A literature review is quite significant for conducting any research successfully. It gives detailed and thorough prior information regarding the topic understand so that a good opinion can be formulated on the researched topic. We can gather a vast range of information using the literature of previous researchers and experimentation. Moreover, the literature provides verified information regarding your variables by cultivating the topi with extensive aspects. However, literature must be relevant enough to cover the topic variables to cater to gaps encountered while writing the literature for research. Sometimes the insufficient information and implications result in gaps in the literature of the study. Here below are the literature gaps.
Evidence Gap
The gap is mainly encountered when systematic evidence is missing in the literature. This means that the literature is quite descriptive and providing mere generic information regarding the variables of the topic. The coursework writing service firm, the evidence gap in the literature review aims to find out the logic and rationale of the study through evidence. Also, the literature provides adequate evidence of whether the topic is feasible for every type of population or not. Moreover, the evidence gap in the literature systematically portrays all the evidence regarding the topic, and upon that evidence, the researcher demonstrates the gap.
The empirical evidence provides the systematic review with respect to the variables by probing all the prior researches. The literature incorporates all the evidence from the relevant studies to make the literature review more authentic and precise. Also, the evidence makes the research more solid and reliable. Further, the literature provides a gap in the various evidence studies of the literature. The gap is the area upon which the researcher will conduct the study.
Practical Knowledge Gap
The gap encounter when there is a conflict between knowledge and factual data. When the past researches lack practical knowledge, the past researches do not have enough solid work regarding real-time practices and academic knowledge. Moreover, the literature that focuses on theoretical knowledge is not solid to be concluded as authentic research. Practical knowledge literature gap encounter when the prior research is only done on the academic contents whereas the researcher totally overlooks the practical aspects. This mostly happens when the systematic review is done by taking the qualitative and secondary studies in nature.
The literature lacks significant perspectives when the study only emphasises theoretical knowledge and literature. However, technical researches particularly demand a practical literature review to make research effective. Otherwise, the research is not considered competent enough to be called authentic if the literature lacks real-time analysis. Therefore, it is necessary to ensure that the research incorporated in the literature has some primary research.
Methodological Gap
The gap is seen in the literature when the set of methodologies are not defined in the research. The researcher in this gap lacks the proper methodology formulation before searching the information. The Phd dissertation writing service company says that past research has an insufficient methodological process because their approaches, designs, and techniques are not defined. Therefore, the researcher is not confident and switching the methodological process throughout the literature. Moreover, by probing the researches of previous studies, you find various gaps in a different section of research. The methodological gap in the literature is presented when the prior studies have not chosen adequate design, approach, and other data collection methods in their research. Moreover, the researcher suggests that the other chosen methodology would be more appropriate for the study in the methodological gap.
The gap lessens the intensity of research as the literature where the investigator is priorly on secondary data but later shifted to quantitative approach with uncertain population can increase the methodological gap in the study. Make sure the opted studies use the balanced framework and methodology approaches to reduce methodological errors in the literature. An integration of irrespective literature where a researcher has not defined its methodological and keeps switching the designs is not reliable to be included in the literature.
Theoretical Gap
The gap finds out the theoretical shortcomings in the prior literature. Moreover, the theoretical gap critically goes 
through the different literature of authors to evaluate their opinions regarding similar models or theories. So that a better review can be formulated based on compare and contrast with respect to the variable models. The gap can be highlighted by analysing the previous research along with their classical forms. Moreover, how the model demonstrates the variable and how it works depicts the theoretical gap more appropriately. The difference between the actual implementation and classical knowledge is the theoretical literature gap.
The gap can be deliberately explained in the literature by contrasting the theory and its current implications by different authors. The recent literature studies on the theories of variables must incorporate the practical implications that mitigate the theoretical gap in the literature. The gap highlights the shortcomings and other aspects with respect to previous studies on variables.
Empirical Gap
The literature in empirical gap aims to find the original work and revelations of authors that have worked on the particular variable theory, model or study. The literate keenly observes all the literature on the work of a particular author to gather information regarding the topic. The empirical gap focuses on the origin of literature rather than only gathering data on the variables of the study. The empirical literature is strongly based on overcoming the evaluation gap in the study. All the literature is evaluated properly before incorporating it into the research.
The topic particularly of social sciences opts for the empirical literature because the nature of variables demands literature gap to be fulfilled through empirical investigation by probing literature from its classic authors. The evaluation will be difficult to conduct if the topic variables do not have sufficient experimental literature in the prior studies.
