Abstract

The literature review is an essential component of any research study as it provides a comprehensive overview of existing knowledge and research gaps in the field. This critique will evaluate the quality of literature reviews conducted for two different types of studies, a quantitative and a qualitative research. The research questions, sampling and sampling sizes, research designs, hypothesis, data collection methods, and research findings will be analyzed and discussed. Additionally, the credibility of the sources and the research/researchers findings will be assessed.

Introduction

The literature review is a crucial step in the research process as it helps to identify existing theories, concepts, and gaps in knowledge regarding the research topic (Petticrew & Roberts, 2008). A well-conducted literature review builds a strong foundation for the research study and ensures that it is grounded in existing evidence. This critique will assess the quality of literature reviews conducted for a quantitative and qualitative research study and discuss various aspects such as research questions, sampling and sampling sizes, research designs, hypothesis, data collection methods, and research findings. Additionally, the credibility of the sources and the research findings will be evaluated.

Quantitative Research Study

The literature review of the quantitative research study is comprehensive and thorough. The authors have identified and critically evaluated a wide range of relevant studies published in reputable journals, which contributes to the credibility of their research. Additionally, the use of recent literature published within the last three to five years strengthens the relevance of the study.

The research question in this quantitative study focuses on examining the relationship between two variables, X and Y. The authors outline a clear research question that is focused, specific, and answerable through quantitative methods. This aligns with the purpose of a quantitative study, which aims to quantify and measure variables (Leedy & Ormrod, 2018).

The sampling method used in this study is a non-probability sampling technique, specifically convenience sampling. Although this method may limit the generalizability of the findings, it is a common approach in quantitative research to obtain a large sample size efficiently (Petticrew & Roberts, 2008). The sample size is adequately justified based on power analysis calculations, ensuring that it is sufficient to detect the hypothesized effect size.

Regarding the research design, the study employs a cross-sectional design, which is appropriate for investigating relationships between variables at a specific point in time (Leedy & Ormrod, 2018). However, this design does not allow for causal inferences. The hypothesis is clearly stated and predicts a significant positive relationship between variables X and Y, based on existing theories and evidence from prior studies.

The data collection method in this study involves the use of a structured questionnaire administered to participants. While this method allows for efficient data collection and analysis, it may limit the depth of understanding of participants’ experiences, opinions, and perspectives (Leedy & Ormrod, 2018). The reliability and validity of the questionnaire are adequately addressed, with appropriate measures taken to ensure the quality of data.

The research findings are presented clearly and concisely, using appropriate statistical analyses to address the research question. The results are supported by statistical significance tests and effect sizes, enhancing the credibility of the findings. Overall, the literature review in this quantitative research study is of high quality, providing a solid foundation for the research and demonstrating methodological rigor. The research findings are credible and contribute to the existing body of knowledge in the field.

Qualitative Research Study

The literature review in the qualitative research study is thorough and well-conducted, providing an in-depth understanding of the research topic. The authors have identified and critically analyzed a range of qualitative studies, ensuring that the research is grounded in existing evidence. The use of recent literature also strengthens the relevance and credibility of the study.

The research question in this qualitative study aims to explore the experiences, perceptions, and meanings associated with a specific phenomenon. The question is open-ended and allows for a deeper exploration of participants’ thoughts and experiences (Creswell, 2013). This aligns with the purpose of a qualitative study, which focuses on understanding individuals’ subjective experiences and meanings.

The sampling method employed in this study is purposive sampling, specifically maximum variation sampling. This method allows for the selection of participants who represent a wide range of perspectives and experiences related to the research topic (Creswell, 2013). The sample size is justified based on theoretical saturation, ensuring that data collection stops when no new information is being obtained.

Regarding the research design, this study utilizes a phenomenological approach, aiming to explore the lived experiences and perceptions of participants (Creswell, 2013). This design allows for an in-depth exploration of the research question but does not aim for generalizability. The hypothesis is not applicable to qualitative research, as it focuses on understanding the subjective experiences and meanings of participants.

The data collection method in this study involves in-depth interviews with participants, allowing for a rich and detailed exploration of their experiences and perceptions. This method allows for a deeper understanding of participants’ lived experiences but may be time-consuming and resource-intensive (Creswell, 2013). The credibility of the research findings is enhanced through member checking and the use of an audit trail, ensuring trustworthiness and dependability of the data.

The research findings are presented clearly, providing rich descriptions and direct quotations from participants to support the interpretations. The findings are analyzed thematically, in line with qualitative research methods, allowing for the identification of patterns and themes (Creswell, 2013). The research findings are credible and contribute to an enhanced understanding of the research topic.

Conclusion

In conclusion, this critique has evaluated the quality of literature reviews conducted for a quantitative and a qualitative research study. The literature review in the quantitative study demonstrates methodological rigor, providing a strong foundation for the research. The research findings are credible and contribute to the existing body of knowledge. Similarly, the literature review in the qualitative study is thorough and well-conducted, allowing for an in-depth exploration of the research topic. The research findings are credible and provide rich descriptions of participants’ experiences. In both studies, the credibility of the research/researchers’ findings is enhanced through appropriate sampling methods, research designs, data collection methods, and rigorous analysis.
