In the realm of research, particularly in health and social sciences, understanding the intricacies of power and sample size is crucial for designing effective studies. The Coursera course titled “Power and Sample Size for Multilevel and Longitudinal Study Designs” offers a comprehensive five-week journey into this essential aspect of research methodology.
**Course Overview**
This fully online course delves into innovative, research-based methods for power and sample size analysis, specifically tailored for multilevel and longitudinal studies. It is designed for researchers and practitioners who wish to enhance their skills in statistical analysis and improve the quality of their research designs. The course is structured into five weeks, each focusing on different aspects of power and sample size analysis.
**Week 1: Introduction to Multilevel and Longitudinal Designs**
The course kicks off with an introduction to the fundamental concepts of multilevel and longitudinal studies. Participants are guided through basic statistical concepts, including hypothesis testing, which lays the groundwork for the more complex topics to come. The introduction to GLIMMPSE software is particularly beneficial, providing a hands-on approach to conducting power and sample size analyses.
**Week 2: Foundations of Complex Designs**
In the second week, the course dives deeper into research design, exploring critical considerations such as type 1 and type 2 errors, variance, and correlation structures. This module emphasizes the importance of aligning research designs with appropriate statistical tests, ensuring that participants are well-equipped to tackle real-world data analysis problems.
**Week 3: Model Assumptions and Missing Data**
The third week addresses the assumptions underlying multivariate and mixed models, as well as the challenges posed by missing data. This module is particularly relevant for researchers who often encounter dropout rates or data entry errors, providing strategies to adjust sample sizes accordingly.
**Week 4: Inputs to Analysis and Recruitment Feasibility**
Week four focuses on the various inputs for power and sample size analysis, including empirical literature and pilot studies. The discussion on recruitment feasibility is invaluable, as it highlights the socio-demographic factors that can impact study participation. This week culminates in an independent exercise that reinforces the learning objectives.
**Week 5: Ethics and Funding**
The final week addresses the ethical considerations of sample size analysis, emphasizing the importance of planning to avoid overpowered or underpowered studies. Participants learn how to structure sample size sections in grant proposals, enhancing their chances of securing funding. The course concludes with peer reviews and a final exam, solidifying the knowledge gained throughout the course.
**Recommendation**
Overall, this course is a must for anyone involved in health-related or social science research. It not only equips participants with essential statistical skills but also emphasizes the ethical implications of research design. The practical exercises and real-world examples make the learning experience engaging and applicable. Whether you are a novice researcher or looking to refine your skills, this course will undoubtedly enhance your understanding of power and sample size analysis.
