How are research questions answered?
Ex: A mixed method study investigating the relationship between cultural acuity
and practitioner effectiveness
Data Collection / Sampling / Setting/

Who did you study and how did you select them?

Ex: Population is all employees of Intel – sample is Finance
Department
Measurement

How are numbers assigned to concepts?

Ex: Quality of Work Life – measured by the QOL index
Data Analysis

How are data manipulated and interpreted?

Knowledge is subjective
It’s the product of the context
in which its constructed
(ex. Copernicus)
Scientific knowledge is not a
“direct representation of the
natural world”
It’s based on systems of
thought that are culturally
and historically bound
Positivism




All knowledge is derived from
experience whether of the
mind or of the senses.
Evidence by what we can see,
hear, touch, taste, or smell
Is the basis of “The Scientific
Method”
Emphasizes the importance of
testability, reliability, validity,
and repeatability
Asserts that the researcher is
“bias-free”
Claims “objectivity”
Your theoretical perspective leads to your research design
Qualitative vs Quantitative Design
Quantitative







Tests or verifies theories or
explanations
Identifies variables to
study
Relates variables
Observes and measures
information numerically
Uses unbiased approaches
Uses statistical procedures
Largely deductive
reasoning
Qualitative







Takes place in the natural
setting
Uses multiple methods
that are interactive and
humanistic
Is emergent
Fundamentally interpretive
Researcher views social
phenomena holistically
Researcher reflects on who
he or she is in the inquiry
and is sensitive to how
that shapes the study
Largely inductive
reasoning

Secondary data: data that has been collected for some other purpose
Sampling: who AND how many to ask when you
can’t study the entire population


You are conducting a study of professional success factors
among CC alumni who are external consultants. What is
your best approach?
Two key questions:


Sampling is often a major limitation


Is the sample biased? Is the size adequate?
Failure to identify the population, sample of convenience,
volunteerism,
Sample size – bigger is not always better – “it all
depends…”

Your goal is to produce valid and credible sample data and
statistics that match the precision needed for the study
Probabilistic Sampling





Simple Random: every member of the population has an
equal probability of being sampled (use random # tables)
Systematic Sampling: select at intervals (e.g,. Starting at
18, every 50th listing is selected)
Stratified Sampling: grouping the study population into
strata and selecting a random sample within each stratum
(e.g., dividing the population by education – less than high
school, high school, no college diploma, college diploma,
then selecting a random sample)
Cluster: random selection of groupings from which all
members are chosen for the sample (e.g., geographic
groupings, intact groups)
Multi-stage: select a cluster, then sampling members of
the selected clusters
Non-probability
Non-probabilisticSamples
Sampling





Quota: ensures that certain characteristics of a population
sample will be represented (e.g., need 20 small business
owners, 10 minority, etc.)
Purposive: (Judgment) experienced individual selects
sample based on judgment about particular characteristics
(e.g,. Political polls)
Snowball: initial respondents are asked who else would
be appropriate for the study
Self-Selection: participants self-select into the study
Convenience: selecting people (units) who are most
conveniently available (e.g., college professor using
students)
How many interviews, surveys?

It all depends

Research Question
Variance of the population
Minimum of 30 for most statistical tests
More is better – to a point!
Interviews

Ask until you start to get repetition
Remember – the intent in qualitative research is not to generalize,
but to elucidate the particular, the specific

communication
Faculty stays on topic, uses
appropriate examples, invites
and answers questions – what,
how, who, when and where

week period where sleep falls
below 5 hours a night
# of hours of sleep per

their project

Measuring Variables: Scale construction


Scale – any measuring instrument (questionnaire,
interview, test) composed of one or more items
(questions, observations, etc…) that have logical
relationships with one another.
Standardized measures – don’t reinvent the
wheel. Source for standardized measures –

Journal articles, books, other thesis or dissertation
projects
KISS
Measure twice and cut once… the value of beta
testing your approach
Scale Example: Job Characteristics Hackman
and Oldham, 1975

Measures the degree to which a job is designed to be
motivating (the motivating potential of a job)

Five dimensions: skill variety, task identity, task
significance, autonomy and feedback





My job requires me to use a variety of skills.
My job allows me to see the finished products of my work.
Doing my job well affects others in some important way.
My job is designed so that I know when I have performed well.
My job allows me freedom to work with minimum supervision.
Scale Examples

Participation/Involvement Scale





I feel free to suggest new and better ways of doing
things.
I am asked how we can improve the way my work
group operates.
Sufficient effort is made to get the opinions and ideas
of people in this work unit.
Suggestions made by unit personnel are implemented
in our daily work activities.
Satisfaction




In general, I am satisfied with my job.
I have a sense of personal fulfillment at the end of the
day.
I am a valued member of my unit.
I would recommend an assignment in my unit to a
friend.
Validity and Reliability

Validity – does it measure
what it is supposed to
measure?

Many types of validity that
you need to consider
Reliability – is it

Major Decisions in
Questionnaire Design





What should be asked?
How should each
question be phrased?
In what sequence
should the questions be
arranged?
What questionnaire
layout will best serve
the research objectives?
How should the
questionnaire be pretested?
A survey is only as good as the questions it asks
