Information
• Reduces uncertainty
• Helps focus decision making

Types Of Research
• Exploratory
• Descriptive
• Causal

Exploratory Research
• Initial research conducted to clarify and define the nature of a problem
• Does not provide conclusive evidence
• Subsequent research expected
![Page 8: ch04](https://reader036.vdocuments.us/reader036/viewer/2022062520/55cf85e0550346484b9253bb/html5/thumbnails/8.jpg)
Descriptive Research
• Describes characteristics of a population or phenomenon
• Some understanding of the nature of the problem
![Page 9: ch04](https://reader036.vdocuments.us/reader036/viewer/2022062520/55cf85e0550346484b9253bb/html5/thumbnails/9.jpg)

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
![Page 11: ch04](https://reader036.vdocuments.us/reader036/viewer/2022062520/55cf85e0550346484b9253bb/html5/thumbnails/11.jpg)
Descriptive Research Example
• Men’s fragrance market
• 1/3 size of women’s fragrance market
• But growing at a faster pace
• Women buy 80 % of men’s fragrances
![Page 12: ch04](https://reader036.vdocuments.us/reader036/viewer/2022062520/55cf85e0550346484b9253bb/html5/thumbnails/12.jpg)
Causal Research
• Conducted to identify cause and effect relationships
![Page 13: ch04](https://reader036.vdocuments.us/reader036/viewer/2022062520/55cf85e0550346484b9253bb/html5/thumbnails/13.jpg)
Identifying Causality
• A causal relationship is impossible to prove.
• Evidence of causality:– 1. The appropriate causal order of events– 2. Concomitant variation--two
phenomena vary together– 3. An absence of alternative plausible
explanations

Research Stages
• Cyclical process - conclusions generate new ideas
• Stages can overlap chronologically
• Stages are functionally interrelated– Forward linkages– Backward linkages

Stages In The Research Process
• Problem Discovery and Problem Definition
• Research Design
• Sampling
• Data Gathering
• Data Processing and Analysis
• Conclusions And Report
![Page 20: ch04](https://reader036.vdocuments.us/reader036/viewer/2022062520/55cf85e0550346484b9253bb/html5/thumbnails/20.jpg)
Problem Discovery And Definition
• First step
• Problem, opportunity, or monitor operations
• Discovery before definition
• Problem means management problem
![Page 21: ch04](https://reader036.vdocuments.us/reader036/viewer/2022062520/55cf85e0550346484b9253bb/html5/thumbnails/21.jpg)

solution”

Hypothesis
• A statement
• that can be refuted
• by empirical data
![Page 24: ch04](https://reader036.vdocuments.us/reader036/viewer/2022062520/55cf85e0550346484b9253bb/html5/thumbnails/24.jpg)

Exploratory Research Techniques Two Examples
• Secondary data (historical data)– Previously collected– Census of population– Literature survey
• Pilot study– A number of diverse techniques
![Page 27: ch04](https://reader036.vdocuments.us/reader036/viewer/2022062520/55cf85e0550346484b9253bb/html5/thumbnails/27.jpg)
