Literature review is a written body of text that accounts what already has been published about the topic as contributed by other researchers (Taylor n. d.). Literature review describes the scientific discoveries that have been done which are relevant to the research that is going to be conducted. This allows the researcher to be in a good perspective on how his research can be done appropriately in light of all the knowledge that has already been acquired about the topic of interest. It therefore prevents redundancy of repeating something that has been proven correct or incorrect already.
It also enables the researcher to determine the gaps in knowledge by finding out what areas still need to be studied in his topic. It then allows advancement in the area of study, as the researcher appropriate his objectives and methods according to the current status of research in his subject. Survey research is “ one of the most important areas of measurement in applied social research which encompasses any measurement procedures that involve asking questions of respondents” (Trochim 2006). It provides a good assessment of how people think about or feel about a particular subject.
Thus, analyses and evaluations of a social topic can be drawn from a valid source of information. This method of research consists of predetermined sets of questions that are to be asked to a group of people called sample. In doing such, the researcher collects information from a population that comes from his sample. Depending on what the researcher is trying to find out, survey research enables him to answer those questions through a collective answer from his sample set. Literature review in survey research provides an understanding on where the focus of the research must be.
It enables the researcher to support the research that he is going to embark by laying out all the facts from previous discoveries relevant to his topic.
