“All progress is born of inquiry. Doubt is often better than overconfidence, for it leads to

inquiry, and inquiry leads to invention”

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

Page 10: Anna Bykova, researcher, PhD student Design_A... · Exploratory Research Design Descriptive and Diagnostic Research Design ... These studies require unbiased attitude of the Researcher

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

Page 12: Anna Bykova, researcher, PhD student Design_A... · Exploratory Research Design Descriptive and Diagnostic Research Design ... These studies require unbiased attitude of the Researcher

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

Page 13: Anna Bykova, researcher, PhD student Design_A... · Exploratory Research Design Descriptive and Diagnostic Research Design ... These studies require unbiased attitude of the Researcher

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

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

Page 21: Anna Bykova, researcher, PhD student Design_A... · Exploratory Research Design Descriptive and Diagnostic Research Design ... These studies require unbiased attitude of the Researcher

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.

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

Page 29: Anna Bykova, researcher, PhD student Design_A... · Exploratory Research Design Descriptive and Diagnostic Research Design ... These studies require unbiased attitude of the Researcher

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.

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
