidelines: – Askall questions in schedule – Repeat question if not understood – Don’t show disapproval/surprise – Listen quietly with patience – Neither argue nor dispute – Show genuine concern and interest – Don’t reveal your own opinion or reaction – Keepconversation on track – Thank with a smile when done Carrying the interview
- 18. FOCUS GROUP DISCUSSION – can provide multiple perspectives at a time DOCUMENTARY ANALYSIS – studies human behavior indirectly by analyzing documents
- 19. QUESTIONNAIRE
- 20. WHAT IS QUESTIONNAIRE? “Adocument containing set of questions logically related to the problem under study.” • If the questions are filled by respondents, then its calledas ‘Questionnaire’ • If filled by interviewer, it’s called as ‘Schedule’
- 21. QUESTIONNAIRE ADVANTAGES • Free from bias of interviewer • Respondents have adequate time • Large samples can be used to get more dependable and reliable data DISADVANTAGES • Used only when respondent is educated and cooperating • Control over questionnaire is lost once it is sent • Time and cost
- 22. QUESTION CONSTRUCTION 1. Question Relevance • Should be relevant to researchobjectives • Question should be able to answer researchproblem • Single question may not be able to answer problem or attain objective • Respondents should know the answer • Question should not test respondents recallability • Should be easily understandable. • Should be specific
- 23. QUESTION CONSTRUCTION 2. Question Wording • Vocabulary : Useof common vocabulary • Exactness : Do you usually go to gym? Vs.How many days in a week do you go to gym? • Simplicity : Simple words and sentence construction, avoidjargons • Neutrality : Should not cause undue influence. E.g. You prefer Brewed over Nescafe,right? • Presumption : Shouldn’t presume about respondent E.g. How many times a day do you drink coffee? • Hypothetical Questions : Avoid. E.g. What would you do if …. ? • Embarrassing Questions : PersonalQuestions
- 24. 3. Types of Questions • Open Ended –Free Scope for respondents to answer –Used to explore more and in depth information –Difficult to analyze –E.g. What are your career plans after post graduation
- 25. 3. TypesofQuestions • Closed Ended – Dichotomous • Canbe answered with 2 responses • E.g. Do you own or rent yourhouse? • Do you like Marathi movies? – Multiple Choice Questions • More than 2 alternatives for onequestion • E.g. Which brand of jeans do youprefer? • MCQmust contain all the possible choices • Should not contain overlapping choices • Alternatives should be reasonable
- 26. QUESTION CONSTRUCTION 4. Question Order or Sequence • One question should follow another in logicalsequence • Sequence should have relation E.g. What is volume of your trading? How many trades do you make in a week?
- 27. QUESTION CONSTRUCTION Types of questions to beavoided • Leading Questions : Influences respondent togive acertain answer E.g.Are you against giving too much power to thetrade unions? • Loaded Questions : Contains words which are emotionallycolored.

- 30. ACTIVITY : Briefly describe each data collection strategy a.Observation b.Interview c.Focus group discussion d.Documentary analysis
- 32. TECHNIQUES OF MOTIVATION RESEARCH Projective T echniques Depth Interviews
- 33. • Testis conducted to establish the personalities of the respondents and their reactions. • Theyproject or reflect the subject’s thought about what he or shesees, feels, perceives thus producing the reactions. Therearefive most commonlyadministeredtests of this kind namely: 1. WordAssociation Test 2. SentenceCompletion Test 3. Story Completion Test 4. Third PersonTest 5. Pictorial Techniques Projective Techniques
- 34. WORD ASSOCIATION TEST • Word association test is a list of words ranging from twenty-five to seventy-five is given. • Theword suggestedby the researcher is to be associated by the respondent by the most fittingword he thinks. • Thisis widely used to measure the effect ofthe brand namesand advertising messages. • Here,it is not possible to give all the seventy-fivewords. On illustrative basis, let us have fifteen words: 6.Two-wheelers………… 7.Four-wheelers………… 8. Tyre… … … … … … … … … 9. Glasswares…………. 10. Ink……….. 11. Pencils………… 12.Fridges……………………. 13.
