Identifying a Suitable Research Problem
Address an important question
The answer should make a difference
Advance the frontiers of knowledge by
leading to new ways of thinking
suggesting possible applications
paving the way for further research in the field

When Considering A Research Problem
Select a research problem
for more than self-enlightenment
to do more than compare two sets of data
to contribute something new
to identify and interpret a relationship
that has more than a yes/no answer

Finding a Legitimate Research Problem
Look around you
Read the literature
Seek the advice of experts
Attend professional conferences
Choose a topic that intrigues and motivates you
Choose a topic that others will find interesting and worthy of attention
Be realistic

Stating the Research Problem
State the problem clearly and completely
Think through the feasibility of the project that the problem implies
Say precisely what you mean
Absolute honesty and integrity are the rule
Reflect an open mind about the solution
Edit your work

Dividing the Research Problem Into Subproblems
Most problems are too big to tackle
Identify subproblems
A small number of completely researchable units
Subproblems add up to the totality of the problem
Subproblems clearly tie to the interpretation of the data

Identifying Subproblems
Take a paper-and-pencil approach
Write down the problem
Highlight key words/ideas to explore
Reorganize the ideas to identify the overall research design
Use brainstorming/mind-mapping software
Construct graphic networks of interrelated concepts, terms, and principles

Resolving Pseudo-subproblems
Pseudo-subproblems are procedural issues
decisions must be made before resolving the research problem and its subproblems

Delineating the Problem
Every problem has a setting to establish
State a priori hypotheses
Identify specific variables
Define the terms
State the assumptions
Identify delimitations and limitations

Stating a priori hypotheses
Specify the research hypothesis
Educated guesses that researchers hope their data might support
Recognize the null hypothesis
“There will be no patterns in the data.”
Scientists support a research hypothesis by showing, statistically, that its opposite—the null hypothesis— is probably not true

Identifying Variables
Explicit identification of variables at the beginning of a study is most common in quantitative research, especially in experimental studies
Identification of variables helps the researcher choose
an appropriate research design
an appropriate statistical analysis

Identifying Variables
Variable: any quality or characteristic in a research investigation that has two or more possible values
Independent variable
researcher studies this variable as a possible cause of something else (may manipulate)
Dependent variable
potentially influenced by the independent variable, that is, may depend on the independent variable

Identifying Variables
Example:
The consistency of ice cream (dependent variable – DV) depends on the temperature at which it’s stored (independent variable – IV)
High temperatures cause ice cream to melt, whereas low temperatures cause ice cream to be solid

Mediating Variables
Mediating variables help explain why an independent variable has a particular effect on a dependent variable
Independent variable influences mediating variable, which in turn influences the dependent variable

Mediating Variables
For example
confidence level effort performance
confidence level (IV) influences effort (mediator)
effort (mediator) influences performance quality (DV)
high confidence more effort great performance
low confidence less effort okay performance

Moderating Variables
Moderating variables influence the nature & strength of relationship between IV and DV

Moderating Variables
For example:
family income during childhood problems later in life
low income + high maternal warmth fewer problems
low income + low maternal warmth more problems
high income + low maternal warmth more problems
income (IV) does NOT influence maternal warmth (moderator)

Defining Terms
Each term should be defined as it will be used by the particular researcher
Operational definition: the definition of a characteristic or variable in terms of how it will be measured in the research study

Leedy & Ormrod

Defining Terms
Examples
self-confidence = score on a self-report questionnaire that has items such as “I can usually achieve what I set out to do” and “I think of myself as a smart person”
popularity = number of peers who specifically identify an individual as being a desirable social partner

Stating assumptions
All assumptions that have a material bearing on the problem should be openly and unreservedly set forth
A statement of the assumptions is necessary for others to evaluate the conclusions of the study
A statement of the assumptions reveals what the researcher may be taking for granted with respect to the problem

Identifying delimitations
Delimitations are statements about what the researcher is not going to do.
The researcher must distinguish between what is and what is not relevant to the problem
For example, “I am interested in characteristics of X. I am not going to worry about influences on X.”
Practical Research: Planning and Design, 11/e
Leedy & Ormrod

Identifying limitations
The researcher must acknowledge weaknesses (limitations) that might cast doubt on results and conclusions
For example:
“My sample is small and possibly not representative”
“I have certain personal biases, such as X and Y, that may affect my observations and interpretation”

In the first section of a proposal, you should outline:
The problem and its setting
Subproblems
A priori hypotheses
Variables
Assumptions, delimitations, and limitations
The importance of the study

Evaluating Your Proposed Research Project
Have you conducted a thorough literature search to justify the time and effort expended on your research project?
Have you looked at your research problem from all angles to minimize unwanted surprises?
What research procedures will you follow?

Evaluating Your Proposed Research Project
What research tools are available for you to use?
Can others read and understand your proposal?

Fine-Tuning Your Research Problem
Conduct a thorough literature review
Try to see the problem from all sides
Think through the process
Discuss your research problem with others
Remember that your project will take time
Remember that the first draft of your proposal will almost certainly not be your last
