- 2. Meaning of research • A careful investigation or inquiry specially through search for new facts in any fields of knowledge. [email protected]
- 3. Definitions of Research • The main goal of research is the gathering and interpreting of information to answer questions (Hyllegard, Mood, and Morrow, 1996). • Research is a systematic attempt to provide answers to questions (Tuckman, 1999). • Research may be defined as the systematic and objective analysis and recording of controlled observations that may lead to the development of generalizations, principles, or theories, resulting in prediction and possible control of events (Best and Kahn, 1998). • Research is a systematic way of asking questions, a systematic method of inquiry (Drew, Hardman, and Hart, 1996).

- 4. Objectives • To gain familiarity with a phenomenon or to achieve new insights into it - Exploratory • To portray accurately the characteristics of a particular individual, situation or group- Descriptive • To determine the frequency with which something occurs-Diagnostic • To test a hypothesis of a causal relationship- Hypothesis testing [email protected]
- 5. Motivation in research • Desire to – Get a research degree – Face challenges in solving unsolved problems – Get intellectual joy of doing some creative work – Be of service to society – Desire to get respectability [email protected]
- 6. Structure of Research begin with broad questions narrow down, focus in operationalize OBSERVE analyze data reach conclusions generalize back to questions The "hourglass" notion of research [email protected]
- 7. Variables • variable… – any observation that can take on different values • attribute… – a specific value on a variable [email protected]
- 9. Examples Variable Attribute age 18, 19, 20, etc... [email protected]
- 11. Examples Variable Attribute Gender or sex Male, female [email protected]
- 13. Examples Variable Attribute satisfaction 1 = very satisfied 2 = satisfied 3= somewhat satisfied 4 = not satisfied 5 = not satisfied at all [email protected]
- 14. Types of Variables • independent variable (IV)… – what you (or nature) manipulates in some way • dependent variable (DV)… – what you presume to be influenced by the IV [email protected]
- 15. Examples IV DV exercise participation health status attitude social support intervention [email protected]
- 16. Research Process • Define research problem • Review of Literature – Conceptual – Empirical • Formulate hypothesis • Design research – Exploratory – Conclusive – Diagnostic – Experimental – Causal • Sampling [email protected]
- 17. • Collect data – Observation – Personal interview – Telephonic interview – Mailing questionnaires – Through schedules • Analyze data (Test hypothesis if any) – Editing – Coding – Tabulating etc. performed first • Interpret and report [email protected]
- 18. Research Problem • Statement of the research problem in a general way • Understanding the nature of the problem • Surveying the available literature • Developing the ideas through discussions • Rephrasing the research problem [email protected]
- 19. – “Why is productivity of Japan so much higher than India”? Ambiguities – What sort of productivity? – What industries ? – Time period? – Better way to define the problem would be: – “What factors were responsible for higher productivity of Japan’s manufacturing industries during the decade 1971 to 1980 relative to India’s manufacturing industries”? – “To what extent did labour productivity in 1971 to 1980 in Japan exceed that of India in respect of 15 selected manufacturing industries? What factors were responsible for the productivity differentials between the two countries by industries” [email protected]
- 20. Hypotheses • hypothesis… – a specific statement of prediction • types of hypotheses – alternative vs. null – one-tailed vs. two-tailed [email protected]
- 21. Hypothesis Formulation --- Formulate a hypothesis --- Frame the hypothesis in a format that is testable --- Test the hypothesis 21 [email protected]
- 22. Formulating a Hypothesis • Hypothesis: – A belief or prediction of the eventual outcome of the research – A concrete, specific statement about the relationships between phenomena – 2 types of hypotheses: • Null hypothesis (HO) – All is equal; no differences exist • Alternative (research) hypothesis (HA) – Usually specific and opposite to the null [email protected]
- 23. Hypotheses hypothesis there is a relationship between age and exercise participation HA there is a relationship HO there is no relationship this is a two-tailed hypothesis as no direction is predicted [email protected]
- 24. Hypotheses hypothesis an incentive program will increase exercise participation HA participation will increase HO participation will not increase or will decrease this is a one-tailed hypothesis as a specific direction is predicted [email protected]
- 25. Research Design • A frame work for conducting the research project. • Outlines how the research project will be conducted. • Details the procedures necessary for obtaining the information needed to structure and/or solve research projects. • Guides the data collection ,analysis and report presentation [email protected]
- 26. Research Design • What is the study about? • Why is the study being made? • Where will the study be carried out? • What type of data will be required? • Where can the required data be found? • What periods of time will the study include? • What will be the sample design? • What techniques of data collection will be used? • How will the data be analyzed? • In what style will the report be presented? [email protected]
- 27. Sampling Designs • Sampling Design Process – Define target population – Determine sampling frame • a list of the items or people forming a population from which a sample is taken. – Select sampling technique(s) – Determine the sample size – Execute the sampling process [email protected]
- 28. Sampling techniques • Non probability • Convenience • Judgmental • Quota • Snowball • Probability • SRM • Systematic • Stratified • Cluster [email protected]
- 30. Attitude Measurement • Attitude – an expression of favour or disfavour toward a person, place, thing or event • Attitude can be formed from a person’s past and present • Attitude is also measurable and changeable as well as influencing the person’s behaviour.
- 31. I believe that chocolate packaging is important
- 32. Methods of Measuring Attitudes • Rating – Likert Scale – carefully constructed attitudinal measure which asks people for their agreement with a statement – Example: Please rate each of the following, on a scale from 1 to 10, with 1 being least important and 10 being most important…
- 33. • Multiple Choice Questions (MCQ)

- 38. Forced Choice • Does not allow the respondent to offer no opinion, which is different than a neutral opinion
- 39. Unforced Choice • Allows respondents to opt out of providing an opinion.
- 40. • Ranking – Rank choices from most important to least important • Example: Of the following 10 items please rank them in order of importance, with 1 being least important and 10 being most important.
- 41. Questionnaire • A set of questions designed to generate the data necessary for accomplishing a research project's objectives
- 42. Complexity of Questionnaire Design Do you consider that the many research texts are adequate for most of your business majors at the undergraduate level ? _____ Yes ____ No If no; briefly, why not? Is your friend sociable and lovable? _____ Yes ____ No If no; briefly, why not?
- 43. Can the Respondent Answer the Question? (Cont’d) • Consider the following question taken from a questionnaire used by a marketing research firm in conducting a face-to-face survey of female household heads – How much has your family spent in the last 12 months on cookware? $ _______
- 44. Can the Respondent Answer the Question? • In your opinion, how many students in your marketing courses will become potentially successful marketing managers? Ten percent ______ Twenty percent______ Thirty percent ______ ______percent ______
- 45. • Questionnaire quality and design criteria – What should be asked? – How should questions be phrased? – In what sequence the questions be arranged? – What questionnaire layout will best serve the research objectives? – How should the questionnaire be pretested? – Does the questionnaire need to be revised?
- 46. Questionnaire General Format • Self-administered (by mail or personal contact) • In person (face-to-face) • Telephone interviews
- 47. Question Form • Nonstructured questions – Open-ended • Structured questions – Fixed-response
- 48. Nonstructured Questions • Consider the following illustrative questions How old are you?___________________ What do you like most about owning your own home? _____________ Will you please describe your thoughts about a person who shoplifts items from a grocery store to keep from going hungry? _________________________________________ _________________________________________ ____

- 55. . Response Category • The response choices are collectively exhaustive but not mutually exclusive • On the average, how many cans of cola do you drink per week ____0 to 3 cans ____3 to 6 cans ____More than 6 cans • Changing the 3 in the second category to a 4 will make the response choices mutually exclusive
- 56. Writing a Questionnaire for International Markets • Caution – Use of the same word can have different meanings in different cultures • Word Equivalence – In Japan, China and non-English speaking European countries • “Very Satisfied” means “Somewhat Satisfied” • “Very Satisfied” should be replaced by “Totally Satisfied”
- 57. Will the Respondent Answer the Question? • Questions about personal financial matters or sexual behavior are examples of sensitive questions • Words used in the questions should not be ambiguous to the respondents
- 58. Double-Barreled Questions • Suppose the following question is to be used in conducting a survey of the general public – Do you feel firms today are concerned about their employees and customers? _____ Yes _____ No • A “no” response can be interpreted three different ways – The respondent feels firms are concerned about neither employees nor customers – The respondent feels firms are concerned about employees but not customers – The respondent feels firms are not concerned about employees although they are concerned about customers
- 59. Avoiding Double-Barreled Questions • This revision is usually accomplished by breaking one question into several questions • Thus our illustrative question can be reworded as two separate questions – Do you feel firms today are concerned about their employees? ___ Yes ___ No – Do you feel firms today are concerned about their customers? ___ Yes ___ No

- 68. Univariate, bivariate and multivariate data • Types of data based on number of variables – Univariate :Analysis are made only based on one variable – Bivariate: Two variables – Multivariate :Two or more variables
- 69. Hypothesis Testing Procedures Hypothesis Testing Procedures Nonparametric Parametric Z Test Kruskal-Wallis H-Test Wilcoxon Rank Sum Test t Test One-Way ANOVA Many More Tests Exist!
- 70. Hypothesis testing • What u normally do – If calculated value is less than the table value- hypothesis accepted – If calculated value is more than the table value- hypothesis rejected • How you do in SPSS? – If the p value is > .05 – The result is insignificant – If the p value is < .05 – The result is significant
- 71. Chi square tests • Chi-square is a statistical test commonly used to compare observed data with data we would expect to obtain according to a specific hypothesis. • The chi-square test is always testing what scientists call the null hypothesis, which states that there is no significant difference between the expected and observed result. • We want to compare our observed data to what we expect to see. Due to chance? Due to association?
- 72. Assumptions: • Independent observations • A sample size of at least 10 • Random sampling • All observations must be used • For the test to be accurate, the expected frequency should be at least 5
- 73. Conducting Chi-Square Analysis 1) Make a hypothesis based on your basic biological question 2) Determine the expected frequencies 3) Create a table with observed frequencies, expected frequencies, and chi-square values using the formula: (O-E)2 E 4) Find the degrees of freedom: (c-1)(r-1) 5) Find the chi-square statistic in the Chi-Square Distribution table 6) If chi-square statistic > your calculated chi-square value, you do not reject your null hypothesis and vice versa.
