Understanding Benford's Law with Numberphile

Brady from Numberphile discusses an analysis of video statistics to see if they follow Benford's Law. Initial analysis of Numberphile videos shows a poor match, possibly due to a small sample size. A larger dataset from all his channels shows a better fit to Benford's Law for view counts and comments. Viewers are encouraged to think about why durations don't fit and to engage in the comments.
