BBA RESEARCH METHODOLOGY Basic Purposes of Research Design
Basic Purposes of Research Design:
From what has been stated above, we can derive two basic purposes:
(a) To provide answers to the research questions,
(b) To control variance. Indeed, these research purposes are achieved by the researcher himself, not by the research design.
As regards the first purpose, a research is designed to enable the researcher to arrive at an objective, accurate, valid and economic solution of the given problem to the maximum possible extent. Since scientific research begins with a provisional supposition in the form of a hypothesis, the major purpose of the design is to provide the research with a valid test of the hypothesis on the basis of empirical evidence obtained by the researcher by utilizing the least amount of money, manpower and time and maximum possibility of its being approved by other investigators engaged in the given area of investigation.
By providing a sort of blue print for the variation of hypothesis, presuming the relation between two or more variables on the basis of empirical facts and by directing the process of observation in terms of determining the facts relevant to the research problem, how and where to look for them and how many observations to make, the research design becomes indispensable on the part of any researcher in scientific investigation.
Furthermore, it also indicates whether or not the variables of the research are to be manipulated or selected, what specific values of the manipulated or selected variables are to be utilized in the scientific investigation, how a conceptual variable can be converted into observable facts.
