What is a simple definition of theory?
A theory is a carefully thought-out explanation for
observations of the natural world that has been
constructed using the scientific method, and which
brings together many facts and hypotheses.

What is the difference between Theory and
Practical?
• Theoretical learning is what the knowledge is about and the
practical application is how the knowledge learnt needs to be
implemented in certain real life situations. The mode of practical
application along with theory gives everyone a clear explanation
about the facts.

empiricism : Meaning
Dictionary Meaning of empiricism
• the theory that all knowledge is based on experience derived from
the senses.
Stimulated by the rise of experimental science, it developed in the
17th and 18th centuries, expounded in particular by John Locke,
George Berkeley, and David Hume.

What is empiricism?
Empiricism is a philosophical theory applicable in many disciplines,
including science and software development, that
human knowledge comes predominantly from experiences gathered
through the five senses.
In empiricism, knowledge is spoken of as a posteriori, or "from the
latter," meaning gained from experience. Simply put, empiricism is
the idea that all learning comes from only experience and
observations.

What is empirical theory in research?
Empirical research is research that is based on observation and
measurement of phenomena, as directly experienced by the
researcher. The data thus gathered may be compared against a
theory or hypothesis, but the results are still based on real life
experience.

What is an example of empirical?
It involves the use of observation to gather empirical data.
For example: 1.Consumers tend to consult first their
smartphones before buying something in-store.
Inductive reasoning is then conducted to frame a general
conclusion from the data gathered through observation.
2. Pharmaceutical companies use empirical research to try
out a specific drug on controlled groups or random groups
to study the effect and cause. This way they prove certain
theories they had proposed for the specific drug.

Deductive and Inductive theory
The main difference between inductive and deductive
reasoning is that inductive reasoning aims at developing a
theory while deductive reasoning aims at testing an
existing theory.
In other words, Inductive reasoning moves from specific
observations to broad generalizations.
Deductive reasoning works the other way around.
Both approaches are used in various types of research,
and it’s not uncommon to combine them in your work.

Inductive research approach
When there is little to no existing literature on a topic, it is common
to perform inductive research, because there is no theory to test.
The inductive approach consists of three stages:
Observation
A low-cost airline flight is delayed
Dogs A and B have fleas
Elephants depend on water to exist
Seeking patterns
Another 20 flights from low-cost airlines are delayed
All observed dogs have fleas
All observed animals depend on water to exist

17.
SHARDA SCHOOL OF DESIGN, ARCHITECTURE & PLANNING

Prof. (Ar.) Pramod Kumar Jain Course Title: Research Methodology
Developing a theory or general (preliminary) conclusion
Low cost airlines always have delays
All dogs have fleas
All biological life depends on water to exist
Limitations of an inductive approach
A conclusion drawn on the basis of an inductive method can
never be fully proven. However, it can be invalidated.
Example You observe 1000 flights from low-cost airlines. All of
them experience a delay, which is in line with your theory.
However, you can never prove that flight 1001 will also be
delayed. Still, the larger your dataset, the more reliable your
conclusions.

18.
Deductive research approach
When conducting deductive research, you always start with a theory. This is usually
the result of inductive research. Reasoning deductively means testing these theories.
Remember that if there is no theory yet, you cannot conduct deductive research.
The deductive research approach consists of four stages:
Start with an existing theory and create a problem statement
Low cost airlines always have delays
All dogs have fleas
All biological life depends on water to exist
Formulate a falsifiable hypothesis, based on existing theory
If passengers fly with a low cost airline, then they will always experience delays
All pet dogs in my apartment building have fleas
All land mammals depend on water to exist

Collect data to test the hypothesis
Collect flight data of low-cost airlines
Test all dogs in the building for fleas
Study all land mammal species to see if they depend on water
Analyze and test the data
5 out of 100 flights of low-cost airlines are not delayed
10 out of 20 dogs didn’t have fleas
All land mammal species depend on water
Decide whether you can reject the null hypothesis
5 out of 100 flights of low-cost airlines are not delayed = reject
hypothesis
10 out of 20 dogs didn’t have fleas = reject hypothesis
All land mammal species depend on water = support
hypothesis

20.
Limitations of a deductive approach
The conclusions of deductive reasoning can only be true if all
the premises set in the inductive study are true and the terms
are clear.
Example
All dogs have fleas (premise)
Benno is a dog (premise)
Benno has fleas (conclusion)
Based on the premises we have, the conclusion must be true.
However, if the first premise turns out to be false, the conclusion
that Benno has fleas cannot be relied upon.

Combining inductive and deductive research
Many scientists conducting a larger research project begin with
an inductive study. This helps them develop a relevant research
topic and construct a strong working theory. The inductive study
is followed up with deductive research to confirm or invalidate
the conclusion. This can help you formulate a more structured
project, and better mitigate the risk of research bias creeping
into your work.
Remember that both inductive and deductive approaches are at
risk for research biases, particularly confirmation
bias and cognitive bias, so it’s important to be aware while you
conduct your research.
