One such video can be viewed here and illustrates the absolute and relative risks associated with mammography. They are attempting to demystify statistics and better explain the risks and benefits by showing an animated theater filled with 1,000 women, and showing how many women actually have their lives saved by mammograms (see screen shot below)...
...as well as the number of women who received false positives over the course of a life time...

This video touches on the confusion about relative versus absolute risk as well as the actual effectiveness of preventative medicine (and why it is so important to conduct efficacy research for medical interventions). I have a few discussion days with my Honor students and a discussion board with my online students that involve this piece from fivethirtyeight.com that questions whether methods of early cancer detection save lives or just uncover non-cancerous variation within the human body. This topic leads to lively discussions.
How to use in class:
-Medical examples (and I have plenty of pre-medical professional students)
-An example of why we teach our students to make graphs and charts. Sometimes, data is better shared via illustration
-Using statistics to inform important real-life decisions
