Research Design
 Research design is a framework or
blueprint for conducting a research project.
 It is a plan to be followed to answer
research objectives, research hypotheses,
and/or research questions.

Determine and Evaluate Research Design
Exploratory
Research
•Gathers preliminary information
that will help further define the
problem and suggest hypotheses.
Descriptive
Research
•Describes things as market
potential for a product or the
demographics and consumers’
attitudes.
Causal
Research
•Test hypotheses about causeand-effect relationships.

skills
Scientific, statistical
procedure and
translation skills
Very limited, only
preliminary insights and
understanding

What is Qualitative Research?
… is an effort to understand situations in their
uniqueness as part of a particular context and the
interactions there. This understanding is an end in
itself, so that it is not attempting to predict what
may happen in the future necessarily, but to
understand the nature of the setting –
what it means for participants to be in that setting,
what their lives are like, what’s going on for them,
what their meanings are, what the world looks like
in that particular setting – and in the analysis to be
able to communicate that faithfully to others who
are interested in that setting … the analysis strives
for depth of understanding
Patton (1985)

Qualitative Study – Exploratory
Design
 Objective is to explore or search through a
problem or situation to provide insights and
understanding.
 Purposes:
– Formulate a problem or define a problem more
–
–
–
–
precisely
Identify alternative courses of action
Develop hypotheses
Isolate key variables and relationships
Establish priorities for research
7
Common Qualitative
Methodologies
 Ethnography -the researcher (anthropologists)
looks at the entire group – more specifically a
group that shares a common culture – in depth
 Phenomenological Study - Attempts to
understand people’s perceptions, perspectives
and understandings of a particular situation
 Grounded Theory - To begin with the data and
use them to develop a theory – normally
substantive theory
 Case Study
 Content Analysis
 Basic or Generic Qualitative Study
8
Quantitative ResearchDescriptive Design
 Objective is to describe or establish a
relationship of something
– Purpose:
•
•
•
•
To describe characteristics
To estimate percentage
To determine perceptions
To determine the degree to which variables are
associated.
• To make specific predictions
9
Quantitative Research – Causal Design
– Objective is to obtain evidence of cause-andeffect relationships by means of
experimentation
– Purposes:
• Identify variables that are deemed the cause
and variables that constitute the effect of a
phenomenon.
• Predict the nature of the relationship
between causal variables and the effect to
be predicted.
10
So which methods to choose…..
 Depends on the purpose of the study
 Depends on the information sought
 Depends on resources available
 Depends on the time available to conduct
the study

IF YOU ARE GOOD WITH
NUMBERS AND YOU LIKE
TO SEE EVENTS AND
THINGS IN TERMS OF
NUMBERS
CONSIDER DOING QUANTITATIVE RESEARCH THAT
USES FANTASTIC STATISTICAL ANALYSES

 Probability Sampling
– When elements in the population have a
known chance of being chosen as subjects in
the sample have a known chance of being
chosen as subjects in the sample
– The sample can be confidently generalised to
the population
 Non-Probability Sampling
– When time or factors rather generalisability
become critical
– The sample cannot be confidently generalised
to the population
17
 Simple Random Sampling
– Every element in the population has a known and
equal chance of being selected as a subject
 Systematic Sampling
– Involves drawing every nth element in the population
starting with a randomly chosen element between 1
and n
 Stratified Random Sampling
– Population is first divided into meaningful segments;
thereafter subjects are drawn
 Cluster Sampling
– Groups that have heterogeneous members are first
identified; then some are chosen at random
18
Factors to consider when selecting sample size
 The variability in the population.
– This refers to the proportionate distribution of the characteristics
that are being studied.
 The required level of confidence.
– If a higher level of confidence is required in the result of the
research, then the larger the sample size is necessary.
 The required limits of accuracy.
– Generally, the larger the sample size, the more accurate the
results are likely to be as a predictor of population values.
 Allowance for non-response
– It is to be expected that non-response will occur in any the
survey. Therefore, it is best to make allowance for the nonresponse by increasing the sample size by the estimated amount
of non-response.
 Practical factors
– It is important for a researcher to consider the resource constraints. Time
and money are important factors to consider when selecting the
appropriate sample size.

In-Depth Interviewing
 Types of Interview questions?
Highly
Structured
Semistructured
 Wording of
 Mix of morequestions
and lesspredetermined
structured
 Order of
questions
question
predetermined
 Oral form of a
survey
Unstructured
 Open-ended
questions
 Flexible,
exploratory
 More like a
conversation
26
Example: studying the role of mentoring in
the career development of a lecturer
Highly
Structured
Semistructured
Unstructured
Begin by giving
each respondent
a definition of
mentoring
Ask the person
to identify
someone who is a
mentor
Ask each
lecturer to
describe his or
her understanding
of mentoring
Ask each
lecturer to think of
someone who is a
mentor
Ask the
respondent to
share how he or
she got to be a
mentor
Ask question
about the
influences or
factors that have
helped to shape
the respondent’s
career
27
Types of Questions
Example: Directors Training Program
Type of Question
Example
 Hypothetical Question: asks what the
respondent might do or what it might be like
in a particular question: usually begins with
“what if” or “suppose”
 Devil’s Advocate Question: challenges the
respondent to consider an opposing view
“Suppose it is your first day in
this directors’ training
program. What would it be
like?”
“Some people would say that
training program doesn’t
do any good to the
directors, especially those
who have been on the
board for a long time.
What would you say to
that?”
“What do you think the ideal
training program would be
like”
“Would you say that attending
directors’ training
programs would enhance
your role and
responsibilities as
28
director?
 Ideal Position Question: asks the
respondent to describe an ideal situation
 Interpretive Question: advances tentative
interpretation of what the respondent has
been saying and asks for a reaction
Questions to Avoid
Type of Question
Multiple Questions
Example
How do you feel about the
instructors and the
classes?
Leading Questions
What emotional problems
have you had since
losing your job?
Yes-or-No Question
Do you like the program?
Has returning to school
been difficult?
