A - RESEARCH
STATEMENT
INTRODUCTION
 Fundamental first step in the research process.
 It is the most difficult and challenging phase in the
research project.
 It is the research scholar’s
IDENTIFICATION/RECOGNITION OR
PERCEPTION of a problem
RESEARCH PROBLEM
 It is a situation that needs solution.
 It is a gap in knowledge that needs to be filled
Example:
“Everybody wants to go to heaven but nobody
wants to die”
Dying looks like a problem that needs a solution yet
there is no
possible solution to it. People must die.
A research on people can live forever makes little
or no sense. So it is described as a incongruence
(Not being suitable)
Research problem
 Is used in research work as a claim that outlines
the problem addressed by a study.
 Should address an existing gap in knowledge in
the field and lead to further research.
 To write a persuasive problem statement, need
to describe : (a) the ideal, (b), the reality, and (c)
the consequences.
Problem Statement
Hernon and Schwartz (2007) defined in the following points:
a) Clarity and precision
b) Identification of what would be studied,
c) Identification of an overarching question and key factors or
variables;
d) Identification of key concepts and terms- articulation of the
boundaries or parameters; generalizability; conveyance of
the importance, benefits, and justification
e) No use of unnecessary jargon; and
f) Conveyance of more than the mere gathering of
descriptive data providing a snapshot.
PROBLEM STATEMENT
 It is the description of an issue currently existing
which needs to be addressed
 It provides the context for the research study and
generates the questions which the research aims
to answer
PURPOSES OF RESEARCH
STATEMENT

OBJECTIVES
RESEARCH OBJECTIVES
 Is a clear, concise, declarative statement.
 Provides direction to investigate the variables under
the study
 Focus on the ways to measure the variables.
 Summarize what is to be achieved.
IMPORTANCE OF OBJECTIVE
 Research: organized investigation of a problem;
investigator attempts to gain solution to a problem.
 A clearly defined objective
are very important to get the right solution
directs a researcher in the right direction.
are important feature of a good research study.
 Without a clear objective a researcher is aimless and
directionless in conducting the study.
 Without focused objectives, no replicable scientific
findings can be expected
CHARACTERISTICS OF
OBJECTIVES
SMART
 Specific: talk in a precise and clear way about what you
are going to do.
 Measurable: how will you know when you have achieved
your aim?
 Achievable: make sure that you aren’t overly ambitious.
 Realistic: recognize the time and resource constraints.
 Time constrained: determine when each objective needs
to be completed.
NEED FOR OBJECTIVES
FOCUS A clearly defined research objective will help
the researcher to focus on the study.
The formulation of research objectives helps
in narrowing down the study to its essentials.
It will avoid unnecessary findings, which
otherwise lead to wastage of resources
AVOID
UNECESSARY
DATA
Helps the researcher to avoid unnecessary
accumulation of data that is not needed for the
chosen problem.
ORGANIZATION The formulation of objectives organize
the study into a clearly defined parts
or phases.
The objectives help organize the study
results in to main parts as per the
preset objectives.
GIVES
DIRECTION
A well formulated objective will facilitate
the development of research
methodology.
It will help to orient the collection,
analysis, interpretation & utilization of
data.
when developing
research objectives
1. Be presented briefly and concisely
2. Be presented in logical sequence
3. Be realistic (achieved within the expected timeframe &
within the available resources)
4. Be phrased in operational terms
5. Use action verbs that are specific enough to be
evaluated or measured (assess, determine, compare,
verify, calculate, describe)
6. Static once the study work begins (objectives should
not be moving targets)
RELEVANT, FEASIBLE, LOGICAL,
OBSERVABLE, UNEQUIVOCAL &
MEASURABLE.
TYPES OF RESEARCH
OBJECTIVES
General
(Primary)
 Are broad goals to be achieved.
 Is the aim and overview of the study.
 Usually one general objective in each study.
 States what the researcher expects to achieve by the
study in general terms.
 Are met through meeting the specific objectives.
Specific
(Secondary)
 Are short term, narrow in focus & many in number..
 General objectives are broken into small logically
connected parts to form specific objectives
 Are clearly specify what the researcher will do in the
study, where and for what purpose the study is done.
C - RESEARCH
HYPOTHESIS
HYPOTHESIS
 Is a formal tentative statement of the expected relationship
between two or more variables under the study.
 Helps to translate the research problem and objectives into a
prediction of the expected results or outcomes.
 A clearly stated hypothesis includes
 the variables to be manipulated or measured
 identifies the population to be examined and
 indicates the proposed outcome for the study.
 Plays an important role in the theory building.
DEFINITION
 “Hypothesis is a tentative prediction or
explanation of the relationship between two
variables.”
 It implies that there is a systematic relationship
between an independent and dependent
variable”.
IMPORTANCE OF
HYPOTHESIS
 Enables to objectively investigate new areas of
discovery, helps in theory building.
 Provides objectivity, directions, clear and specific
goals.
 Helps selecting sample and research
procedures to meet the set goals.
 Provides a link between theories and actual
practical research.
 Serves as a bridge between theory and reality.
Cont - -
-
 Suggests the methodology to be chosen to
conduct the study.
 Is a tentative statement of the anticipated results,
give direction to proceed.
 Stimulates the thinking process.
 Provides directions about the methodology to be
chosen & techniques of data analysis;
understanding what to expect from the results.
 Serves as a framework for drawing conclusions.
 Without a hypothesis a research would be an
aimless wandering.
CHARACTERISTICS
 Must be written in declarative form using present tense.
 Must contain variables, population under study & be
relevant to research problem & objectives.

TYPES OF HYPOTHESIS
SIMPLE HYPOTHESIS COMPLEX HYPOTHESIS
Reflects the relationship
between two variables.
Reflects the relationship
between more than two
variables.
ASSOCIATIVE HYPOTHESIS CAUSAL HYPOTHESIS
Reflects a relationship
between variables that
occurs or exists in natural
settings without
manipulation.
(correlational research
studies).
Predicts the cause-and-effect
relationship between 2 or more
dependent and independent
variables in experimental or
interventional setting, where
independent variable is
manipulated by researcher to
examine the effect on dependent
variable
DIRECTIONAL HYPOTHESIS NON DIRECTIONAL HYPOTHESIS
Specifies not only the
existence, but also the
expected direction of the
relationship between
variables.
Reflects the relationship
between two or more variables.
Does not specify the
anticipated direction & nature
of relationship such as positive
or negative.
NULL HYPOTHESIS (Ho) RESEARCH HYPOTHESIS (H1)
Also known as STATITICAL
HYPOTHESIS.
Used for statistical testing
and interpretation of
statistical outcomes.
It states the existence of
relationship between two or
more variables.
H01: H1, H02: H2, H03: H3, H04: H4
CONCEPTUAL FRAMEWORK
 It illustrates what you expect to find through the
research.
 It defines the relevant variables for the study &
maps out how they might relate to each other.
 Construct a conceptual framework before
collecting data.
 Is often represented in a visual format.
STEP BY STEP GUIDE :
CONCEPTUAL FRAMEWORK
 Choose your topic: Decide (field of specialization).
 Do a literature review: Review relevant and updated
research from well-known scientific journals.
 Isolate the important variables. Identify the specific
variables described in the literature and figure out how
these are related. Check abstracts, salient findings and
research paper’s summary.
 Generate the conceptual framework. By using mix of
the variables from the scientific articles and problem
statement serves as a reference in constructing the
conceptual framework.
DESIGNING
CONCEPTUAL FRAMEWORK
 A conceptual framework can be designed in many
different ways.
 Depends on what kind of relationships you expect to
find.
 To visualize our expected cause-and-effect
relationship, use the basic design components of
boxes, arrows, and lines.
Component Meaning
Box Variable
Arrow Causal relationship
Line Correlation
 To indicate a causal relationship, each arrow should start from
the independent variable (the cause) and point to the
dependent variable (the effect).
 Use a line when you expect a correlation between two
variables, but no cause-and-effect relationship

ANALYSIS OF DATA
Steps of data analysis
1. Data presentation: compilation, editing, coding,
classification, tabulation
2. Describing the data: (descriptive statistics)
3. Drawing the inference of data: (inferential
statistics)
4. Interpretation of data
DESCRIPTIVE STATISTICS
 Measures to condense data: frequency and %
distribution through tabulation and graphic
presentation
 Measures of central tendency: Mean, median,
mode
 Measures of Dispersion: Mean, mean deviation,
standard deviation & quartile deviation
 Measures of Relationship: correlation coefficient
(Karl Pearson & Spearman’s Rank)
INFERENTIAL STATISTICS
Concepts related to Inferential statistics : Type
I and II errors, Level of significance,
Confidence level, Degree of freedom
Test of Significance:
Parametric tests: (t-test, Z-test & ANOVA)
Nonparametric tests: (chi-square test, median test,
McNemar test, Mann-Whitney test, Wilcoxon Test &
Fisher’s exact test).
