PhD Thesis - Chapter 2

the Literature Review of a PhD thesis is written as a critical discussion of existing studies related to your research topic... it is not merely a summary of previous research; rather, it analyses, compares, synthesizes, and evaluates the literature to demonstrate what is already known, what remains unknown, and how your study addresses the identified gap...

Literature Review Paragraph

several studies have examined the relationship between [Variable A] and [Variable B] in various contexts... for instance, Author (year) found that [key finding], suggesting that [interpretation]... similarly, Author (year) reported that [finding], highlighting the importance of [concept] in influencing [outcome]... however, contrasting findings were observed by Author (year), who argued that [different finding] due to variations in research context and methodology... these inconsistencies indicate that the relationship between [Variable A] and [Variable B] remains inconclusive... furthermore, most existing studies have focused on [specific population or setting], with limited attention given to [your research context]... consequently, there is a need for further investigation to better understand [research issue] and to provide evidence within the context of [your study area].
