Collection of Data
Research is a process of knowing the unknown things for the betterment of humanity. In the process, explorations of the different sources of information are carried out by a researcher to expose the so long unexposed truth. Thus, information is the prerequisite for achieving the objectives of any research program. Information may be qualitative or quantitative/numerical. Data refers to different kinds of numerical information. In any research program, a researcher is always in search of a suitable mechanism/process for the collection of information. Thus, data collection plays a vital role in any research program. Depending upon the research design, in particular, the objective of a research program and the types of information required are fixed. The next task is data collection. Depending upon the sources of information, data may be (1) primary or (2) secondary.
