RESEARCH DESIGN

RESEARCH DESIGN

The research problem having been formulated in clear terms, the researcher will be required to prepare a research design, i.e. he will have to state the conceptual structure within which research would be conducted.


The preparation of such a design facilitates research to be as efficient as possible yielding maximal information.


But how all these can be achieved depends mainly on the research purpose. Research purposes may be grouped into four categories, viz.,


(i) Exploration

(ii) Description

(iii) Diagnosis

(iv) Experimentation

• flexible research design, which provides opportunity for considering many different aspects of a problem, is considered appropriate if the purpose of the research study is that of exploration.
  
• But when the purpose happens to be an accurate description of a situation or of an association between variables, the suitable design will be one that minimizes bias and maximizes the reliability of the data collected and analyzed. There are several research designs, such as, experimental and non-experimental hypothesis testing.
  
  
• Experimental designs can be either informal designs (such as before-and-after without control, after-only with control before-and-after with control) or formal designs (such as completely randomized design, randomized block design, Latin square design, simple and complex factorial designs), out of which the researchers must select one for his own project.
  
  
  
• The preparation of the research design, appropriate for a particular research problem, involves usually the consideration of the following:

(i) the means of obtaining the information

(ii) the availability and skills of the researcher and his staff (if any)

(iii) explanation of the way in which selected means of obtaining information will be organized and the reasoning leading to the selection

(iv) the time availability for research and

(v) the cost factor relating to research, i.e. the finance available for the purpose.

Hey there,

I read your article on Research design and really liked it. I am also uploading a document where you will get more information Research Design in B2B International.
