Different Research Designs • Experimental, Historical & Inferential RD • Exploratory, Descriptive & Causal RD • True Experimental, Pre-experimental, Quasi Experimental & Non-experimental • Historical Clinical & Case Studies
Different Perspectives of RD • • • • • • •
Degree of formulation of the problem Topical Scope-breadth & depth of Study Research Environment Time Dimension Mode of Data Collection Manipulation of variables under study Inter se relationship between variables
RESEARCH DESIGN IS RELEVENT AT EVERY STAGE OF RESEARCH PROCESS
Research design Definition (Elitz, Jahoda,Destch) • A Research Design is An arrangement of conditions For collection and analyses of data In a manner that aims To combine relevance To the Research purpose With economy in procedure
What is the need of a Research Design • Level of Accuracy or say level of tolerance with regard to inaccuracy is ascertained • To detail out procedure that will be adopted to carry out a Research
Characteristics of a Good RD • Is a series of guide posts to keep one going in the right direction • Reduces wastage time and costs • Encourages co ordination and effective organization • Is not rigid undergoes modifications as circumstances demand • Has to be geared up to the availability of data and co operation of the informants
Components Variable A magnitude that varies is known as a Variable • Dependent & Independent Variables • Quantitative & Qualitative Variables • Continuous & Non-continuous Variables
Confounded Relationship • • • •
