Concise, readable, and easy to navigate—a practical and thorough guide to conducting efficient and effective medical research

A Doody's Core Title for 2024 & 2023!

Whether you’re a student, scholar, faculty member, or practicing healthcare professional Research Methodology in the Health Sciences helps you improve your research skills and critically appraise original research and apply it in evidence-based patient care. This peerless guide describes the principles of biostatistics and provides detailed examples to build your comprehension of the utility and applicability of bio-statistical tests, without going into the mathematical details of such tests.

You’ll find accessible coverage of the principles of biomedical ethics in research and publication, review of the medical literature, how to write a dissertation, how to prepare and submit a research manuscript for publication in a journal, how to apply for a research grant to funding agencies, and much more. To enhance the learning process, all examples drawn exclusively from real healthcare scenarios.

Research Methodology in the Health Sciences covers:

Planning a research studyWriting a dissertationTypes of studies in clinical researchObservational and interventional studiesApproaches to qualitative researchEthics in medical researchBiostatistics and descriptive statisticsApproaches to statistical inference
