Research is the process of searching for knowledge. It is systematic search pertinent information on specific topic of interest. It is a careful investigation or inquiry especially through search for new facts in any branch of knowledge .It is a scientific way of getting answers for research questions and testing hypothesis. The research question is based on uncertainty about something in the population. This can be formulated by searching different literatures from index and non index journals, books, internet, and different unpublished research work etc. A good research question should follow the FINER criteria i.e. Feasible, Interesting, Novel, Ethical and Relevant .
The complete research is the whole design which arises from defining research problems to the report writing (Figure 1). The research problems are determined on the basis of well known concept and theories or previous research findings. The assumptions in term of hypothesis are made. The process of inquiry is done by interviewing or observing or recording data and the collected data are analyzed with interpretation. Basically there are two approaches of data collection, quantitative and qualitative. The quantitative approach views human phenomena as being focused to study objective i.e. able to be measured. It has its roots in positivism. Quantitative approach to research involves data collection methods such as structured questionnaire, interviews and observations together with other tools. This approach helps investigators to quantify the information.
