Standard deviation, or lower case sigma, measures the spread, or deviation, of data about a central tendency, such as the mean or the median in a data set or group, with a Gaussian (bell curve) distribution. Standard deviation is a widely used measure of variability or diversity used in statistics a...
New research out today reveals that the Alpine Fault - a strike-slip fault running almost the entire length of the South Island - is surprisingly "well-behaved" in its regularity. But good behaviour, in a scientific sense, may not bring much comfort to South Islanders. In earthquake te...
