Research Design
CHAPTER III
RESEARCH DESIGN
Meaning – Need – Features – Steps In Formulating a Research Design – Basic Principles of Experimental Designs
Once the Research problem identified, researcher has to plan how to go about the / conduct research in most efficient and successful manner.
Good planning gives the researcher direction for the successful completion of the project
The plan of study is called research design
It the blue print of the proposed study
MEANING
“It is a logical and systematic planning and it helps directing a piece of research”
R.D is the program that guides the investigator in the process of collecting, analyzing and interpreting observation
A plan of what data to gather, from whom, how and when to collect the data, and how to analyze the data obtained
A plan for collecting and utilizing data so that desired information can be obtained with sufficient precision or so that an hypothesis can be tested properly.
1. What is the study about
2. Why is study being made
3. What type of data are needed
4. What are the sources of data
5. What periods pf time will the study include
ESSENTIALS OF A GOOD RESEARCH DESIGN
1. It should minimize the biasness and maximize the reliability
2. Lower the experimental error better design / a design which yield nominal information
a. It facilitates obtaining required information
b. It suits to the skill of the researcher
NEED FOR A RESEARCH DESIGN
1. It act as a guide to the researcher (compass in the hands of sailor)
2. It makes research process effective minimum use of time, money
3. It act as a blue print for the purpose of data collection
4. It also indicates the techniques of data collection
5. It helps the researcher to collect the data according the objectives of research
6. Therefore the R.D increases the reliability of the research finings
7. Without R.D a study lead towards misleading conclusions
8. so it is necessary
