Business leaders rely on the work of marketing researchers to make decisions that will impact revenue
generation and the profitability of the company. The data analysis and interpretation phase of a marketing
research project is a critical process that is highly scrutinized for accuracy and validity. Marketing
researchers must take great care in analyzing data that will be interpreted and turned into information for
the purpose of solving the research problem, or capitalizing on an opportunity that was under study.

Means
• t-test: Utilizes t distribution
– Used when the sample size is smaller than 30, and
the standard deviation is unknown
• Formula to calculate the value of t
– Where,
1

1 2
– Mean of sample 1
– Mean of sample 2
– Standard error of the difference between the two means

Analysis of Variance (ANOVA)
• ANOVA: Determines whether three or more
means are statistically different from one
another
– Null hypothesis
µ1 = µ2 = µ3
• F-test: Statistically evaluates the differences
between the group means in ANOVA

Analysis of Variance (ANOVA) (continued)
• Follow-up test: Flags the means that are
statistically different from each other
– Performed after an ANOVA determines that there
are differences between means
• n-way ANOVA: Analyzes several independent
variables at the same time
– Interaction effect: Multiple independent variables
in an ANOVA acting together to affect dependent
variable means

Qualitative Data
Analysis

Learning Objectives
• Contrast qualitative and quantitative data
analyses
• Explain the steps in qualitative data analysis
• Describe the processes of categorizing and
coding data and developing theory
• Clarify how credibility is established in
qualitative data analysis
• Discuss the steps involved in writing a
qualitative research report

Nature of Qualitative Data Analysis
• Accuracy of qualitative analysis is based on
the rigor of the process followed while
collecting and analyzing data
• Qualitative research is useful in providing
knowledge for decision makers
– Benefits research that aims to understand
psychoanalytical or cultural phenomena

Qualitative Versus Quantitative
Analyses
Qualitative data
• Textual and visual
• Goal – Increase
understanding
• Ongoing and iterative
• Employs member checking
– Member checking: Asking key
informants to read a
researcher’s report to verify
that the analysis is accurate
• Inductive in nature
Quantitative data
• Numerical
• Goal – Quantify the
magnitude of variables and
relationships
• Guided entirely by
researchers
• Describes categories,
themes, and patterns prior
to data collection

Data Reduction
• Categorization and coding of data
– Part of the theory development process in
qualitative data analysis
• Consists of interrelated processes
– Categorization and coding
– Theory building
– Iteration and negative case analysis
Copyright © 2017 McGraw-Hill Education. All rights reserved. No reproduction or distribution without the prior written consent of McGraw-Hill Education.
Steps in Data Reduction
• Categorization: Placing portions of transcripts
into similar groups based on their content
– Categories may be coded
• Code sheet: Document containing the themes or
categories of a particular study
• Codes: Labels or numbers used to track categories in a
qualitative study
• Comparison: Developing and refining theory
and constructs by analyzing differences and
similarities in themes or types of participants
Copyright © 2017 McGraw-Hill Education. All rights reserved. No reproduction or distribution without the prior written consent of McGraw-Hill Education.
Steps in Data Reduction
(continued 1)
• Integration: Process of moving from the
identification of themes and categories to the
development of a theory
– Recursive: Relationship in which a variable can
both cause and be caused by the same variable
– Selective coding: Building a storyline around a
core category
• Other categories are related or subsumed
Copyright © 2017 McGraw-Hill Education. All rights reserved. No reproduction or distribution without the prior written consent of McGraw-Hill Education.
Steps in Data Reduction
(continued 2)
• Iteration: Working through the data several
times to modify early ideas
– Memoing: Writing down thoughts as soon as
possible after each interview, focus group, or site
visit
• Negative case analysis
– Deliberately looking for cases and instances that
contradict the ideas and theories that researchers
have been developing

Role of Tabulation
• Use in qualitative analyses is controversial
– Tabulation of data may mislead readers
• Helps quantify themes that occur repeatedly
• Promotes honest research
Copyright © 2017 McGraw-Hill Education. All rights reserved. No reproduction or distribution without the prior written consent of McGraw-Hill Education.
Data Display
• Common types
– Table that explains central themes in a study
– Diagram that suggests relationships between
variables
– Matrix that includes quotes for various themes
from representative informants

Drawing Conclusions and Verifying
Results
• Data analysis is considered credible when the
results are valid and reliable
– Emic validity: Affirms that key members within a
culture or subculture agree with the findings of a
research report
– Cross-researcher reliability: Degree of similarity in
the coding of the same data by different
researchers
Copyright © 2017 McGraw-Hill Education. All rights reserved. No reproduction or distribution without the prior written consent of McGraw-Hill Education.
Drawing Conclusions and Verifying
Results (continued 1)
• Credibility: Degree of rigor, believability, and
trustworthiness established by qualitative
research
– Triangulation: Addressing the analysis from
multiple perspectives
• Multiple data collection and analysis methods
• Multiple data sets, researchers, and time periods
• Different kinds of relevant research informants
Copyright © 2017 McGraw-Hill Education. All rights reserved. No reproduction or distribution without the prior written consent of McGraw-Hill Education.
Drawing Conclusions and Verifying
Results (continued 2)
• Peer review: External qualitative methodology
or topic area specialists are asked to review a
research analysis

Exhibit 9.9 – Threats to Drawing Credible
Conclusions in Qualitative Analysis
• Salience of first impressions or of observations of highly concrete or
dramatic incidents.
• Selectivity which leads to overconfidence in some data, especially
when trying to confirm a key finding.
• Co-occurrences taken as correlations or even as causal
relationships.
• Extrapolating the rate of instances in the population from those
observed.
• Not taking account of the fact that information from some sources
may be unreliable.

Exhibit 9.10 – Making Recommendations Based on
Qualitative Research When Magnitude Matters
• “The qualitative findings give reason for optimism about market
interest in the new product concept… We therefore recommend that
the concept be further developed and formal executions be tested.”
• “While actual market demand may not necessarily meet the test of
profitability, the data reported here suggest that there is widespread
interest in the new device.”
• “The results of this study suggest that ad version #3 is most
promising because it elicited more enthusiastic responses and
because it appears to describe situations under which consumers
actually expect to use the product.“
