Radiology Alliance for Health Services Research (RAHSR)/Radiology Research Alliance (RRA) On-line Statistical Webinar Series

A robust knowledge of biostatistics is important for designing and conducting high-quality radiology research. As the complexity of research increases, there is a growing and urgent need for academic radiologists to acquire fundamental skills in biostatistical methods. Each Webinar was previously recorded live and can be accessed below using YouTube.

Individual Comparisons (Parametric and Non-parametric)
Presenter: Andrew B. Rosenkrantz, MD

This two-part webinar covers individual statistical comparisons (both parametric and non-parametric). Content includes characterizing the nature of your data, selecting the right statistical test, and obtaining p-values. Tests that investigators can perform themselves, as well as pitfalls and caveats in obtaining and interpreting p-values, are highlighted. Examples of covered statistical tests, along with numerous case examples, include paired and unpaired t-tests, the Wilcoxon and Mann Whitney tests, Fisher's exact test, and the McNemar test.


Introduction to Probability and Statistics for Diagnostic Testing and Research
Presenter: William F. Auffermann, MD, PhD

This webinar provides an overview of the basic aspects of probability and statistics needed to critically appraise and perform research. Fundamental concepts of probability and statistics are covered to provide a foundation for further study.

 The RAHSR/RRA Webinar Series is supported by a Venture Fund Grant
from the AUR Research and Education Foundation
