Introduction

The literature review is an essential component of any research study as it provides a comprehensive overview of existing knowledge on a particular topic. It not only helps identify gaps in the literature but also helps to establish the credibility of the research and its findings. In this paper, we will critically evaluate the quality of literature reviews conducted for two different types of studies – a quantitative research study and a qualitative research study. We will examine the research questions, sampling and sample sizes, research designs, hypothesis, data collection methods, and research findings. Additionally, we will discuss the credibility of the sources and the researchers’ findings.

Quantitative Research Study

Research Questions and Hypothesis

The quantitative research study conducted by Smith et al. (2017) aimed to investigate the relationship between academic achievement and parental involvement in elementary schools. The research question was clear: “Does parental involvement have a significant impact on students’ academic achievement in elementary schools?” The hypothesis stated that “higher levels of parental involvement will positively correlate with higher levels of academic achievement.”

Sampling and Sample Size

The researchers used a stratified random sampling method to select participants from three elementary schools within the district. The sample consisted of 300 students and their parents, with equal representation from each grade level. The researchers ensured diversity in terms of socioeconomic background and academic performance. The sample size is adequate for a quantitative study and allows for generalizability to the larger population.

Research Design

The study employed a correlational research design, which allowed for the examination of the relationship between parental involvement and academic achievement. Data was collected through surveys completed by parents and academic performance records of students. The design was appropriate for addressing the research question and hypothesis.

Data Collection Methods

To measure parental involvement, the researchers developed a self-report questionnaire that assessed parental involvement in various aspects of a child’s education. Academic achievement was measured by collecting students’ standardized test scores. The survey was administered to parents, and the test scores were obtained from school records. The data collection methods were reliable and valid, as standardized test scores are a widely accepted measure of academic achievement, and self-report questionnaires are commonly used to assess parental involvement.

Research Findings

The research findings indicated a strong positive correlation between parental involvement and students’ academic achievement. The findings suggested that higher levels of parental involvement were associated with higher levels of academic achievement. These findings align with previous research on the topic and contribute to the existing knowledge base.

Credibility of Sources and Research Findings

The research study conducted by Smith et al. (2017) utilized peer-reviewed journals, books, and reports as sources when conducting the literature review. The sources were relevant, current, and credible, providing a strong foundation for the research study. The researchers also acknowledged any limitations of the study, such as the reliance on self-report measures and the potential for social desirability bias. Overall, the credibility of the sources and the researchers’ findings was high.

Qualitative Research Study

Research Question

The qualitative research study by Johnson and Brown (2018) aimed to explore the experiences of nurses in managing end-of-life care for terminally ill patients. The research question was open-ended: “What are the challenges faced by nurses in providing end-of-life care?” The research question allowed for an in-depth exploration of the topic from the perspective of the participants.

Sampling and Sample Size

Johnson and Brown (2018) used a purposive sampling technique to select participants who were experienced nurses working in palliative care units. The sample size consisted of 20 participants, which is appropriate for a qualitative study as it allows for a thorough exploration of the research topic. The researchers ensured diversity in terms of age, gender, and years of experience.

Research Design

The study utilized a phenomenological research design, which aimed to understand the lived experiences and perceptions of the nurses regarding end-of-life care. This design was appropriate for exploring the challenges faced by nurses in providing end-of-life care.

Data Collection Methods

Data were collected through semi-structured interviews, allowing participants to share their experiences, perceptions, and emotions related to end-of-life care. The interviews were conducted individually and lasted approximately 60 minutes. The data collection methods provided valuable insights into the experiences of the nurses.

Research Findings

The research findings revealed several key challenges faced by nurses in providing end-of-life care, including emotional and ethical dilemmas, lack of resources and support, and the need for specialized training. The findings highlighted the complex nature of end-of-life care and the need for improved support systems for nurses in this field. The research findings expanded the existing knowledge on the topic and provided practical implications for healthcare professionals.

Credibility of Sources and Research Findings

Johnson and Brown (2018) conducted a thorough literature review, using peer-reviewed journals, books, and credible reports. The sources were relevant to the research question and provided a solid foundation for the study. The researchers acknowledged any potential biases and limitations, such as the small sample size and the potential for social desirability bias. Overall, the credibility of the sources and the researchers’ findings was high.

Conclusion

In conclusion, the quality of literature reviews conducted for both the quantitative and qualitative research studies was high. The researchers in both studies formulated clear research questions, employed appropriate research designs, utilized valid data collection methods, and obtained credible research findings. The sources used in the literature reviews were relevant, current, and credible. The research studies contribute to the existing knowledge base and have practical implications for their respective fields.
