The case study method has advantages and disadvantages in quantitative research. On the one hand, case studies are criticized for generating less generalizable results compared to large-sample, quantitative methods . This limitation is mainly observed in within-population generalization. However, case studies have merits in terms of theoretical generalization, identifying disconfirming cases, and providing useful information for assessing empirical generalizability . Additionally, case study analysis is advantageous in illustrating the connection between theory and practice . It allows for a deeper understanding of complex phenomena and can explore problems that traditional quantitative methodologies may not address effectively . On the other hand, case studies may be limited in terms of sample size and representativeness, which can affect the external validity of the findings . Furthermore, case studies require careful consideration of the quality of the research and the role of theory in the analysis .

What are the benefits of using quantitative research?5 answersQuantitative research offers various advantages, including the ability to reach a higher sample size, quick data collection, and the generalizability of findings. It involves the systematic investigation of a research topic by collecting quantifiable data and conducting mathematical and statistical manipulations to produce meaningful conclusions. Additionally, quantitative methods provide insights into research processes, enhance understanding of scientific proposals, and are fundamental for data management in various professional areas. In the field of mental health, quantitative research is crucial for studying the incidence of mental health problems, understanding their reasons, evaluating services, and informing mental health policy decisions. Overall, quantitative research methods play a vital role in generating reliable and statistically supported knowledge across different disciplines.What are the advantages and disadvantages of qualitative vs quantitative research methods?4 answersQualitative research methods offer unique insights into local-level perspectives and are valuable for understanding complex economic issues and decision-making. On the other hand, quantitative research methods are often preferred for their precision and reliability. Qualitative research allows for openness to diverse research approaches and questions, making it adaptable to the unpredictability of economic life. However, qualitative methods have faced criticism and rejection from scholars who favor quantitative approaches. Quantitative research, with its focus on numerical data, is advantageous for statistical analysis and generalizability but may lack the depth of understanding provided by qualitative methods. Ultimately, both qualitative and quantitative methods have their strengths and weaknesses, and the choice between them should be based on the specific research objectives and the nature of the phenomena being studied.Why quantitative method?4 answersQuantitative methods are valued in various fields because they provide numerical estimates that can lead to insightful and valid scientific conclusions. These methods are particularly useful in domestic violence and abuse (DVA) settings to inform practice, policy, and research. In applied linguistics, quantitative research methods (QRM) are widely practiced and contribute to answering questions systematically. Forensic toxicology laboratories frequently use quantitative analytical methods to derive the amount of a substance present in a biological specimen, ensuring rigorous method validation and quality control. In language instruction, quantitative methods help researchers objectively compare the effectiveness of different approaches, using statistical techniques such as repeated measures analysis. Quantitative tools, including mathematical models, are also valuable in economic science and decision-making support systems, providing better understanding and management of complex social and economic phenomena.When the best to use the quantitative research methods?4 answersQuantitative research methods are best used when there is a need for standardized and robust approaches to patient follow-up evaluation, especially for research purposes. These methods provide an objective and reproducible way of interpreting imaging data, allowing for accurate assessment of treatment response and changes in disease severity. Additionally, quantitative analysis can improve the characterization and quantification of disease, leading to better diagnosis and management of diffuse lung diseases. However, it is important to note that qualitative research methods also have their place, particularly when exploring unique phenomena or gaining a deeper understanding of subjective experiences. Therefore, the choice between quantitative and qualitative research methods should be based on the research question and the specific goals of the study.Why we use quantitative study?5 answersQuantitative study is used because it allows researchers to uncover meaning through objective analysis of collected data. It provides information in large numbers and is considered more reliable due to its use of statistical methods. Quantitative research is used to quantify attitudes, opinions, behaviors, and other variables, and to generalize results from a larger sample population. It is a systematic way of investigating phenomena and their relationships, with the goal of explaining, predicting, and controlling a phenomenon. Quantitative study designs are specific, well-structured, and have been tested for validity and reliability. They ensure accuracy in measurement and classification by using structured, rigid, fixed, and predetermined study designs.What are the benefits and limitations of using a quantitative research method in evaluation studies?5 answersQuantitative research methods offer several benefits in evaluation studies. They allow for the characterization and quantification of the overall impacts of implementation strategies on various outcomes. These methods provide accurate and reliable measurements that enable statistical analysis. They also help in determining the most appropriate statistical test for follow-up analyses. Additionally, quantitative methods allow for the integration of qualitative data, providing a more comprehensive evaluation. However, there are limitations to using quantitative research methods in evaluation studies. The statistical properties of genuine strategies can be indistinguishable from random strategies, leading to potential false discoveries. Insufficient samples and changing market conditions can limit the power of the test and affect the effectiveness of quantitative claims. Furthermore, quantitative methods may not capture the complexity and meaning of actions in a given context, which is better addressed by qualitative methods.
