“All progress is born of inquiry. Doubt is often better than overconfidence, for it leads to
inquiry, and inquiry leads to invention”
Hudson MaximU.S. inventor and chemist who invented a
variety of explosivesDefenseless America, 1916
Research is Search for Knowledge It is an Art of Scientific Investigation Systematized effort to gain new knowledge Research is an original addition to the
available knowledge, which contributes to it’sfurther advancement
Research is the search for knowledge, usingobjective and systematic methods to findsolution to a problem
To gain familiarity with new insights into a phenomenon
To accurately portray the characteristics of a particular individual, group, or a situation
To analyze the frequency with which something occurs
To examine the Hypothesis of a casual relationship between two variables

An attempt to find solution to an immediate problem encountered by a firm, an Industry, a business organization, or the Society is known as Applied Research
Gathering knowledge for knowledge’s sake is ‘Pure’ or ‘Basic’ or ‘Fundamental’ Research
The Research related to some abstract idea or theory is known as Conceptual Research. (Ex: Philosophers and Thinkers using this to developing new concepts)
Empirical Research relies on the observation or experience with hardly any regard for theory and system.
Research Problem is an unansweredquestion that a researcher might encounter inthe context of either a theoretical or practicalsituation
There should be an individual or a group whohave some difficulty or problem
There should be some objective to bepursued (A person or an organization whowants nothing cannot have a problem)
There should be more than one alternativemeans available to the Researcher.
There should be some doubt in the mind ofthe Researcher about the choice ofalternative means
what the researcher expects to achieve; solution to the research problem
B. Importance of Setting Objectives: give an indication of the variables to be studied guide in choice of research design indicate the data to be collected aid in planning analysis of results bases for interpretation of results
Researchability
Can be resolved through research
Does not require value judgment
Significance
Problem: affects a large population, has serious
morbidity consequences, is related to on-going projects
Answer: fills a gap in knowledge, has practical
application
Feasibility
Adequate number of subjects can be gathered
Procedures are technically possible
Information needed can be collected
Resources are available
Study can be completed within a reasonable
period
1. The Name of the Study2. The Purpose of the Study3. The Location where the study would
be conducted4. The Nature of Data Required5. From where the required Data can be
collected6. What time period the study would
cover7. The Type of Sample Design8. The Techniques of Data Collection9. The Methods of Data Analysis
It facilitates smooth conduct of the various stages of Research.
Makes Research Efficient to yield maximum information with minimum effort, time, expenditure
Plays a crucial role in attaining the reliability of the results obtained.
Exploratory Research Design Descriptive and Diagnostic Research Design Hypothesis-testing Research Design
The Researcher tests the Hypothesis of casual relationship between two or more variables
These studies require unbiased attitude of the Researcher
Flexible, Suitable, Efficient and Economical
Minimizes bias and Maximizes Reliability
No Experimental Error
Yields Maximum Information
It is a Predictive statement Must be tested by scientific
methods A hypothesis is a proposed
explanation for an observable phenomenon
Tentative answer to the research problem
Provides basis for testing statistical significance of findings
Precise and clear Capable of being put to test Must be stated in simple language Researcher must be able to test it within a
stipulated period A Hypothesis should explain what it actually
wants to explain. A Hypothesis must be derived from known
facts
Null Hypothesis (H0): The statistical hypothesis that states that there are no differences between observed and expected data.
to test safety of drugs and other interventions
for “proving” that a health belief is a myth or is erroneous
Alternative Hypothesis (H1):The alternative hypothesis is the hypothesis used in hypothesis testing that is contrary to the null hypothesis. It is usually taken to be that the observations are the result of a real effect (with some amount of chance variation superposed).
for testing risk and prognostic factors
for testing intervention
State H0 as Well as Ha
Specify the Level of Significance
Decide the Correct Sampling Distribution
Sample a random Sample and workout an appropriate Value
Calculate the Probability that Sample Result would diverge as widely as it has from expectations, if H0
were true
Sample is a certain portion of the population A Researcher adopts a Technique to select
the items of the Sample from the Population and that is called as Sampling Design.
Sample design must be done before Data Collection.
Type of Interview Sampling Unit Source List Size of Sample Parameters of Interest Budgetary Constraint Sampling Procedure
Define the Universe to be studied:
Finite or Infinite
Define Sampling Unit: Geographical or Social Area
Small Sampling Error Sample Design must fit into the Budget Controllable Bias Results of the Sample Study must be
applicable to the Universe, with confidence
Primary Data is a term for data collected on source which has not been subjected to processing or any other manipulation.
When Primary Data is Processed it becomes Information, the data collected for the first time
Secondary Data is the Data that has already been collected and used earlier by somebody or some agency
Primary Data is more accurate and authentic. Time, Money and labour is more involved in
Primary data Collection But in Statistical enquiries secondary data is
used. Primary Data is are collected only if there
exists no secondary data.
Direct Personal Interview Indirect oral interviews Information from correspondents Mailed Questionnaire methods Schedule sent through interviewers
It is accurate watchingand noting of phenomenaas they occur with regardto the cause and effect ormutual relations.
Quantitative Approach(Uses experimental, inferential and simulation
approaches to research) Qualitative Approach(Uses techniques like in-depth interview, focus
group interviews)
Editing – checking for completeness, consistency and accuracy of data
Coding - conversion of data into numbers or symbols which can be more easily tabulated and counted
Creation of data file - storing data for future processing
Summarization – creation of master tables, frequency tables, etc.
independent variable – variable which is assumed to be the factor or the cause
dependent variable – variable that is assumed to be the effect or outcome
confounding variable – variable other than the exposure variable under investigation that is a risk factor of the disease and is associated with but not a consequence of the exposure and is likewise associated with the dependent variable
Written plan of the research process
Guides investigator in executing project
Basis for evaluation of merit and feasibility of the project
