4. Three types of research designs
Qualitative research – exploring and
understanding the meaning individuals or
groups ascribe to a social or human problem.
Quantitative research – testing objective
theories by examining the relationship among
variables.
Mixed methods research – an approach to
inquiry that combines or associates both
qualitative and quantitative forms.

5. Qualitative vs. quantitative research
Criteria Qualitative Research Quantitative Research
Purpose To understand & interpret
social interactions.
To test hypotheses, look at
cause & effect, & make
predictions.
Group Studied Smaller & not randomly
selected.
Larger & randomly selected.
Variables Study of the whole, not
variables.
Specific variables studied
Type of Data
Collected
Words, images, or objects. Numbers and statistics.
Form of Data
Collected
Qualitative data such as
open-ended responses,
interviews, participant
observations, field notes, &
reflections.
Quantitative data based on
precise measurements using
structured & validated data-
collection instruments.

6. 6
Criteria Qualitative Research Quantitative Research
Type of Data
Analysis
Identify patterns, features,
themes.
Identify statistical relationships.
Objectivity and
Subjectivity
Subjectivity is expected. Objectivity is critical.
Role of
Researcher
Researcher & their biases may be
known to participants in the study,
& participant characteristics may
be known to the researcher.
Researcher & their biases are not
known to participants in the study, &
participant characteristics are
deliberately hidden from the
researcher (double blind studies).
Results Particular or specialized findings
that is less generalizable.
Generalizable findings that can be
applied to other populations.
Scientific
Method
Exploratory or bottom–up: the
researcher generates a new
hypothesis and theory from the
data collected.
Confirmatory or top-down: the
researcher tests the hypothesis and
theory with the data.
Qualitative vs. quantitative research

Criteria Qualitative Research Quantitative Research
View of Human
Behavior
Dynamic, situational, social, &
personal.
Regular & predictable.
Most Common
Research
Objectives
Explore, discover, & construct. Describe, explain, & predict.
Focus Wide-angle lens; examines the
breadth & depth of phenomena.
Narrow-angle lens; tests a
specific hypotheses.
Nature of
Observation
Study behavior in a natural
environment.
Study behavior under controlled
conditions; isolate causal effects.
Nature of Reality Multiple realities; subjective. Single reality; objective.
Final Report Narrative report with contextual
description & direct quotations
from research participants.
Statistical report with
correlations, comparisons of
means, & statistical significance
of findings.
Qualitative vs. quantitative research
8. Pragmatism – Philosophy behind MMR
Arises out of actions, situations, and
consequences rather than antecedent
conditions.
There is a concern with applications—what
works—and solutions to problems.
Instead of focusing on methods, researchers
emphasize the research problem and use all
approaches available to understand the
problem.

9. Reasons for “mixing”
The insufficient argument – either quantitative or
qualitative may be insufficient by itself
Multiple angles argument – quantitative and qualitative
approaches provide different “pictures”
The more-evidence-the-better argument – combined
quantitative and qualitative provides more evidence
Community of practice argument – mixed methods may
be the preferred approach within a scholarly community
Eager-to-learn argument – it is the latest methodology
“Its intuitive” argument – it mirrors “real life”

10. How methods can be mixed
Types of mixing Comments
Two types of research question. One fitting a quantitative approach and
the other qualitative.
The manner in which the research
questions are developed.
Preplanned (quantitative) versus
participatory/emergent (qualitative).
Two types of sampling procedure. Probability versus purposive.
Two types of data collection
procedures.
Surveys (quantitative) versus focus
groups (qualitative).
Two types of data analysis. Numerical versus textual (or visual).
Two types of data analysis. Statistical versus thematic.
Two types of conclusions. Objective versus subjective
interpretations. 10

Sequential explanatory design:
Characteristics
Viewing the study as a two-phase project
Collecting quantitative data first followed by
collecting qualitative data second
Typically, a greater emphasis is placed on the
quantitative data in the study
Example: You first conduct a survey and then
follow up with a few individuals who answered
positively to the questions through interviews
16. 16
Sequential explanatory design:
When do you use it?
When you want to explain the quantitative
results in more depth with qualitative data
(e.g., statistical differences among groups,
individuals who scored at extreme levels)
When you want to identify appropriate
participants to study in more depth
qualitatively
17. 17
The purpose of this two-phase, explanatory mixed methods
study will be to obtain statistical, quantitative results from a
sample and then follow-up with a few individuals to probe or
explore those results in more depth. In the first phase,
quantitative research questions or hypotheses will address the
relationship or comparison of __________ (independent) and
________ (dependent) variables with ___________
(participants) at ___________(the research site). In the
second phase, qualitative interviews or observations will be
used to problem significant _______(quantitative results) by
exploring aspects of the ________ (central phenomenon) with
_______ (a few participants) at ____________ (research
site).

Sequential exploratory design:
Characteristics
Viewing the study as a two-phase project
Qualitative data collection precedes quantitative
data collection
Typically, greater emphasis is placed on the
qualitative data in the study
Example: You collect qualitative diary entries,
analyze the data for themes, and then develop
an instrument based on the themes to measure
attitudes on a quantitative survey administered
to a large sample.
20. 20
Sequential exploratory design:
When do you use it?
To develop an instrument when one is not
available (first explore, then develop
instrument)
To develop a classification or typology for
testing
To identify the most important variables to
study quantitatively when these variable are
not known
21. 21
The purpose of this two-phase, exploratory mixed methods
study will be to explore participant views with the intent of
using this information to develop and test an instrument with
a sample from a population. The first phase will be a
qualitative exploration of a _______(central phenomenon) by
collecting ___________(data) from ____________
(participants) at _______ (research site). Themes from this
qualitative data will then be developed into an instrument (or
survey) so that the __________ (theory and research
questions/hypotheses) can be tested that ________ (relate,
compare) ____________ (independent variable) with
__________ (dependent variable) for _________(sample of a
population) at _________ (research site).

23. Sequential transformative design:
Characteristics
23
Has two distinct data collection phases
A theoretical perspective is used to guide the
study
Purpose is to use methods that will best
serve the theoretical perspective of the
researcher
25. 25
Concurrent triangulation design:
Characteristics
Collecting both quantitative and qualitative data
Collecting these data at the same time in the
research procedure
Analyzing the quantitative and qualitative data
separately
Comparing or combining the results of the
quantitative and qualitative analysis
Example: collect survey data (quantitative) and
collect individual interviews (qualitative) and then
compare the results
26. 26
Concurrent triangulation design:
When is it used?
When you want to combine the advantages of
quantitative (trends, large numbers,
generalization) with qualitative (detail, small
numbers, in-depth)
When you want to validate your quantitative
findings with qualitative data
When you want to expand your quantitative
findings with some open-ended qualitative data
(e.g., survey with closed- and open-ended data)
28. Concurrent embedded design:
Characteristics
One data collection phase during which both
quantitative and qualitative data are collected
(one is determined to be the primary method).
The primary method guides the project and the
secondary provides a supporting role in the
procedures.
The secondary method is “embedded” or
“nested” within the predominant method and
addresses a different question.

29. 29
The purpose of this concurrent mixed methods study
is to better understand a research problem by
converging both quantitative (numeric) and qualitative
(text or image) data. In this approach, ___________
(quantitative instruments) will be used to measure the
relationship between the ________ (independent
variables) and __________ (dependent variables). At
the same time in the study, the __________ (central
phenomenon) will be explored using _____________
(qualitative interviews, documents, observations,
visual materials) with _________ (participants) at
____________ (the research site).

31. Concurrent transformative design:
Characteristics
Guided by a theoretical perspective.
Concurrent collection of both quantitative and
qualitative data.
The design may have one method embedded in
the other so that diverse participants are given a
choice in the change process of an organization.
