Research is the systematic process of collecting and analysing information (data) in order to increase our understanding of the phenomenon with which we are concerned or interested.
D e fi n i t i o n o f R e s e a r c h
• As a graduate student... To be able to read and
understand the empirical literature in your field; to become a critical consumer of information.
• As a graduate student preparing for a thesis or dissertation…
To be able to both design and implement your thesis or dissertation as well as future studies that interest you.
W h y D o I N e e d t o K n o w A b o u t R e s e a r c h ?
• As a future practitioner… To be able to intelligently participate in
research projects, evaluations, and studies undertaken by your institution.
• As an educated citizen ...To understand the difference between
scientifically acquired knowledge and other kinds of information.
W h y D o I N e e d t o K n o w A b o u t R e s e a r c h ?
Research is all about addressing an issue or asking and answering a question or solving a problem, so…Identify an issue, question, or problem. Talk with people who want or need your study.Find out what's already known about it. Talk with experts and/or read their reviews and the original research on the topic.
W h a t i s R e s e a r c h ?
Plan, cost, and do your study accordingly.Write it up and submit it for assessment. Better still, do a good job on it and submit it for publication Undergrad projects are sometimes good enough to publish. Your work will benefit more people if you publish it.

Re s e a r c h P r o c e d u r e
The problem is the Y of any research project. Without a focused problem, there is no research.
In order to be able to identify a research problem, a researcher needs to know what are the available sources.
A research problem is usually posed as a question, preferably a direct and simple one.
D e fi n i n g t h e R e s e a r c h P r o b l e m
►State your research problem.►Are there any sub-problems?►What is the background
(literature review) on this problem?
►What is good about tackling this problem? Why should we be interested in answering the research question?
D e fi n i n g t h e R e s e a r c h P r o b l e m
►Discuss your problem with peers and experts.
►Have you looked at this problem from all sides to minimize unwanted surprises?
►Think through the process. Are you capable of addressing the issue? Can you foresee any pitfalls in data collection and analysis? What tools are available for you to use?
►What research procedure will you follow?
Types of Research Problems:
1.Descriptive research – asks “what is” and suggests a survey research design;
2.Relationship research – asks what is the relationship between two or more variables and implies a correlational design.
3. Difference research – asks what is the difference between two or more groups/ approaches;
There are generally two ways of stating a research problem:
1.Declarative or descriptive – usually used in stating the main problem/ general objective
2. In question form – usually used in stating the sub-problems/specific objectives
In any study, you need to define the key terms or concepts in the statement of the problem to avoid confusion or ambiguity.
Two types of definitions:
1. Conceptual definition – definition of a term as given by authoritative sources (e.g. Webster’s dictionary; a well-known research study; textbook, etc..)
2. Operational definition – researcher’s own definition, based on how it will be used in the study
SEARCHING RESEARCH LITERATURE
►Hard Copies and Soft Copies►Online and Offline - Internet►Research Databases - Websites►Search Engines►Institutional Repositories►University and Institutional Libraries►Research Scholars and University/College
Teachers►Blogs - Groups and Networks
FORMATION OF HYPOTHESES►Hypotheses basically state the
assumption on the basis of which analysis is undertaken.
►There are two types of hypotheses►Research Hypotheses and Working
Hypotheses►The Research hypotheses relate to the
theoretical assumptions of the analysis While ►The working hypotheses are the statistical
hypotheses for statistical analysis of data.
To ensure the objectivity in the study of an identified problem, the researcher has to be clear as to what variables are to be examined or investigated.
• A variable is a property or characteristic that takes on different values.
• It is a symbol to which numbers or values can be attached or assigned.
Types of variables:
1. Independent variables – the cause supposed to be responsible for the bringing about change in a phenomenon or situation.
2. Dependent variables – the outcome of change brought about by change in the independent variable
3. Intervening variable – a variable whose existence is inferred but cannot be manipulated or controlled
4. Moderator variable – a variable that may or may not be controlled but has an effect on the research situation/phenomenon.
1.Independent variable: Education.
2.Dependent variables: Behavior, knowledge of colour
3.Intervening variable: Policies
4.Moderator variables: civil status, age, years of work experience
One way of making a study on a problem more focused is by delimiting it.
Delimiting research is giving full disclosure of what the researcher intends to do or does not intend to do.
When a researcher is able to set the scope and delimitation of his study, he can make his research manageable. At the same time, this can direct him to the choice of research method to employ.
Points for delimiting study:
1.Purpose of study
2.Time coverage of investigation
3.Geographical coverage of inquiry
4.Variables to be studied
5.Specific indicators of variables
6.Types and size of respondents if the study
7.Data collection tools

Designing the Research
After stating your researchproblem, you need to think About what approach you will use to the problem. Will it be quantitative or
qualitative?
Types of methodologies►QuaLitative Measures
●Descriptive●Numbers not the primary focus●Interpretive, ethnographic,
naturalistic
►QuaNtitative Measures●N for numbers●Statistical●Quantifiable
QuaNtitative measures
►CompareThings►Count Things►Survey People About Things
p < .05
QuaNtitative measures►Comparison studies
●Experimental and control groups●Instructional methodologies (Colaric;
Cudiner & Harmon)●Program assessment using before/after
analysis of research papers(Emmons & Martin)
