I have registered for a couple of courses but from reviews and comments of others, here are three online statistics courses for medical research you should consider:
Coursera: Introduction to Probability and Data by Duke University (https://www.coursera.org/courses/intro-to-probability-and-data): This course provides a comprehensive introduction to probability and data analysis, making it a great choice for those with little to no prior knowledge of statistics. The course is taught by experienced statisticians and provides a solid foundation for medical research.
EdX: Biostatistics: Concepts and Methods by Harvard University (https://www.edx.org/learn/biostatistics): This course is designed for students with a background in biology or medicine who want to gain a deeper understanding of biostatistics. It covers important concepts and methods in biostatistics, including hypothesis testing, regression, and survival analysis.
DataCamp: Clinical Trial Design (https://www.datacamp.com/courses/clinical-trial-design): This course is specifically designed for medical researchers and covers the design, conduct, and analysis of clinical trials. The course is taught through interactive tutorials and real-life examples, making it a practical and accessible choice for those looking to gain a deeper understanding of clinical trial design.
I selected these three courses because they each cover key concepts and methods in medical statistics that could easily be grasped by newbies. In addition, they are taught by reputable universities and organizations. The interactive format of these courses makes it easy for students to learn and apply the concepts in real-life situations.
I see that you are a clinician who'd like to more literate in statistic matters. I suggest you start with browsing e-book "statistic for dummies". That book filled with a lot of laymen's terms, therefore you shouldn't be afraid of greek's symbols and kinda.
