Normal distributions have key characteristics that are easy to spot in graphs: 1. The mean, median and modeare exactly the same. 2. The distribution is symmetric about the mean—half the values fall below the mean and half above the mean. 3. The distribution can be described by two values: the mean and the … See more All kinds of variables in natural and social sciences are normally or approximately normally distributed.
