Information
• Reduces uncertainty
• Helps focus decision making
![Page 3: Chapter 4 Modified](https://reader033.fdocuments.us/reader033/viewer/2022051017/55cf9a10550346d033a04f8f/html5/thumbnails/3.jpg)

Exploratory Research
• Initial research conducted to clarify and define the nature of a problem
• Does not provide conclusive evidence
• Subsequent research expected
![Page 7: Chapter 4 Modified](https://reader033.fdocuments.us/reader033/viewer/2022051017/55cf9a10550346d033a04f8f/html5/thumbnails/7.jpg)
Descriptive Research
• Describes characteristics of a population or phenomenon
• Some understanding of the nature of the problem
![Page 8: Chapter 4 Modified](https://reader033.fdocuments.us/reader033/viewer/2022051017/55cf9a10550346d033a04f8f/html5/thumbnails/8.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 9: Chapter 4 Modified](https://reader033.fdocuments.us/reader033/viewer/2022051017/55cf9a10550346d033a04f8f/html5/thumbnails/9.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

Causal Research
• Conducted to identify cause and effect relationships
![Page 11: Chapter 4 Modified](https://reader033.fdocuments.us/reader033/viewer/2022051017/55cf9a10550346d033a04f8f/html5/thumbnails/11.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
![Page 12: Chapter 4 Modified](https://reader033.fdocuments.us/reader033/viewer/2022051017/55cf9a10550346d033a04f8f/html5/thumbnails/12.jpg)
Exercise
For each of the situations below, decide whether the research should be exploratory, descriptive, or causal?
1. Establishing the functional relationship between advertising and sales
2. Investigating reactions to the idea of a new method of defense budgeting
3. Identifying target market demographics for a shopping center4. Estimating prices for IBM stock two years in the future5. Learning how many organizations are actively involved in just-
in-time production6. Learning the extent of job satisfaction in a company.

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
