Introduction
• Models should be developed based on Logic,
•
•
•
Theory and prior Empirical Evidence (LTE)
Variables chosen for the model should be based
on LTE.
When choosing predictors for a model, variables
that should be included should be the same
ones chosen for a regression, such as
sociodemographics, clinical, and psychosocial
relevant variables.
One should also take into account adding all
appropriate confounders to the model.
Causation
“Principle by which cause and effect are
established between two variables. It requires
that there be a sufficient degree of association
(correlation) between the two variables, that
one variable occurs before the other, (that one
variable is clearly the outcome of the other), and
that there be no other reasonable causes for the
outcome. Although in its strictest terms
causation is rarely found, in practice strong
theoretical support can make empirical
estimation of causation possible.” (p. 579)

SETTING UP THE MODEL
• Models should be developed based on Logic,
Theory or prior Empirical evidence.
• Variables should be temporally ordered with the
most antecedent in time on the left hand side of
the model.
• Create hypotheses based on the bivariate
relationships of the variables in the model a
priori to any analyses.
• Run correlations on all variables. Draw in paths
of all significant relationships. This will be the
initial model.

Writing Research Purpose Statements,
Questions, and Hypotheses and
Planning your Analyses

WHAT are your research purpose
statements, questions, or hypotheses?
HOW will the variables be operationalized?
What is YOUR analysis plan?

WHAT are your research purpose
statements, questions, or hypotheses?
HOW will the variables be operationalized?
What is YOUR analysis plan?
Where to start? HERE!!!

What do I use a Hypotheses, a Research
Question, or Research Purpose
Statements?
 It really doesn’t matter. These are very
similar. However, there are subtle
differences. It is really the choice of the
investigator or your dissertation advisor.
Hypotheses
vs.
Research Questions and
Research Purpose Statements
What is a Hypothesis?



Remember back in grade school when
Sister Alberta Einstein told you it was an
“educated guess”. Well that is what it is
an “educated guess”.
It is created based on Logic, Theory, or
Prior Empirical Evidence (LTE).
It is more specific than Research
Questions or Research Purpose
Statements.
What are Hypotheses?


It is more specific than Research
Questions or Research Purpose
Statements.
It includes a direction. (Hey what do you
mean direction?)


To have a quantifying statement such as: “higher or
lower”, “more or less”, “larger or smaller”, “positive or
negative relationship”
This will also allow for a one-tailed statistical
significance test.
An Example of a Hypothesis?
It is hypothesized that in older hospital
patients, those with higher levels of
optimism will have lower levels of
depressive symptoms.
Another way to state this is:
 It is hypothesized that in older hospital
patients, optimism will be negatively
related to depressive symptoms.

Tips for Writing Hypotheses



If you have 2 variables state whether it is
a relationship, a comparison, or predictive
in nature.
State the Independent Predictor Variable
and Dependent Outcome Variable in that
order
State direction in describing variables (e.g.
“more” “less”)
Tips for Writing Hypotheses






Name Populations
Be Specific
Use plural forms to represent groups
Do not use two different terms to refer to the
same variable within a single hypothesis or
across several hypotheses.
Single sentence can have multiple hypotheses.
For multiple related hypotheses use a numbered
list (bullet points).
What are Research Questions
and Research Purpose
Statement?
Why are they lumped together?
 They are conceptually identical.
 They are just stated differently.
 They are more general in nature.

What are Research Questions
and Research Purpose
Statement?



Often used in exploratory, pilot studies
(“sailing unchartered waters”), when
trying to identify relationship or
comparisons.
They are non-directional. They do not
have quantifying statements.
Used for a two-tailed statistical
significance test.
Example of a Research
Questions and a Research
Purpose Statement?

Research Question:


In older hospital patients, how is their level of
optimism related to their level of depressive
symptoms?
Research Purpose statement:

The purpose of this research is to identify
how levels of optimism are related to levels of
depressive symptom in older hospital patients.
Tips for writing Research
Questions and Research
Purpose Statements?

Do not state a research questions that
have a “yes” or “no” answer


In older hospital patients, is their level of
optimism related to their level of depressive
symptoms?
If you have 2 variables state whether it is
a relationship, a comparison, or predictive
in nature.

Questions and Research
Purpose Statements?




State the Independent Predictor Variable
and Dependent Outcome Variable in that

Name Populations
Use plural forms to represent groups
Recommended for no relationships (e.g.,
for descriptives), qualitative, and new or
contradictory (to previous research) topic
Tips for writing Research
Questions and Research
Purpose Statements?




Use plural forms to represent groups
Do not use two different terms to refer to the
same variable within a single Research
Question/Purpose or across several Research
Question/Purposes.
Single sentence can have multiple hypotheses.
For multiple related Research Question/Purposes
use a numbered list (bullet points).
Where to start? HERE!!!

What QUESTIONS are you trying to answer?
 Are
you testing:
 Differences
between groups?
 Relationships between variables?

Now that you have your
research question, purpose
statement or hypotheses, you
have to decide on your research
design.
Are you looking for an experimental
or a non-experimental design?

Experimental – researchers give treatment
and observe changes in behaviors.

Could be with a control vs. treatment group
design
R O X O
R O
O

Could be just with a treatment group
O X O
Are you looking for an experimental
or a non-experimental design?

Non-Experimental – researchers do not
give treatments and describe subjects as
they naturally exist without experimental
treatments.


Causal Comparative Study – target group (
e.g., with an illness) vs. control group (e.g.,
absent of illness) and match by characteristics
Other examples: surveys, case studies,
longitudinal, correlational, qualitative, chart
reviews
Hey Chris,
Can you touch base on
Sampling
You Betcha, I Can
Types of Sampling


Simple random sampling – every member
of population has equal chance of being
included in sample.
Samples of convenience – Used with hard
to get samples, identifying support for
new theory. Often used for pilot work
Types of Sampling


Stratified random sampling – divide
sample into strata. Match % of sample
with % in population. Reduces sampling
bias
Cluster Sampling – Draws groups instead
of individuals (e.g., Churches, schools)
Types of Sampling


Purposive sampling – select from
individuals whom will be a good sources of
information (e.g., caregivers)
Snowball Sampling – locate participants
who are hard to find from other like
subjects.
