Chapter 4: The Business Research Process: An Overview
Decision Making Information reduces uncertainty -It helps focus decision making Certainty Uncertainty Ambiguity
Types Of Research Exploratory Descriptive Causal Initial research conducted to clarify ambiguous situations or discover potential business opportunities Does not provide conclusive evidence Subsequent research expected Useful in new product development Descriptive Describes characteristics of a population or phenomenon (who, what, when, where, and how) Some understanding of the nature of the problem Useful in describing market segment Causal Conducted to identify cause and effect relationships
Degree of Problem Definition Exploratory Research Descriptive Research Causal Research (Unaware of Problem) (Aware of Problem) (Problem Clearly Defined) “Our sales are declining and “What kind of people are buying “Will buyers purchase more of we don’t know why.” our product? Who buys our our products in a new package? competitor’s product?” “Would people be interested “Which of two advertising in our new product idea?” “What features do buyers prefer campaigns is more effective?” in our product?” possible situation
Descriptive Research Example Weight Watchers average customer Woman about 40 years old Household income of about $50,000 At least some college education Trying to juggle children and a job
Identifying Causality Evidence of causality: 1. Temporal Sequence - the appropriate causal order of events – the cause must occur before the effect 2. Concomitant variation--two phenomena vary together systematically, i.e, when a change in the cause occurs, a change in the outcome also is observed . Correlation coefficient is used to represent concomitant variation. An absence of alternative plausible explanations 3. Non-spurious Association (eg. Icecream sales) Often Use Experiments in Causal Research
Uncertainty Influences The Type Of Research CAUSAL OR DESCRIPTIVE COMPLETELY CERTAIN ABSOLUTE AMBIGUITY EXPLORATORY
Stages of the Research Process P Defining Objectives Discovery and Definition ------- and so on Research Design Conclusions and Report Sampling Data Processing and Analysis Data Gathering
Research Stages Cyclical process - conclusions generate new ideas Stages can overlap chronologically Stages are functionally interrelated Forward linkages Backward linkages
Define objectives Selection of exploratory research technique Sample Design Define objectives Problem Discovery and Definition Sampling Selection of exploratory research technique Probability Nonprobability Secondary (historical) data Experience survey Pilot study Case study Collection of data (fieldwork) Data Gathering Data Processing and Analysis Editing and coding data Problem definition (statement of research objectives) Data processing Selection of basic research method Research Design Conclusions and Report Interpretation of findings Experiment Survey Observation Secondary Data Study Report Laboratory Field Interview Questionnaire
Stages In The Research Process Problem Discovery and Problem Definition Research Design Sampling Data Gathering Data Processing and Analysis Conclusions And Report
“The formulation of the problem is often more essential than its solution” Albert Einstein
Problem Discovery And Definition First and probably most important step Too often neglected leading to costly errors Provides direction for the project Problem, opportunity, or monitor operations Discovery before definition Must not mistake symptoms for problem
Exploratory Research Techniques Three Examples Secondary data (historical data) Previously collected for another purpose Literature survey Databases (e.g., www.census.gov) Pilot study A number of diverse techniques Focus Groups 6 to 10 people in group dynamics session
State the research questions and research objectives Hypothesis: A statement that can be refuted by empirical data
Research Design Master plan Specifies methods and procedures Framework for action
Basic Research Methods Surveys Interview Questionnaire Experiments control conditions so that one or more variables can be manipulated to test a hypothesis Field Laboratory Secondary data study Observation
Selecting a Sample Sample: subset SAMPLE of a larger population.
Sampling Who is to be sampled? How large a sample? How will sample units be selected? Probability Samples – every member of the population has a known, nonzero probability of being selected Nonprobability Samples
Data Gathering Stage Focus on error minimization Pretesting
Data Processing and Analysis Editing Checking the data collection forms for omissions, legibility and consistency Coding Rules for interpreting, categorizing and recording the data
Conclusions And Report Writing Effective communication of the research findings Usually includes making recommendations “What does this mean to management?”

Problem Discovery and Definition First step Problem, opportunity, or monitor operations Discovery before definition Problem means management problem
“The formulation of the problem is often more essential than its solution.” Albert Einstein
Problem Definition The indication of a specific business decision area that will be clarified by answering some research questions. Problems Mean Gap Business performance is worse than expected Actual business performance is less than possible Expected business performance is greater than possible business performance
Defining Problem Results in Clear Cut Research Objectives Symptom Detection Analysis of the Situation Exploratory Research (Optional) Problem Definition Statement of Research Objectives
The Process of Problem Definition Ascertain the decision maker’s objectives Determine unit of analysis Understand background of the problem Determine relevant variables Isolate/identify the problem, not the symptoms State research questions and objectives
Ascertain the Decision Maker’s Objectives Managerial goals expressed in measurable terms.
The Iceberg Principle The principle indicating that the dangerous part of many business problems is neither visible to nor understood by managers.
Understand the Background of the Problem Exercising judgment Situation analysis - The informal gathering of background information to familiarize researchers or managers with the decision area.
Isolate and Identify the Problems, Not the Symptoms Symptoms can be confusing
Symptoms Can Be Confusing Twenty-year-old neighborhood swimming association: Membership has been declining for years. New water park -residents prefer the expensive water park???? Demographic changes: Children have grown up
Problem Definition Organization Symptoms Based on Symptom True Problem Twenty-year-old neighborhood swimming association in a major city. Membership has been declining for years. New water park with wave pool and water slides moved into town a few years ago. Neighborhood residents prefer the expensive water park and have negative image of swimming pool. Demographic changes: Children in this 20-year-old neighborhood have grown up. Older residents no longer swim anywhere.

Determine the Unit of Analysis Individuals, households, organizations, etc. In many studies, the family rather than the individual is the appropriate unit of analysis.
Determine the Relevant Variable Anything that may assume different numerical values
Types of Variables Categorical Continuous Dependent Independent
Hypothesis An unproven proposition A possible solution to a problem Guess
State the research questions and research objectives
If you do not know where you are going, any road will take you there.
Broad research objectives Statement of business problem Exploratory research (optional) Specific Objective 1 Specific Objective 2 Specific Objective 3 Research Design Results
Research Proposal A written statement of the research design that includes a statement explaining the purpose of the study Detailed outline of procedures associated with a particular methodology Normally a schedule of costs and deadline is included
Basic Questions - Problem Definition What is the purpose of the study? How much is already known? Is additional background information necessary? What is to be measured? How? Can the data be made available? Should research be conducted? Can a hypothesis be formulated?
Basic Questions - Basic Research Design What types of questions need to be answered? Are descriptive or causal findings required? What is the source of the data?
Basic Questions - Basic Research Design Can objective answers be obtained by asking people? How quickly is the information needed? How should survey questions be worded? How should experimental manipulations be made?
Basic Questions - Selection of Sample Who or what is the source of the data? Can the target population be identified? Is a sample necessary? How accurate must the sample be?
