This PPT will give a brief idea about Definition, characteristics and types of Research. This is also discussed process of research and various sampling methods like probability Vs Non-probability sampling.

2. Research
Research is a
scientific and
systematic search
for pertinent
information on a
specific topic.

3. As per the dictionary definition it is a careful
investigation or enquiry especially through search
for new facts in any branch of knowledge
Characteristics of Research:
It is always Search for Knowledge
Its moves from Known to known
Systematic and careful inquiry
It has the Logic reason and evidence
It should fallow the scientific methods (Inductive &
Deductive)
It will formulate the generalisations & theories

4. Types of Research
Descriptive vs Analytical:
Descriptive research (Ex post facto research)
includes surveys and fact-finding enquiries of
different kinds. The main characteristic of this
method is that the researcher has no control
over the variables; he can only report what has
happened or what is happening.
Analytical research in this the researcher has to
use facts or information already available, and
analyze these to make a critical evaluation of
the material

5. Applied vs Fundamental:
Applied research aims at finding a solution for an
immediate problems facing by a society or an
organization.
Fundamental research is mainly concerned with
generalizations and with the formulation of
theory. (gathering knowledge for knowledge’s
sake)

6. Quantitative vs Qualitative:
Quantitative research is based on the
quantitative measurements of some
characteristics. It is applicable to phenomena
that can be expressed in terms of quantities.
Qualitative research is concerned with
qualitative phenomenon, it is a method of
inquiry that develops understanding on human
and social sciences, to find the way people
think and feel.

7. Conceptual vs Empirical:
Conceptual research is that related to some
abstract ideas or theory. It is generally used by
philosophers and thinkers to develop new
concepts or to reinterpret existing ones.
Empirical research (Experimental) relies on
experience or observation alone, often
without due regard for system and theory. It is
data based research, coming up with
conclusions which are capable of being verified
by observation or experiment.

8. Other Types of Research:
 One-time research
 Longitudinal research
 Field setting research / Laboratory research
 Clinical or diagnostic research
 Historical research

9. Research Methods vs Methodology:
Research methods may be understood as all
those methods/techniques that are used for
conduction of research. Research methods or
techniques, thus, refer to the methods the
researchers use in performing research
operations.
Research methodology is a way to systematically
solve the research problem. In it we study the
various steps that are generally adopted by a
researcher in studying his research problem
along with the logic behind them.

Observation Observational behaviour
scale, score cards
Case Study &
Life History
Cross-sectional collection of
data, Longitudinal collection
of data
Survey Questionnaire, Schedules,
Opinionnaire

11. Process of Research

12. Research Process:
Research Process consists of series of actions or
steps necessary to effectively carryout research.
1.Define research problem (nature& understanding )
2.Review of literature
3.Formulate hypotheses
4.Research design (sample design)
5.Collecting the data (execution)
6.Analysis of data (testing hypothesis)
7.Interpretation & report writing

14. Simple random sampling: is also known as
chance sampling where each and every item in
the population has an equal chance of inclusion
in the sample
Examples: Drawing names from a hat
Systematic Sampling: Select a random starting
point and then select every Kth subject in the
population
Ex: select every odd number in a class

15. Stratified Sampling: Divide the population into at
least two different groups with common
characteristic(s), then draw some subjects from
each group (group is called strata or stratum)
Cluster sampling: it involves grouping the
population and then selecting the groups or the
clusters rather than individual elements for
inclusion in the sample.
Area sampling: it is quite close to cluster
sampling; under this sampling first we divide
the total area into a number of smaller non-
overlapping areas

16. Convenience Sampling: it is also called as
deliberate sampling. This sampling involves
purposive & deliberate selection (Use subjects
that are easily accessible)
Judgement Sampling: The researcher chooses the
sample based on who they think would be
appropriate for the study.
Quota Sampling: A sampling method of gathering
representative data from a group.
