It is often the task of a social scientist to examine the nature of the distribution of some variable character in a large population. This entails the determination of values of central tendency and dispersion usually, the arithmetic mean and the standard deviation. Other features of the distribution, such as its skewness, its peakiness (or the so-called kurtosis), and a measure of its departure from some expected distribution may also be required.
