Data collection

  1. 1. Data Collection
  2. 2. Data Sources• Primary Data structures of variables that have been specifically collected and assembled for current research problem or opportunity situation.• Secondary Historical data structures of variables that have been previously collected and assembled for some research problem or opportunity situation other than the current situation.
  3. 3. Secondary DataDisadvantages• Authenticity and accuracy of data are difficult to know• May be obsolete and not up-dated• May not be properly arranged, compiled and presented• Units may be different and ambiguousAdvantages• Cost-effective, sometimes even available free of any expenditure• Time saving• Needs much less effort• Familiarity with this data indicates the fallacies, deficiencies and gaps, as a result of which the researcher becomes aware and alert while collecting primary data• Dealing with this data may lead to a better comprehension of and provide useful insights into the research problem• Used as a basis for comparison with primary data• Occasionally more accurate than primary data• Information may be available only from this data and there may be no recourse to primary data
  4. 4. Criteria & CautionCriteria for Evaluating Secondary Data• Do the data help answer the questions?• Do data apply to population, geographical area and time period of interest?• Can the units and classifications presented apply?• Is it possible to go to the origin of the data?• Is the cost of data acquisition worth it?• Accuracy? Can the accuracy be tested?• Is it from a trusted source? Authentic?• Is using the data worth the risk?Caution prior to using secondary data• data should answer the research questions• data should pertain to the appropriate population, geographical area, category of socio-economic class and time period• the units and classifications with which the data is presented should apply• if required the researcher should have access to the origin of the data• the cost of data acquisition should be worth it• the accuracy of the data should be made sure• it should be possible to test the accuracy of the data• data should be from a trusted source and be authentic• if acquiring the data requires some time, the waiting should be worthwhile and the time gap should not change the research scenario
  5. 5. Sources and Classification of Secondary DataInternal Sources External Sources•Sales records•Credit records•Internal reports Published Commercial •Directories •Demographic •Periodicals •Store Audit •Financial & Statistical Records
  6. 6. Primary data for Qualitative ResearchDirect – non-disguised• Interview method• Focus group discussions• Delphi techniqueIndirect - disguised• Projective technique
  7. 7. Interview• formalised process• well-trained interviewer asks a subject• set of structured, semi-structured and open ended questions• in a face-to-face setting.Steps to be taken prior to conducting an interview• Determine the topic, objective and purpose of the research.• Decide and identify the interviewees• Seek appointments with the interviewees, preferably according to their convenience.• Prepare a list of factual as well as open-ended questions before the interview• The questions should be written on a piece of paper and additional papers should be carried so as to make notes as and when required.
  8. 8. Kinds of Questions• Factual questions - age, gender, education, ethnicity, family structure, country of birth, migration, etc.• Open-ended questions help to bring out the interviewee’s memories, feelings, attitudes, perceptions, etc. about a certain topic. Example- ‘What are your anticipations and expectations from the forthcoming budget?’
  9. 9. Steps to be taken while conducting an interview• The interviewees should be explained clearly about the purpose of the questions and how the research will benefit from their answers.• Notes must be taken from the answers, sometimes summarising the answers received and sometimes quoting them verbatim.• Many interviewers make audio recording of the interview, making sure to get permission from your interviewee first.• As much as possible should be gathered from the interview – the interviewee should be permitted to talk and give his own opinion.• The final and vital step is to thank the interviewees and let them know your gratitude for the information they have contributed towards the research.
  10. 10. In an interview of the probing kind• The interviewee’s initial response to a specific question is taken• This response is used as the guide line and frame work for the next question(s)• More detailed responses are derived from these question(s)Essential qualities of the interviewer• Interviewer should be fully aware of the what and why of research being conducted• The venue and time of the interview should be selected so that they suit the interviewee• Approach should be informal with a slight firmness• All possible effort should be made to make a good rapport• Communicating, listening and understanding skills must be very good• The interviewee should feel that the interview is a pleasant experience rather than a harrowing and compelling one
  11. 11. Characteristics of questions in an interview• Questions that give one-word, yes-or-no answers should be avoided. They should rather be replaced with open- ended questions Example “What games do you play?” will get you more information than “Do you play cricket?”• The questions should be asked in clear pronunciation and smooth accent.• Language of the questions should never be offensive.• Words should be chosen with care.• If the interviewee fails to understand the meaning of a question, it must be explained in simpler language or translated into a language with which he is familiar and comfortable with.
  12. 12. Kinds of QuestionsOpen-ended questionsGive us a window into what the respondent is thinking and feeling.Examples• Tell me about your home.• What do you think would happen if -------?Closed-ended questions• Allow us to get definite answers and move toward closing the interview.• Start with verbs, such as "Are...?" "Will...?" "Is...?" "Have...?" "Did...?" and even contractions such as "Arent...?" "Didnt...?" and "Wont...?"• This is often called a convergent question.• It brings conversation gradually to a convergence (begin narrowing the conversation) on a single point or decision.• A closed-ended question is answered with a "yes" or a "no."
  13. 13. Probing questions• To know how the respondent has reached particular conclusions,• To consider and weigh diverse evidence,• To examine the validity of their own deductions and inductions,• To consider opposing points of view.Examples• Why do you think Indian brands succeed in the world market?• Can you elaborate?• What evidence can you present to support your answer?Double-barreled questions combine two or more issues in a single question. AVOID• Does the question include the word "and"?• Answers to double-barreled questions are ambiguous because two or more ideas are confounded.Examples• Why do you think Indian brands succeed and flourish in the world market?• Do you like and enjoy shopping in Supermarkets and Malls?
  14. 14. Focus Group Discussions• - formalised process – of bringing a small select group of people together – for an interactive and spontaneous discussion – on one particular topic or conceptObjectives• Provide data for defining and redefining research problems• Identify specific hidden information requirements• Reveals hidden – needs, wants, preferences – attitudes, feelings, behaviours – perceptions, opinions• Generate new ideas• Discover new constructs and measurement methods• Understand sudden changes
  15. 15. Advantages• May give insights into not just what participants think, but also why they think it.• Can reveal consensus and diversity of the different needs, experiences, preferences, and assumptions of the participants.• Allows interaction among participants – enabling each to take clues from others and thus augmenting and opposing each others ideas and comments to provide an in-depth view not attainable from individual questioning.• Unexpected comments and opinions and can be explored easily.• New perspectives and avenues open up.• A warm and healthy rapport between the moderator and the participants can encourage the latter to express their feelings fully, candidly and honestly.Disadvantages• Group sizes are typically small and may not be representative of the target population.• If the potential participants live in geographically distant regions, getting them to congregate at the same place at the same time may be difficult.• The information collected may have an inclination to be biased by subjective interpretation than is the case with quantitative methods.• More outspoken and ‘confident’ participants can dominate the discussion.• Viewpoints of less assertive and rather quiet people often are difficult to assess.
  16. 16. Steps in conducting an FGD• Planning• Conducting• Analysing and reporting results
  17. 17. Planning• Have a thorough idea of the possible uses to which the findings of the FGD will be put.• Identify and select participants with the appropriate profile - participants who represent the target population. Homogenous groups help to create a sense of comfort and compatibility among participants.• The group size of an FGD should range between 5 and 12. This size group gives everyone a chance to participate, while providing enough diversity of opinion for a well-rounded perspective. A smaller group should be made when the need is to obtain more depth and detail of information and / or the participants have a lot to contribute to the purpose of the research.• The number of sessions is usually restricted to one, but can be increased if the need rises• Duration of sessions depend on the intricacy of the research and involvement of the participants. But as a rule of the thumb sessions should last between 1 to 3 hours.• The meeting time and venue of the FGD should left to the discretion of the participants.
  18. 18. Conducting• The moderator should be the one who knows how to and is competent enough to work with a group of people. He should be able to encourage full participation and interaction among the participants.• A person acting as an observer or recorder should record all comments made and opinions aired by the group (using an audio tape or video recorder is advised) and note any significant gestures or behaviour.• The identity of the moderator is never revealed to the participants throughout the course of the FGD, lest they become conditioned.• The session should begin with an introduction of the participants to each other.• The purpose and the main objective of the FDG should be briefly explained to the participants.• The main session of the FGD should be carefully conducted and should be moulded towards the direction which will serve the purpose of the FGD.• Concluding the session should be with a vote of thanks by the moderator addressed to all other members of the FGD, with special mention of the participants.
  19. 19. Analysing and reporting results• After completion of the FGD, the task of the researcher is to sit with the moderator and observer and carefully and meticulously scan the proceedings of the FGD – notes, conversation, audio and video recordings. They should pay special emphasis on1. Words2. Comments3. Frequency of comments4. Intensity of comments5. Special mentions• Interpreting each of the above in a correct way with reference to the topic of the FGD and more so to the research is very essential for the fulfillment of the research.
  20. 20. The moderator• Although every member of an FGD play important roles in the successfully conducting it, the part the moderator plays is the most vital.• The moderators job is to encourage discussion and lead the FGD in the proper direction.• His job is also to maintain focus, so that the discussion does not go too astray from the essentials.• But, too much moderator control and intervention might lead to a situation, where the participants find difficult or reserved to express their own perspectives.• Whereas, too little moderator control means that less about the topic may be discussed.• Thus, moderator must play his role optimally, judiciously and informally but sternly.• Moderators need specialised training to become so.
  21. 21. Funnel Structure FGD The beginning section is broad and less structured. The goal is to hear participants general perspectives. The middle section is more structured, and the goal is to lead into, or begin to cover, the topics of most interest to you.The ending section is narrow and the most structured. The goalis to obtain answers to your specific needs assessment questions.The final question in a focus group oftenreturns to a broader, more general wrap-up.
  22. 22. Sitting Arrangement in FGD
  23. 23. Projective techniquesThis is a specialised method of data collection,where one to one unstructured interview isconducted with the target individual at a placewhere they are in their natural environment, e.g.their home or recreation club. – This technique enables understanding the targets behaviour within the context of his own world. – When a researcher uses projective techniques, he asks an informant to react to some kind of visual or verbal stimulus.
  24. 24. • Example: An informant may be provided with a rough outline of the body and be asked to draw her or his perception of the conception or onset of an illness.• Another way of a projective technique is the presentation of a hypothetical question or an incomplete sentence or story to the respondent. The researcher may ask the respondent to complete in writing sentences or give an outline of the story etc.• Example 1– ‘If I were to discover that my neighbour had TB, I would feel ------------------------------------.’• Example 2 – ‘The following picture series refers to the population explosion in certain rural parts of India.• Word association test• Sentence completion test• Thematic apperception test (TAT)• Third-person techniques
  25. 25. Word Association Test• A list of words or phrases can be presented in random order to respondents, who are requested to state or write the word or phrase that pops into their mind;• Respondents are asked for what word or phrase comes to mind immediately upon hearing certain brand names;• Similarly, respondents can be asked about slogans and what they suggest;• Respondents are asked to describe an inanimate object or product by giving it "human characteristics" or associating descriptive adjectives with it.• For example, a group of tourism professionals working on establishing a strategic marketing plan for their community were asked to come up with personality traits or "human characteristics" for the villages as well as the cities within their area:• Villages – Serene – Conservative – Quaint – Friendly – Accessible – Reliable• Cities – Brash – Rushed – Liberal – Modern – Cold• Most of the tourism industry representatives came from the cities and had strongly argued that the urban areas had historically been neglected in promotional campaigns. As a result of this and other exercises, they came to the realization that the rural areas were a strong feature of the overall attractiveness of the destination and needed to be featured as key elements in any marketing campaign.
  26. 26. Sentence Completion Test• In the sentence completion method, respondents are given incomplete sentences and asked to complete the thought. These sentences are usually in the third person and tend to be somewhat ambiguous. For example, the following sentences would provide striking differences in how they were completed depending on the personality of the respondent:"A beach vacation is……………………""Taking a holiday in the mountains is….""Golfing is for…""The average person considers skiing…..""People who visit museums are…………"• Generally speaking, sentence completion tests are easier to interpret since the answers provided will be more detailed than in a word association test. However, their intent is also more obvious to the respondent, and could possible result in less honest replies.• A variant of this method is the story completion test. A story in words or pictures is given to the respondent who is then asked to complete it in his/her own words.
  27. 27. Thematic Apperception Test (TAT)In the Thematic Apperception Test (TAT), the respondents are shown one or more pictures and asked to describe what is happening, what dialogue might be carried on between characters and/or how the "story" might continue. For this reason, TAT is also known as the picture interpretation technique.
  28. 28. Third Person TechniqueBy providing respondents with theopportunity to talk about someoneelse, such as a neighbor, a relative or afriend, they can talk freely aboutattitudes that they would notnecessarily admit to holdingthemselves.
  29. 29. Quantitative Research ProcedureQuestionnaire• set of questions and scales• following a particular logic• designed to generate enough raw data• accomplishing the research objectives
  30. 30. Steps in development of Questionnaires• Research objectives transformed to information objectives• Determine appropriate data collection method(s)• Determine information requirements for each objective• Develop specific question / scale measurement formats• Establish flowerpot format and layout• Draft the questionnaire• Obtain respondent’s approval• Pretest and revise questionnaire• Finalise the draft of the questionnaire• Implement survey
  31. 31. Four components of a QuestionnaireWords should be devoid of ambiguity, abstraction, connotation, difficultyExample – A question with reference to a research concerning use of telephones can be formatted in the following ways: question meaning Do you think anything could be done about the Be able to, permitted to non-availability of telephone extensions? Do you think anything should be done about the command non-availability of telephone extensions? Do you think anything might be done about the Expressing possibility, non-availability of telephone extensions? permission, wish Do you think anything must be done about the Be obliged, be certain to non-availability of telephone extensions?
  32. 32. Questions• Unstructured questions are open ended questions formatted to allow respondents to reply in their own words• Structured question - alternatives are suggested and the respondent is forced to choose among the alternatives – which might sometimes lead to a question with no answer.Example - What toppings do you like on your Pizza? cottage cheese sautéd vegetables mushroom cheddar cheese garlic barbecued chicken shredded vegetables grilled beef• The respondent may not choose any one of the above alternatives• He may no know that ‘panir’ is termed as cottage cheese in English• He may not be aware of the technical meaning of sautéd• He may be offended by ‘grilled beef’, because of his religious prejudices• He may not have tasted mushroom earlier
  33. 33. Structured questions are also options closed ended questions that require scale points for each cottage cheese 1 2 3 4 5 6 7 alternativeExample – Please rate each of the following pizza toppings as per sautéd 1 2 3 4 5 6 7 vegetables your liking1 for ‘not like at all’ and 7 for ‘like mushroom 1 2 3 4 5 6 7 very much’ cheddar 1 2 3 4 5 6 7 cheese garlic 1 2 3 4 5 6 7 barbecued 1 2 3 4 5 6 7 chicken shredded 1 2 3 4 5 6 7 vegetables
  34. 34. Unstructured question - the respondent does not have to choose from a predetermined set of responses, rather he is free to give any answer he feels pertinent.• Example - What toppings do you like on your Pizza? ____________________, ____________________,• ________________________, _____________________________, __________________________3) Make questionnaire very simple, friendly for you, respondent, your replacement, future use• Bad questions• Incomprehensible to respondent - wording and/or concept cannot be understood• Unanswerable - respondent does not have access to the information needed or the answer choices do not apply to respondent• Leading - respondent is forced or directed into a response he would not have ordinarily given if all possible concepts / information / facts were provided• Double-barrelled - addresses more than one issue at a time• Bombastic words - unnecessary use of “sophisticated” words where easy to understand common words could be substituted
