Tools and methods of data collection

  2. 2. The word data is a pleural form of the word datum which means information that is systematically collected in the course of the study. Data are observable and measurable facts that provide information about the phenomenon under study. Data collection is the process by which the researcher collects the information needed to answer the research problem. DATA
  3. 3. DATA sources PRIMARY SOURCES SECONDARY SOURCES INTERNAL SOURCES (Private documents) EXTERNAL SOURCES (Public documents) Published Sources Unpublished Sources People, objects, programmes, institutions, etc  Biographies  Diaries  Letters  Memories  Journals & magazines  Newspaper  Government reports  Statistical abstracts  Census reports  Mass communication  Communication reports  Unpublished thesis  Unpublished dissertation and reports  Officials or patients record

  9. 9. DEFINITION 1) Interview method is a method of data collection in which one person (interviewer) asks the questions from another person (respondent) which is conducted either face to face or telephonically. 2) An interview is a conversation between two or more people (interviewer & interviewee) where questions are asked by interviewer to obtain information from the interviewee.
  10. 10. CHARACTERSTICS OF INTERVIEW • The participants, the interviewer and respondents are strangers. • The relationship between the participants is a transitory one. • Interview is a mode of obtaining verbal answers to question put verbally. • Investigators records information's. • Interviews can be conducted over telephone also. • It is not always limited to a single respondents. • It is not a standarized process. It can be modified according to the situation.
  11. 11. BENEFITS OF INTERVIEW  Provide in depth and detailed information  Permits greater depth of response  Data form illiterate subjects  Higher responses  Clarify misunderstandings  Ask questions at several levels  Helps to gather other supplementary information  Use of special devices  Flexible and adequate  For people who are unable to write their responses interview is imporatant.
  12. 12. Types of interview  Structured Interview (Directive interview) Un-structured Interview (Non directive interview) Semi-structured Interview In Depth Interview Focused Group Interview Telephone Interview
  13. 13. Interviewing process Preparation of interview Pre interview introduction Developing rapport Carrying the interview forward Recording the interview Closing the interview
  14. 14. ADVANTAGES OF INTERVIEWS • It is useful to obtain information about people feelings, perceptions and opinions. • It allow more detailed questions to be asked. • High responses rate is achieved • Respondents own words are recorded. • Ambiguities can be clarified. • Meanings of questions can be clarified.
  15. 15. DISADVANTAGES • It is time consuming and costly. • High degree chances of interviews bias.
  16. 16. questionnaire METHOD
  17. 17. DEFINITION • A questionnaire is a structured instruments consisting a series of questions prepared by researcher that a research subject is asked to complete, to gather data form individuals about knowledge, attitude, beliefs & feelings. • A questionnaire is a structured self report paper and pencil instruments that a research subject is asked to complete.
  18. 18. TYPES OF QUESTIONNAIRE • OPEN FORMAT QUESTIONS Open ended questions are those questions which provide opportunity to the respondents to express their opinions and answer in their own way.
  19. 19. Examples- • Tell me about your relationship with yours friends. • What happened at the meeting? • How do get to work? • Why is it that every time I talk with you, you seem irritated? • Where do you want to be in five years?
  20. 20. CLOSED FORMAT QUESTIONS- These questions offers respondents a number of alternative replies, from which the subjects must choose the most likely matches the appropriate answer. A closed ended questions refers to any questions for which a researcher provide research participants with options from which to choose a responses.
  21. 21. 1. Dichotomous questions- these require the respondent to make a choice between two responses such as yes/no or male/female. Example 1. Have you ever been hospitalized? a. Yes b. No 2. Please enter you gender: a. Male b. Female
  22. 22. 2. Multiple choice question: these questions require respondents to make a choice between more than two responses alternatives. Examples 1. What is the basic functional unit of the kidney? a. Renal cortex b. Nephron c. Glomerulus d.Renal medulla 2. Who is known as Lady with the lamp? A. Mother teresa b. Sarojini naidu c. Florence nightingale d. None of these
  23. 23. 3. Cafeteria questions- these are a special type of multiple choice questions that ask respondents to select a response that most closely corresponds to their views. Examples 1. People have different view on family planning which of the following best represent your views? a. It is necessary to quality life. b. It is immoral and should be totally banned. c. It has undesirable side effects that suggests needs for caution. d. It is immoral and should be practiced.
  24. 24. 4. Rank order questions: these questions ask respondents to rank their responses from most favourable to least favourable. Example 1. What according to you is most important for your life. Rank from most favourable to least favourable. a. Money b. Education c. Family d. Health
  25. 25. 5. Contingency questions: a questions that is asked further only if the respondent gives a particular responses to previous questions. Examples 1. Do you have children under 18 at home? a. No b. yes, if yes please list ages 2. Did you buy anything in the hotel shop? a. Yes (go to Q. 10) b. no (go to Q. 13) What did you buy in the shop? a. Clothes b. Stationery c. Other d. Toys
  26. 26. 6. Rating questions: these questions ask respondents to judge something along an order dimensions. Respondents is asked to rate a particular issue on a scale that ranges from poor to good. They may provide a number of choices. Examples 1. How do you rate the following Very Poor Poor Ok Good Very Good a) Service b) Cleanliness c) Parking d) Quality of food e) Choice of food
  27. 27. 7. Importance questions: in this respondents are asked to rate the importance of a particular issue, on a rating scale of 1-5. this helps to know that the things/ issues that are important to a respondent. Examples- 1. Exercising every day is ………for the health. 1 2 3 4 5 Extremely important Very important Somewhat important Not very important Not at all important
  28. 28. 8. Likert questions: it help to know how strongly the respondents agrees with a particular statement. These question help to assess how respondents feels towards a certain issues/ services. 1. Person with multiple sex partners is at high risk of AIDS? 1 2 3 4 5 Strongly agree Agree Uncertain Disagree Strongly disagree
  29. 29. 9. Bipolar questions- are questions that have two extreme answers. Respondent has to mark his or her response between two opposite ends of the scale. Examples What is your balance of preference here? I like going for walks () () () () I like watching movie
  30. 30. 10. Matrix questions: it include multiple questions and identical response categories are assigned . Questions are placed one under another, forming a matrix. Response categories are placed under along the top and a list of questions down the side. Examples 1. How satisfied or dissatisfied are you with each of the following attributes? Very Satisfied Satisfied Neutral Dissatisfied Very Dissatisfied • Staff behaviour at the reception • Food quality • Speed of service • Behaviour of the waiter • Cost of the food items
  31. 31. Guidelines for designing a good questionnaire • It must be developed exactly in accordance with study objectives. • It should begin with the instructions for the respondents to provide the responses. • The questionnaire should be concise, precise and brief. • Language should be according to the respondents knowledge about a particular knowledge.
  32. 32. • Avoid professional jargons. • As far as possible open ended questions should be avoided. • Avoid questions with difficult concepts. • Controversial and ambiguous questions should be avoided. • questions which are likely to lead too bias in the respondents should be avoided.
  33. 33. ADVANTAGES OF QUESTIONNAIRE • Cost effective. • Easy to analyze. • Less time and energy to administer. • Reduce bias. • Used for large sample size.
  34. 34. DISADVANTAGES • Not suitable for all. • Low response rate. • It sent by mail may be filled by someone. • Its provide only superficial information. • Chances of misinterpretations. • People can lie and answer the questions vaguely.
  36. 36. DEFINITION • Composite scales are socio-psychological measurements, which are directed towards quantifying the qualitative attributes` such as feelings, attitude, self concepts, perceptions and beliefs etc. • Attitude scale is a special type of questionnaire designed to produce scores indicating the intensity and direction (for/against) of a person’s feelings about an object or event.
  37. 37. Likert scale • Likert scale was developed by psychologists Rensis likert in 1932 as a psychological concept measurement scale. • It scale was developed to measure the attitudes, values, and feelings of peoples. • Primarily original version of this scale is 5 point scales (strongly agree, agree, uncertain, disagree or strongly disagree). • How ever in recent times one can even observe the likert scale with 4 point scale (strongly agree, moderately agree, disagree, and uncertain) to 7 point scale (very strongly agree, strongly agree, agree, uncertain, disagree, strongly disagree and very strongly disagree).
  38. 38. definition • Likert scale is a composite measurement scale used to measure attitude, feelings and value of the people that involve summation of scores on the set of positive and negative declarative statements regarding measurable variables to which respondents are asked to indicate their degree of agreement or disagreement.
  39. 39. Use of likert scale • It scales used to measure the attitudes, values, and feelings of the people about specific concepts such as situation, peoples, places, objects, programmes, practices, policies and so on. • It may also be used to assess the opinions of the respondents. • This scale is used to have quantified measurement of the qualitative attributes of peoples such as feelings, values, beliefs.
  40. 40. Likert scale examples • Agreement Question: “The checkout process was straightforward” • Strongly Agree • Agree • Neither Agree Nor Disagree • Disagree • Strongly Disagree
  41. 41. • Likelihood Question: “I would recommend this product to my friends” • Very Likely • Likely • Neutral • Not Likely • Very Unlikely
  42. 42. • Satisfaction Question: “Please rate your satisfaction with your recent customer service experience:” • Very Happy • Somewhat Happy • Neutral • Not Very Happy • Not at All Happy
  43. 43. • Importance Question: “Rank each item in reference to its importance to you:” • Very Important, • Important • Moderately Important • Slightly Important • Not Important
  44. 44. Scoring of the likert scale Statement Strongly Agree Agree Uncertain Disagree Strongly Disagree Positive statement Person with multiple sex partners are at high risk of AIDS 5 4 3 2 1 Negative statement You can get AIDS by sharing utensils 1 2 3 4 5
  45. 45. ADVANTAGES • Easy to construct this scale. • More reliable and valid tool to measure the psychological variables. • Easy to administer, since respondents only have to tick in spaces. • Less time consuming during construction & administration.
  46. 46. DISADVANTAGES • Respondents may feel forced to answer the questions against all pre planned items and their categories. • Feelings of the respondents may not be fully assessed due to researcher’s pre planned statements and categories. • Difficulty in justifying the selection if the number of categories and numerical assignment to these categories. • Good attitude statements take time to construct.
  48. 48. SEMANTIC DIFFERENTIAL SCALE • The Semantic Differential Scale is a seven-point rating scale used to derive the respondent’s attitude towards the given object or event by asking him to select an appropriate position on a scale between two bipolar adjectives (such as “warm” or “cold”, “powerful” or “weak”, etc.) • Semantic differential scale is a type of rating scale designed to measure the connotative meaning of objects, events and concepts. These connotations are used to derive the respondents attitude towards the objects, events and concepts.
  49. 49. USE OF SEMANTIC DIFFERENTIAL SCALE • Patient satisfaction survey • Customer satisfaction survey • Employee survey • Marketing survey • Personality measurement • Clinical psychology
  50. 50. SEMANTIC DIFFERENTIAL SCALE likert scale
  51. 51. EXAMPLE OF SEMANTIC DIFFERENTIAL SCALE • Assess the belief about HIV/ AIDS HIV/ AIDS 1 2 3 4 5 6 7 1 2 3 4 5 6 7 1 2 3 4 5 6 7 1 2 3 4 5 6 7 1 2 3 4 5 6 7 cure death Social acceptance Affordable treatment Normal life No punishment punishment Social REJECTION EXPENSIVE treatment MISERABLE life
  52. 52. ADVANTAGES OF SEMANTIC DIFFERENTIAL SCALE • It is a convenient method to assess the beliefs, attitudes and values in quantitative form. • Easy to administer. • Provides reasonable valid and reliable quantitative data.
  53. 53. DISADVANTAGES OF SEMANTIC DIFFERENTIIAL SCALE • Lack of standardization of the tool. • Time consuming to find the appropriate adjective pairs.
  55. 55. VISUAL ANALOGUE SCALE • Visual "Analogue" Scale, is a psychometric response scale that is used to measure the intensity of certain sensations and feelings, such as pain, discomfort, anxiety, quality of sleep, severity of clinical symptoms, functional ability and attitude towards environmental conditions. • This has 10 cm lines and the ends marks semantic opposites. (alert-drowsy)
  56. 56. DEFINITION • VAS is a tool that is used to assist a person in rating the intensity of certain feelings and sensations. • The VAS is a bipolar scale used to determine the degree of stimuli a patient experiences. One side of the scale expresses the absence of stimuli, while the other expresses the presence of stimuli.
  58. 58. DEFINITION The word observation is derived from Latin word ‘observere’ which means ‘to notice’. Observation is a technique for collecting data or acquiring information through occurrences that can be observed through senses with or without mechanical devices. It is a two part process to collect data for study that includes an observer (someone who is observing) and the observed (there is something to observe).
  59. 59. USES OF OBSERVATION METHOD • To understand an ongoing process or situation. • To gather data on individual behaviours or interactions between peoples. • To know about a physical settings. • Data collection where other methods are not possible.
  60. 60. Types of observation  Structured Observation Un-structured Observation Participant Observation  Non participant Observation
  61. 61. Structured observations In this methods, researcher prepares a structured or semi-structured tool in advance to observe the phenonmenon under study. This helps researchers to be on track while carrying out an observation as well as analysis of data collected during this method of observation remains easy. • Check list • Rating scale • Category system
  62. 62. UNSTRUCTURED OBSERVATIONS This method is generally used in qualitative studies, where observation is made with minimally structured . It is used for complete and nonspecific observation of phenomenon, which is very well known by the researcher. • Log and field notes • Anecdotes • Field dairy • Video recording
  63. 63. PARTICIPANT OBSERVATION Historically, field and ethnographically researches have been associated most strongly with participant observations, where observer may live or work in field and actively participated in ongoing activities for an extended periods. • Log books • Fields notes • Field diary • Tape • Video recording
  64. 64. NON-PARTICIPANT OBSERVATION • In this type of observation the observer works as an eavesdropper, where an attempt is made to observe peoples without interacting with them. • In this techniques the observer is not a participant in the setting but is merely viewing the situations. Peoples are observed without their knowledge that they are being observed.
  65. 65. S.NO. CATEGORIES OBSERVATION METHOD 1. NARRATIVE OBSERVATION  Field notes  Anecdotes 2. Sample Observation  Rating Scales  Checklists  Event sampling  Time sampling 3. Technology assisted observation  Photographs  CCTV/ Audiotapes/ Videography
  66. 66. ADVANTAGES • It provides direct, real-time information on ongoing and unfolding behavior, process, situation or event. • It facilitates access to people and situation where questionnaires and interviews are impossible or inappropriate to use. • Data collected is accurate and reliable. • It provides access to people in real life situation. • It improves precision of research results. • Researcher gets current information.
  67. 67. DISADVANTAGES • Hawthrone effect • Time consuming & expensive • Does not enhance the clear cut understanding of why people behave as they do.
  68. 68. FIELD NOTES • Field note is a qualitative notes of an observation made by a researcher in a research setting, which includes descriptive and reflective narrations of the observed behaviour, event, place or person. It may even included sketches, drawing and diagrams. • Descriptive information is factual data that is being recorded. Includes time and date, physical setting, social environment, descriptions of the subjects being studied and their roles in the setting, and the impact that the observer may have had on the environment.
  69. 69. ANECDOTES • It is a brief, non-judgemental written record of an observed incident. Anecdotes are record of what, when, where, how event happened and what was said and done. • An anecdotal record is a short, objective, descriptive summary of one event or incident writing down after the event has taken place.
  70. 70. DISADVANTAGES • It is prone to bias because of halo effect, error of leniency, or error of severity. • If the subjects know that they are being observed, their behavior or practices will not be natural. (Hawthorne effect) • In covert observation there are ethical dilemmas, on the other hand overt observation affects the validity. • There is potential for misinterpretation. • Lack of control over events and circumstances during observation. • It requires trained personnel. RATING SCALE
  71. 71. RATING SCALE • Rating is the term used to express the opinion or judgement regarding some performance of a person, objects, situations or character. • Rating scale is a tool in which the one person simply checks of another person’s level of performance. • Rating scale could be three point, five point, seven points or more points.
  72. 72. Graphic Rating Scale Descriptive Rating Scale Numerical Rating Scale Comparative Rating Scale TYPES OF RATING SCALE
  73. 73. GRAPHIC RATING SCALE • The graphic rating scale is the simplest and most popular method for appraising performance. In this scale, the performance is printed horizontally at various points from lowest to highest. It included the numerical points on the scale. • Likert Scale is a popular graphic rating scale. EXAMPLE: To what extent staff nurse participates in clinical conference? 1 2 3 4 5
  74. 74. DESCRIPTIVE RATING SCALE • This types of rating scale does not uses number but divide the assessment into series of verbal phrases to indicate the level of performances. Examples: Judge the level of performance of nursing personnel in medical ICU Nursing personnel in a ward Level of clinical performance Very active active Moderately active passive Kiran Tara Jasveen karan
  75. 75. NUMERICAL RATING SCALE • In these scale, each statement is generally assigned a numerical score ranging from 1-10, or even more. It divide the evaluation criteria into a fixed number of points. Visual Analog Scale or a Semantic Differential Scale can be presented using a numerical rating scale.
  76. 76. COMPARATIVE RATING SCALE • In this type of rating scale, the researcher makes a judgement about an attribute of a person by comparing it with that of a similar another person.
  77. 77. ADVANTAGES OF RATING SCALES: • It can be used for large number of subjects. • Easy to administer and score. • Efficient and economical in terms of time and money. • Helps to reduce unreliability. • It is used to evaluate performance and skills.
  78. 78. DISADVANTAGES OF RATING SCALE • Difficult to fix up rating about many aspects of an individual. • Misuse can result in decrease in objectivity.
  79. 79. DISADVANTAGES • It is prone to bias because of halo effect, error of leniency, or error of severity. • If the subjects know that they are being observed, their behavior or practices will not be natural. (Hawthorne effect) • In covert observation there are ethical dilemmas, on the other hand overt observation affects the validity. • There is potential for misinterpretation. • Lack of control over events and circumstances during observation. • It requires trained personnel. CHECK LIST
  80. 80. CHECK LIST • A checklist is a simple device consisting of a prepared list of items, which are thought by the researcher to be relevant to the problem, which is being studied. The checklist consists of a list of items with a place to check or mark yes or no. • A checklist is a list of all the things that you need to do, information that you want to find out, or things that you need to take somewhere, which you make in order to ensure that you do not forget anything.
  81. 81. CHARACTERSTICS OF CHECKLISTS • Observe one respondents at one time. • Use only carefully prepared checklist to avoid more complex traits. • The observer should be trained how to observe, what to observe, and how to record the observed behavior.
  82. 82. Construction of checklist • Express each item in a clear, simple language. • The list of items in the checklist may be continuous or divided into groups of related items. • Avoid negative statements whenever possible. • Ensure that each items has clear responses: yes or no. true or false. • Review the items independently.
  83. 83. PROCEDURALCHECKLISTFORHANDWASHING S.NO. STEPS/ TASK 1 2 3 4 5 1 Remove rings, bracelets, and watch. 2 Wet hands in clean running water. Applies soap. 3 Vigorously rub hands together in following manner  Palms, fingers and web spaces 4  Back of hands 5  Fingers and knuckles 6  Thumbs 7  Fingertips and creases 8  Wrist and forearm up to the elbow 9 Thoroughly rinse hands in clean running water. 10 Dry hands using clean personal towel, paper towel, or allows to air dry .
  84. 84. ADVANTAGES OF CHECKLISTS • They can be developed very easily, quickly and are relatively less expensive. • Their design can be highly specific and adequate. • Checklist reduces the chances of error in observation. • It is useful to obtain a large amount of data. • It Saves time. • It is useful in evaluating learning activities. • It helps in evaluating procedural work. • It has objectivity in evaluating characteristics.
  85. 85. DISADVANTAGES OF CHECK LIST • Does not indicate quality of performance, so usefulness of checklist is limited. • It is very easy for certain important items to be omitted in a checklist.
  87. 87. BIOPHYSIOLOGICAL METHODS • Bio-physiologic method involves the collection of bio- physiological data from subjects by using the specialized equipments to determine biological and physical status of subjects.
  88. 88. PURPOSES OF BIO-PHYSIOLOGIC METHODS • To study basic physiologic process • To study physiologic outcome to nursing care • To evaluation nursing intervention • To study correlation of physiologic functioning with patients problems.
  90. 90. IN- VIVO BIOPHYSIOLOGIC METHOD • In this method, measurement are directly performed over the organism or study subjects by using specialized instruments or equipments. Example • Measurement of the BP by using sphygmomanometer. • Cardiac conduction using ECG machine • Temperature using thermometer • Oxygen saturation using pulse oximeter
  91. 91. • In-vivo measuring instrument system involves the following 6 components 1. Stimulus 2. Subject 3. Sensory equipment (Transducers & electrodes) 4. Signal conditioning (amplifiers and signals processors) 5. Display equipment 6. Recording equipment (Physiologic measurement are good examples of in-vivo bio- physiologic measurement TPR, BP)
  92. 92. IN- VITRO BIOPHYSIOLOGIC METHOD • It is the measurement of the bio-physiologic attributes of the subjects, which is carried out through collection of sample of data related to physical, bio-chemical, microbiologic, pathologic and anatomic status by using some technical instruments and by sending them to laboratory for their analysis and interpretation. • In-vitro bio-physiologic methods, measurements are carried out outside the organism by using specialized equipments.
  93. 93. ADVANTAGES OF BIOPHYSIOLOGIC METHODS • Bio-physiologic measures are relatively more accurate and errorless. • Provide valid measures for targeted variables. • Easy access to most of the instruments.
  94. 94. DISADVANTAGES OF BIOPHYSIOLOGIC METHODS • Some of the instruments are very expensive. • Requires training, knowledge and experiences. • The results produced by the bio-physiologic measurement instruments may be affected by the environments. • Fear and anxiety among participants. • Some bio-physiologic methods may have harmful effect on participants.
  96. 96. Projective techniques
  97. 97. DEFINITION • Projective techniques are methods for measuring psychologic attributes (value, attitudes and personality) by providing respondents with unstructured stimuli to which they respond. • Projective test is a type of psychological test that assesses a person’s thinking pattern, observational ability, feelings and attitudes on the basis of responses to ambiguous test materials.
  98. 98. ASSOCIATION TECHNIQUE • A techniques in which the respondents is presented with a stimulus and asked to response with the first words comes in mind. Techniques- • Word association
  99. 99. CONSTRUCTION TECHNIQUES • The subject is required to produce or construct something at direction, usually a story or picture.
  100. 100. THEMATIC APPRECITATION TEST • The Thematic Apperception test is a type of projective test that involves describing ambiguous scenes. Its evaluate a person's patterns of thought, attitudes, observational capacity, and emotional responses to ambiguous test materials. • The TAT includes 32 picture cards depicting a variety of scenes depicting characters that may include men, women, children, and human subjects altogether. The scenes explore a number of themes including those related to sexuality, aggression, failure, success, and relationships. Respondents are asked what they think the picture represents.
  101. 101. • The Rosenzweig Picture Frustration test consists of 24 cartoon pictures, each portraying two persons in a frustrating situation. Each picture contains two "speech balloons," a filled one for the "frustrator" or antagonist, and a blank one for the frustrated person, or protagonist. The subject is asked to fill in the blank balloon with his or her response to the situation, and the responses are scored in relation to a number of psychological defense mechanisms. ROSENZWEIG TEST
  102. 102. RORSCHACH TEST • The Rorschach inkblot test is a type of projective psychological test created in 1921 by a Swiss psychologist named Hermann Rorschach. It utilized to assess personality and emotional functioning.
  103. 103. • The Rorschach test consists of 10 inkblot images, some of which are black, white, or gray and some of which are color. • The test shows each of the ten cards to the respondent. During the test, the subject is provided with each of the ten cards, one by one. • The subject is then asked to describe what he or she thinks the card looks like. Test-takers are allowed to hold the cards in any position they may want, whether it is upside down or sideways. • The respondents are free to interpret the image however they want. Once the subject has provided a response, the psychologist will then ask additional questions to get the subject to further elaborate on his or her initial impressions.
  104. 104. HOLTZMAN INKBLOT TEST (HIT) • The Holtzman Inkblot Technique (HIT), also known as the Holtman Inkblot Test, is an inkplot test aimed at detecting personality. • It was first introduced in 1961 as a projective personality test similar to the Rorschach. • The Holtzman Inkblot Test was invented as an attempt to address some controversial issues surrounding the Rorschach Inkblot Test.
  105. 105. TOMKINS-HORN PICTURE ARRANGEMENT TEST • This test is designed for group administration with 25 plates, each containing three sketches that may be arranged in different ways to portray sequences, which participants consider reasonable. Write a sentence for each of three pictures to tell a story.
  106. 106. COMPLETION TECHNIQUES Completion projective technique supply the subjects with stimulus that is incomplete and the subject is required to complete it as he/she wishes.
  107. 107. • Sentences completion test
  108. 108. • Story completion test
  109. 109. EXPRESSIVE TECHNIQUE • This technique generally concentrate on the way in which something is constructed by the subjects, as against on what it represents.
  110. 110. ORDERING CHOICE • This type of projective techniques is most frequently used in quantitative researches. This techniques is generally used informally
  111. 111. MISCELLANEOUS TYPE • Drawing a picture • Creating families • Using fantasy and day dreams • Clay modelling
  114. 114. Q-Sorts
  115. 115. Q-Sorts • Q-Sorts was developed in 1930 by a British physicist- psychologist William Stephenson. The idea behind the development of this methods was to inquire into the subjectivity of human mind.
  116. 116. DEFINITION • Q-Sorts are the powerful tools in which the participants are presented with card arrangement. In this techniques, participants are provided pre-written cards with words, phrases or statements and are asked to arrange theses cards in an order along with specific bipolar dimension. There are approximately 60-100 such cards that can be sorted out in 9-11 piles with few numbers of cards placed in each piles.
  117. 117. ADVANTAGES OF Q-SORTS • Provide in depth study of small sample populations. • No needs of the participants to be randomly selected.
  118. 118. DISADVANTAGES OF Q-SORTS • It takes much time. • Not cost effective • Small sample can be studied. • Can not be use to test hypothesis.
  119. 119. VIGNETTES
  120. 120. VIGNETTES • In order to explore people’s beliefs, perceptions and meaning about some particular situations vignettes as a valuable techniques. • The vignette techniques is a method that can elicit perceptions, opinions, beliefs and attitudes from responses or comments to stories depicting scenarios and situations. • Vignettes are short scenarios in written or pictorial form, intended to elicit responses to typical scenarios.
  121. 121. USES OF VIGNETTES • Tapping general beliefs and attitudes. • Sensitive topics exploration • Comparisons of perceptions of disparate groups • Used in focus group discussions.
  122. 122. ADVANTAGES OF VIGNETTES • Allow face to face contacts with respondents. • Give opportunity to explore topics in depth. • Make it easy for respondents to reply to the concerned topics. • Provide detailed data.
  123. 123. DISADVANTAGES • Cover limited sample size. • Volume of information can be difficult to record, very large.
  125. 125. DATA COLLECTION STEPS Defining the data to be collected Selecting appropriate method of data collection Selecting or developing data collection instruments Try out of data collection instruments and procedure Developing data collection supportive forms and procedure Training of data collectors Inform local authority for data collection and obtain due permissions Data collection and data management
  127. 127. DEFINITION • Validity of an instruments refers to the degree to which an instruments measures what it is supposed to measuring. • Validity is the appropriateness, completeness and usefulness of an attribute measuring research instruments.
  128. 128. RELIABILITY
  129. 129. RELIABILITY • Reliability is the degree of consistency with which attributes or variables are measured by an instruments. • Reliability pertains to the consistency of a measures. A test is thought to be reliable if we get the same result in a repeated manner. • Reliability is defined as the ability of an instruments to create reproducible results. A tool can only be considered reliable if it measures an attribute with similar result on repeated use.
  130. 130. MEASURING OF RELIABILITY • Stability • Internal consistency • equivalence
  131. 131. STABILITY • The stability of reliability means research instruments provide same results when used consecutively for two or more times. • Statistical calculation (Test-retest Method) It is used for questionnaire, observation, check list, rating scales, and physiological measurements tools. • Interpretation of results (-1.00 through 0.0 and +1.00) +1.00 score indicate perfect reliability 0 score indicated no reliability Above 0.70 indicate acceptable level of reliability
  132. 132. INTERNAL CONSISTENCY • Internal consistency also known as homogeneity. It ensures that all the sub parts of a research instruments measure the same characteristics. • A research tool can only be considered internally consistent if all the subparts of the tool are measuring the same characteristics of the phenomena. • Statistical calculation (Split-Half Method)
  133. 133. EQUIVALENCE • This is also known as inter rater or inter observer reliability. Which is estimated by the administration of tool to observe a single event simultaneously and independently by two or more trained observers. Number of agreements No. of agreements + no. of disagreements r =
