ABSTRACT
The primary data comes handy when the objective of the researcher is to add new insight into the problem. The researcher collects the first-hand information from the participant by asking questions regarding his experience on the problem under investigation. Observation is about sensing the background information and the information which is present in hand. Indirect observation is required in some situations because our interaction can disturb the setting. Self-administered techniques are best suited for studies in which it is easy to assess the participants and the research site is under the researcher’s control. Email and telephone calls are best suited for situations where our respondent is busy, fixing the meeting in the office is difficult, contacting corporate offices (which generally are at important and big cities), or the respondent is at a distant location where it is not easy to approach.
