Learning Objectives

Understand . . . The terminology used by professional researchers employing scientific thinking. What you need to formulate a solid research hypothesis.

The need for sound reasoning to enhance research results.

Research Thought Leaders

“Thought leaders, academics, business authors from the increasingly merging worlds of psychology, philosophy, economics, trends, semiotics are powerful forces, that have the ability to capture the imagination and attention at the highest level of business. Research needs to define itself more broadly, embrace the most exciting thinkers into our fold. We need to infuse our thinking with that of related fields.”

Edward Appleton, senior European consumer insights manager,

Avery Dennison

Moderating Variables (MV)

The introduction of a four-day week (IV) will lead to higher productivity (DV), especially among younger workers (MV)

The switch to commission from a salary compensation system (IV) will lead to increased sales (DV) per worker, especially more experienced workers (MV).

The loss of mining jobs (IV) leads to acceptance of higher-risk behaviors to earn a family-supporting income (DV) – particularly among those with a limited education (MV).

Page 15: Chapter 3

3-15

Extraneous Variables (EV)

With new customers (EV-control), a switch to commission from a salary compensation system (IV) will lead to increased sales productivity (DV) per worker, especially among younger workers (MV).

Among residents with less than a high school education (EV-control), the loss of jobs (IV) leads to high-risk behaviors (DV), especially due to the proximity of the firing range (MV).

Page 16: Chapter 3

3-16

Intervening Variables (IVV)

• The switch to a commission compensation system (IV) will lead to higher sales (DV) by increasing overall compensation (IVV).

• A promotion campaign (IV) will increase savings activity (DV), especially when free prizes are offered (MV), but chiefly among smaller savers (EV-control). The results come from enhancing the motivation to save (IVV).

Descriptive Hypothesis Formats

Descriptive Hypothesis In Detroit, our

potato chip

market share stands at

13.7%. American cities are experiencing budget difficulties.

Research Question What is the market share for our potato chips in Detroit? Are American cities experiencing budget difficulties?

Page 19: Chapter 3

3-19

Relational Hypotheses Formats

Correlational Young women (under 35) purchase fewer units of our product than

women who are older than 35.

The number of suits sold varies directly with the level of the business cycle.

Causal An increase in family income leads to an increase in the percentage of

income saved. Loyalty to a grocery store increases the probability of

purchasing that store’s private brand products.

Inductive Reasoning

Why didn’t sales increase during our promotional event? Regional retailers did not have sufficient

stock to fill customer requests during the promotional period

A strike by employees prevented stock from arriving in time for promotion to be effective

A hurricane closed retail outlets in the region for 10 days during the promotion

Snapshot: Politicized Definitions

The National Academies advises on scientific issues.

Created voluntary guidelines for embryonic stem cell research.

Comprehensive definition of terms accepted by every researcher.

Volatile political issue = no nationwide guidelines

Politicians fill the void with own definitions to exploit personal agenda.

“People usually experience true intuition when they are under severe time pressureor in a situation of information overload or acute danger, where conscious analysis of the situation may be difficult or impossible.”

Pull Quote: Research Thought Leaders

“Brand communities play a pivotal role for a brand connecting with its consumers, and as one of our Never Ending Friending focus group respondent notes: “I want brands to be my friends,” which means that consumers would like to have common ideas, conversations and benefits delivered to them on their own terms.”

Formulating a Hypothesis

Wal-Mart recently decided not to share its unit sales information with IRI, a large syndicated research distributor. After studying the data, Wal-Mart didn’t think it was getting enough value from competitor information in the syndicate. What hypothesis might have driven its research?
