BBA RESEARCH METHODOLOGY Need of Research Design
Need of Research Design:
According to P.V. Young, a research design should be able to provide answer to the following queries:
(i) What is the study about and what type of data are required?
(ii) What is the purpose of the study? What is its scope?
(iii) What are the sources of the needed data?
(iv) What should be the place or area of study?
(v) What time, approximately, is required for the study?
(vi) What should be the amount of material or number of cases for the study?
(vii) What type of sampling should be used?
(viii) What method of data collection would be appropriate?
(ix) How will the data be analyzed?
(x) What should be the approximate expenditure?
(xi) What would be the methodology of study?
(xii) What should be the specific nature of study?
Keeping in view the aforesaid design decisions, the researcher may split the overall practical research design into the following phases:
(a) The sampling design, dealing with the method of selecting items to be observed for the given study;
(b) The observational design, specifying the conditions under which the observations are to be made;
(c) The statistical design, taking into account the quantitative and statistical aspects of the design which concerns with the questions of how many items are to be observed and how the information and data gathered are to be analyzed.
(d) The operational design, relating to the use of specific technique for the operation of the model already designed. It deals with the techniques by which the procedures specified in the sampling, statistical and observational designs can be carried out.
