What is research design? Explain its significance

Introduction : 

    Preparation of a research design is an indispensable task for proceeding in the field of social research. Perhaps the most direct impact of research procedure upon theory has resulted from the creation of sociological statistics organised in term of theoretically pertinent categories. Talcott Persons has observed that numerical data are scientifically important only when they can be fitted into analytical categories and that a great deal of current research has producing facts in a form which according to Talcott Persons, cannot be utilised by any current generalised scheme.

    A research design is the arrangement of conditions for collection and analysis of data in a manner that aims to combine relevance to the research purpose with economy in procedure. In fact it is the conceptual structure within which research is conducted. It constitutes the blue print for the collection, measurement and analysis of data. As such the research design includes an outline of what the researcher will do from writing the hypothesis and its operational implication to the final analysis of data.

Research design :  

    A researcher attempting to solve his problem, should necessarily prepare a plan which will help him to attain his ultimate  motto. This plan is nothing but a research design.

    According to Pauline V. Young, a research design is "the logical and systematic planning and directing a piece of research." The design, according to her "result from translating a genera scientific model into varied research procedures." It gives an outline of the structure and process of the research programme. Without such a plan of study, no scientific study is possible.

    The design may be a specific presentation of the various steps in the process of research. These steps include the selection of a research problem, the presentation of the problem, the formulation of the hypothesis, conceptual clarity, and methodology, survey of literature and documentation, bibliography, data collection, teasing of the hypothesis, interpretation, presentation and report writing.

    Research design is the plan, structure and strategy of investigation conceived so as to obtain answer to research question and to control variance. The plan is the overall-scheme or programme of research. It includes an outline of what the investigator will do from writing the hypothesis and their operational implications to the final analysis of the data. The structure of research is the outline, the scheme and paradigm of operations of variables strategy includes the methods to be use to gather analyse the data. In other words, strategy implies how the research objectives will be tackled. 

    First, it is plan that specifies the sources and types of information relevant to the research question. Second, it is a strategy or blueprint specifying which approach will be used for gathering and analyzing the data. Finally since most business research studies have time and economic constraints, both time and cost budgets are typically included.
