A few youtube clips that may help you understand EBCP concepts better

1. Risk:
http://www.youtube.com/watch?v=4LMTnLGwoF4
This is a nice little introduction to the concept of risk in medical literature. The author uses a simulated study to help illustrate concepts here.

2. Confidence Intervals:
http://www.youtube.com/watch?v=Hn6C21GC0vA&feature=related And here is a presentation which clarifies understanding of confidence intervals, another key concept in reading and interpreting medical literature.

3. Sample Size Calculation:
http://www.youtube.com/watch?v=HuGl50C8Q30&feature=related
Here the idea is to know how many subjects you need in a study to be able to achieve statistical significance.

4. Regression Analysis:
http://www.youtube.com/watch?v=JPjW2HPTaEw&feature=related
This is a common procedure used in statistics but not one everyone necessarily understands. This little clip does a nice job of explaining what this is.

5. Evidence-Based Medicine 1:
http://www.youtube.com/watch?v=QsIYwWwi_r4
An introduction to the topic, looking at critical appraisal.

6. Evidence-Based Practice: http://www.youtube.com/watchv=SWMjkxNpl6k&feature=related
This is about the real world applications of EBCP.

7. Research Methods:
http://www.youtube.com/watch?v=0FyCTupSdXM
A primer on beginning research.

Beyond this, so much more exists on youtube that can help explain concpets related to evidence-based practice, to teaching effectiveness and to scholarship. Poke around, and enter what I have called a "youtube fugue..."
