4. What is Research Design? What are the different types of Research Designs?
Research Design
The research designer understandably cannot hold all his decisions in his head. Even if he could, he would have difficulty in understanding how these are inter-related. Therefore, he records his decisions on paper or record disc by using relevant symbols or concepts. Such a symbolic construction may be called the research design or model. A research design is a logical and systematic plan prepared for directing a research study. It specifies the objectives of the study, the methodology and techniques to be adopted for achieving the objectives. It constitutes the blue print for the plan is the overall scheme or program of research. A research design is the program that guides the investigator in the process of collecting, analyzing and interpreting observations. It provides a systematic plan of procedure for the researcher to follow elltiz, Jahoda and Destsch and Cook describe, “A research design is the arrangement of conditions for collection and analysis of data in a manner that aims to combine relevance to there search purpose with economy in procedure.”
Components of Research Design:
It is important to be familiar with the important concepts relating to research design. They are:
1. Dependent and Independent variables:
A magnitude that varies is known as a variable. The concept may assume different quantitativevalues, like height, weight, income, etc. Qualitative variables are not quantifiable in the strictest sense of objectivity. However, the qualitative phenomena may also be quantified in terms of the presence or absence of the attribute considered. Phenomena that assumedifferentvalues quantitatively even in decimal points are known as “continuous variables. But, all variables need not be continuous. Values that can be expressed only in integer values are called” non-continuous variables. In statistical term, they are also known as „discrete variable.
