MEANING OF RESEARCH DESIGN
• Research design is a logical & systematic outline of research project prepares for directing,
guiding and controlling a research work.
• It acts as an broad outline of the research work.
• It is like road map which enables the researcher to conduct various research activities for
orderly completion of research project.
• In short it is a systematic planning, organising and executing a research project within
specified time limit and resource allocation.
FEATURES OF RESEARCH DESIGN
Similar to Blue Print
Orderly Execution
Reference Document
Plan, structure & strategy
Act as outline of research work
Offers guidance at all levels

Design
5) For the collection of relevant data
for research project
6) To access expenses
7)To motivate the staff
8) For improved decisions
1) It provides appropriate guidelines
to researcher
2) It facilitates organising of resources
for collecting data
3) In order to give suitable directions
to the researcher staff
4) Selection of appropriate techniques
for data collection & data analysis
Importance of Research Design
 Blueprint
 Right track
 Avoid errors
 Proper Planning
 Higher efficiency
 Right use of resources
 Defines relationship
 Successful journey
 Time schedule Removes uncertainty

Scope of Research Design
 Sources of data collection
 Methods of data collection
 Methods of data analysis
 Data collection specific
 Availability of physical resources
 Need for qualified staff
 Time allotment
 Population for research
 Decision on sample size
FACTORS AFFECTING RESEARCH DESIGN
• Non-availability of qualified staff
• Availability of sufficient data
• Availability of resources
• Availability of time
• Nature & scope of study
• Impact of variables
• Impact of resources plan
• Regulator of research work
• Exposure to source of data
ESSENTIALS OF GOOD RESEARCH DESIGN
Simplicity
Flexibility
Focus on objectives
Cost effective
Element of suitability
Pilot study
Smooth administration
Systematic approach to research design
Training to research staff
Adopt right methods
MEANING OF:-
Sample
Sample means a small portion of the
population taken up for intensive
study purpose.
It is a small part of the entire
population having similar
characteristics of the population.
Sample selected act as a representative
of the whole universe.
Sampling
Sampling is the process of selection of
certain percentage of a whole group of
items as per determined plan.
Sampling is a better choice from the
point of view of time & money.
It is a process of selecting a small
representative group from the whole
for intensive study purpose.
