In this brief video, the presenter discusses, ideas from my paper on the advantages of the mean deviation. The issue of whether the simpler mean deviation or the more complex standard deviation is to be preferred, when representing the variability of a measurement, was debated almost 100 years ago. The standard deviation has since been preferred by statisticians. But since my paper, and as described in my new SAGE book, the use of the mean deviation has grown dramatically in areas as distinct as genetics, library studies, artificial intelligence, and physics.
