IDENTIFIYING AND STARTING A RESEARCH PROBLEM
FORMULATING AND STATING
A HYPOTHESIS
A hypothesis is a researcher’s prediction of the research findings.
Researchers don't set out to prove a hypothesis but rather collect data that either support or do not support it.
Definition and Purpose of hypotheses in
Quantitative studies
. A good hypothesis states clearly and concisely the expected relations or differences between variables
A well-stated and well-defined hypothesis
must be testable.
Types of hypotheses
An inductive hypothesis is a generalization made from a number of observations.A deductive hypothesis is derived from theory
Stating the hypothesis
A general model for stating hypotheses is P who get X do better on Y than P who do not get X
Testing the hypothesis
The researcher selects the sample, measuring instruments, design, and procedures
Definition and Purpose of hypotheses in
Qualitative studies
Qualitative researchers do not state formal hypotheses prior to the study. but develop guiding hypotheses
Researcher may operationalize
the hypothesis through the development of
IDENTIFYING A RESEARCH PROBLEM
Identify in your area of expertise
particular interest to you.
Sources of research Problems
Main sources of research problems are:
Theories
Personal experiences
Previous studies
Electronic mailing lists
Library searches
Narrowing the Problem
Needs to be narrowed and focused into a manageable problem
Quantitative problems
Are usually narrowed quickly at the start of study
Qualitatives problems
Are usually narrowed until the searcher has more information
Stating the research Problem
The problem statement is the first item in
the introduction to a research plan and the introduction to the final research report.
A well-written problem statement for a
quantitative study generally indicates
the variables of interest
the specific relations
among those variables
the characteristics of the participants.
Qualitative research problems are usually stated
Characteristics of good Problems
Basic characteristics
The problem is of interest to the researcher
It's researchable using the collection and analysis of data
Problem has theoretical or practical
significance
Is ethical and doesn't harm participants in any way
Must be
a problem that can be adequately investigated
Developing research Questions
Breathes life into the research problem statements
Provides to the researcher with
an action plan for the development and
identification of research instruments.
