The closer the number is to zero, the fatter the tails. The closer the number is to 1 (it can never exceed 1!), the thinner the tails. For example, the normal distribution has a MAD/SD ratio of 0.7970, which happens to be the square root of 2 over pi (not a coincidence, try ... infinityfree cloudflare sslWebIn a skewed distribution, the median is often a preferred measure of central tendency, as the mean is not usually in the middle of the distribution.
