Introduction to medical statistics
This material was originally produced to support a course for students taking undergraduate and masters courses in dentistry. It is intended as an introduction to statistics for clinicians; the aims and objectives of the course and a short bibliography are given on the course outline page.
A glossary of some statistical terms is available. Finally, there are a few example exam questions provided for students to practice on.
