3. • Descriptive studies may
sometimes serve as a starting
point for hypothesis generation
or theory development.
4. FEATURES
• Descriptive designs are used to
observe, document and describe
a phenomenon occurring in its
natural setting without any
manipulation or control.
5. • Descriptive studies are designed
to gain more information about
characteristics within a select or
a particular field of study.
• Descriptive studies provide a
picture of a situation as it occurs
in natural setting.
6. • The design does not involve the
manipulation of variables.
Variables are studies as they
exist in the natural world.
7. • Descriptive research designs are
used to develop theories,
identify problems with current
practices, make judgments or
determine alternative solutions
for the existing practices.
8. • In case of descriptive studies bias
is prevented through operational
definitions of variables, by
choosing a large sample size, by
using random sampling
techniques, By means of using a
valid & reliable tools of
measurement, & formal data
collection procedures.
9. • Descriptive designs include
identification of a phenomenon
of interest, identification of
variables within the
phenomenon, developing
operational definitions of the
variables & describing the
variables.
10. • Thus through descriptive designs
description of variables leads to
an interpretation of the
theoretical meaning of the
findings and development of
hypothesis.
13. • The design does not focus on the
study of a single variable.
• Two or more variables are
studied.
14. • The basic purpose of this design
is not only to describe each of
the variables, but also to
establish the relationship
between two variables.
15. • This design is primarily used to
identify and describe the
perception, awareness,
behaviour, attitude, knowledge,
practices of people.
16. EXAMPLE
• A study to assess the
experiences of patients suffering
from Leprosy.
17. • In this study the researcher may
describe the frequency of
different symptoms experienced
by the patients and types of
treatment they received.
19. • It is an in-depth exploration and
study of the related factors to
improve further understanding
about a less understood
phenomenon.
20. EXAMPLE
• An exploratory study to assess
the multi-factorial dimensions of
falls and home safety measures
for elderly people living in
selected communities in the city
of Chennai.
21. COMPARTIVE DESIGN
• Comparative research designs
are involved in comparing and
contrasting two or more samples
of study subjects on one or more
variables at a single point of
time.
22. • This research design is used to
compare two distinct groups on
the basis of selected attributes
such as knowledge & attitude,
etc.,
23. EXAMPLE
• A comparative study on health
practices among rural and urban
older people in Moolakulam,
Puducherry.
