An animated guide explaining how the standard devition can give you a clearer picture of a sample than averages alone. An example involving zoo keepers and some very dangerous animals demonstrates ...

Mean and variance of horizontal wind direction are defined in a minimal variance sense. Starting from a theoretical model, termed anisotropic Gaussian model, of the probability density functions of ...

For example, suppose that the manufacturing process described in the previous example produces engines whose weights are normally distributed with a mean of 1250 and a standard deviation of 12. The ...
