The document outlines the stages of the research process, including problem discovery, research design, sampling, data gathering, processing, analysis, and reporting. It emphasizes the significance of defining research problems and objectives, distinguishing between management decision problems and research problems, and formulating research questions and hypotheses. Examples are provided to illustrate how to compare demographic profiles and test statistical relationships.

- 4. Problem Definition, Objectives, and Research Questions If you do not know where you are going, any road will take you there.
- 5. “The formulation of the problem is often more essential than its solution” -Albert Einstein
- 6. Two Types of Problems Management Decision Problem What decision makers need to do Sales are on the decline Customer base is aging and younger consumers prefer competitor’s brands Research Problem Specifies information needed to address managerial problems & how it can be obtained
- 7. MDP Action Oriented Focus on symptoms Should new product be introduced Should advertisement be changed Should price be increased Research Problem Information oriented Focus on underlying causes Determine consumer preferences Determine effectiveness of current ad. Price elasticity of demand
- 8. Research Objectives Research objectives address information gaps that must be closed so the manager solves the marketing management problem Each research objective must be precise, detailed, clear, and operational Example: “Compare the demographic profiles of AT&T buyers to nonbuyers using age, sex, education, and annual family income.”
- 9. Research Questions A research question is the researchers’ paraphrase of the research objective(s) in the form of a question. Example: “Are AT&T’s non-buyers different demographically from AT&T’s buyers? Or better yet: “Are AT&T’s non-buyers younger than AT&T’s buyers?” Specific questions are better
- 10. Research Hypotheses A hypothesis is an unproven proposition or supposition that tentatively explains certain facts or phenomena; a probable answer to a research question. Hypotheses are statements about the nature of the world. They are guesses. Example: “AT&T’s non-buyers are younger than AT&T’s buyers”
- 11. Research Hypotheses Null Hypothesis: Conservative statement about the status quo. It is what our research is set out to disprove. H0: AT&T non-buyers do not differ in age from AT&T buyers Alternative Hypothesis: A statement that states the opposite of the null hypothesis. HA: AT&T non-buyers are younger than AT&T buyers
