The document discusses the process of selecting, refining, and defining research problems. It begins by distinguishing between a research topic (a broad area of interest) and a research problem (a specific unsatisfactory situation that requires investigation). A good research problem identifies a knowledge gap within the research topic. The document provides examples of how to write a problem statement, research purpose statement, and research question. It also discusses developing a research hypothesis and the different types of hypotheses. The overall process involves narrowing a topic to a clearly defined research problem.

2. 2
Research Topic: The broad general area
expected to investigate. It is a broad idea or concept
from which many problems may be delineated.
Research Problem: A situation or circumstance
that requires a solution to be described, explained, or
predicted. It is an unsatisfactory situation that wants
you to confront.

3. 3
If there is a knowledge gap in an area
that need to be investigated, the research
problem identifies this gap. Where as the
research topic is simply a broad area of
interest, the research problem identifies
what is problematic about that topic.
Research Statement: A statement specifies
exactly what is being studied.

4. 4
The research statement should include six
elements:
Information about the research topic that provoked
the study
The scope of the problem (e.g.. how many people
are affected by it).
Why it is important to study the problem

5. 5
The research statement should include six
elements:
• How nursing science would be influenced by the
study
• General characteristics of the population of
interest
• The overall goal or aim of the study or the
question to be answered.

6. 6
Hazardous noise is an important occupational
health problem because it leads to hearing loss
and may lead to increased stress and other
deleterious physiological effects… More than 30
million workers are exposed to hazardous noise
on the job…Use of hearing protection devices,
specifically ear plugs is known to reduce noise
exposure and prevent noise – induced hearing
loss… there are, however, relatively few
investigators who have examined factors related
to the low use of hearing protection by workers.
Example of a problem statement

7. 7
It is the specific aim or goal hope to be
accomplished. It reflects “ why the
problem is being studied”
Example of a purpose statement:
The purpose of this study is to examine the
relationship between nurse’s job
satisfaction and tendency to leave.
Research Purpose

8. 8
It is a direct rewording of the statement of the
purpose phrased interrogatively rather than
declaratively
 Questions that are simple and direct invite an
answer and help to focus attention on the
kinds of data needed to provide that answer.
Research Question

9. 9
Example of a research question:
 What is the relationship between
the nurses’ job satisfaction and
their tendency to leave the work
setting?
Research Question

10. 10
Where do ideas for research
problems come from?
Social issues
Ideas from external sources
Research priorities
Clinical experience
Nursing literature
Sources of research problems

11. 11
Step 1: Selection of the research topic:
write down general areas of interest
At this stage, it doesn’t matter if the terms
used are broad or specific, abstract or
concrete., The important point is to put ideas
on papers.

12. 12
Step 1: Selection of the research topic:
Then a list of ideas can be classified into
Interesting topics.
Familiar topics.
Perplexing topics
Feasible/not feasible topics
And then, choose the most suitable one to
work in

13. 13
Step 2: Contemplating the ideas : then
explore the phenomena by examining the
following eight areas
1. The topic’s, situation’s problem’s precipitating
factors.
2. How it is exactly viewed or perceived by the
researcher.
3. What are the responses of others who are
involved in the situation?
4. The personal involvement in the situation.

14. 14
Step 2: Contemplating the ideas :
5. Emotions felt.
6. Values and biases inherent in or related to the
topic/situation.
7. Risk factors associated with searching this
topic/situation/problem.
8. What contribution the research would offer.

15. 15
Step 3: Narrowing the topic
 Once a research topic has been specified and
contemplate, the researcher must then narrow it
down in order to develop a research problem.
 This is done through generating questions from
the research topic.
 List of questions can be developed from the
research topic, and then investigated in relation
to its feasibility to research.

16. 16
 Reviewing the related literature at this stage
may throw light on:
Theoretical framework.
Methodology.
Data collection methods.
Data collection tools

17. 17
 Data collection techniques.
 Sampling method…etc.
Review of literature will also help to identify
what is known and what is not known about
the research problem. Therefore, the
research problem could be specified and
stated at this point.

18. 18
Step 5: Writing the statement of the
research problem :
 Expressed in a statement
 This statement serves as a guide to the
researcher in the course of designing the
study.

19. 19
 Step 5: Writing the statement :
The problem statement should have the
following characteristics:
 Identify the key variables in the study.
 Express a relationship between two or more
variables. (If not descriptive).
 Specify the study population.
 Imply the type of the research.
 Identify the study setting.

20. 20
 The problem statement could be done
in two forms:
 Declarative: “The relationship
between the nurses’ job satisfaction
and tendency to leave work”
 Interrogative: “ Is there a relationship
between the nurses’ job satisfaction
and tendency to leave work?”

21. 21
 Time: enough time will be available for the
various steps of the research.
 Timing :When the timing requirement of a
task do not match
 Money : the researcher should ask the
following questions:
 Will I have enough money to complete this
research?
 Will be any sources for funding the research?
 Does the anticipated cost outweigh the value of
the expected findings?
Evaluation of the research
problem

22. 22
 Availability of research participants:
 Ethical consideration
 Facilities and equipment
 Co operation of the others
 Researchability
 Qualifications and experience of the
researcher
 Significance of the problem

23. 23
 It is the research’s prediction of the
outcome of the research study. That
is the expected relationship
between the study variables.
 Thus, RESEARCH HYPOTHESIS
translates the research purpose into
a clear prediction of the expected
results or outcome of the study

24. 24
Importance of R.H.:
 It provides direction for the type of
research (i.e. design, sampling,
data collection .. etc.).
 Suggests the type of statistical
analysis to be used in the study.
 Identifies the variables to be
manipulated and/or measured

25. 25
How to state a R.H.:
 Research hypothesis should be stated
clearly, concisely, measurably, and in the
present tense.
 For a hypothesis to be stated clearly,
concisely, and measurably, three criteria
should be considered:

26. 26
Three criteria should be considered:
1. A relationship should be addressed in
each hypothesis.
2. The variable/condition/relationship must
be testable or measurable.
3. The aim of the research guides what is
included in the research hypothesis.

27. 27
When the research aim is to describe, the R.H. will
include the target population and study variables.
When the research aim is to explore, the R.H.
makes prediction about population and the
relationship among study variables.
When the research aim is to predict, the R.H.
concentrates on the population and independent
variables.

28. 28
Simple
 It predicts the relationship obetween one independent
variable and one dependent variable.
Example:
 Newborns of smoking mothers (I.V) have lower
birth weight (D.V.) than those of non-smoking
mothers.
 Lower levels of exercise postpartum (I.V) will be
associated with greater weight retention (D.V )
Types of hypothesis

29. 29
Complex
 It predicts the relationship between 2 or more I.V. and 2 or
more D.V.
Example:
 Structured preoperative support (IV).is more
effective in reducing surgical patient’s perception
of pain (D.V) and request of analgesics (D.V)
than structured post operative support (i.v.)
Types of hypothesis

30. 30
Associative
 It predicts an association between the I.V. and
the D.V. without specifying either a directional
or causal relation.
Example:
 Maternal age (I.V.) is associated with
pregnancy complications (D.V)

31. 31
Causal
 It predicts a cause-and effect relationship between the
I.V. and D.V.
Example:
 Older mothers (I.V.) give birth to newborns with
lover age (D.V.) than those of younger mother
(I.V)

32. 32
Null
 It predicts no relationship between I.V. and D.V.
 It is used when statistical testing procedures
are applied to the data.
Example:
 There is no relationship between maternal
smoking and newborn’s birth weight.

33. 33
Alternative
 It is the opposite of the null hypothesis. So, it predicts
a relationship between the I.V. and D.V.
Example:
 All the previous examples are alternative hypotheses.
