Explain the Numerical Taxonomy?

Numerical methods in taxonomy are not new. Simple statistical methods like standard deviations, t-tests and chi-squared have been used for several years. Recently with development of electronic digital computers, numerical analysis of a large quantity. of taxonomic data in a relatively short period of time has become possible. This has led in the last twenty years to the development of a new branch of taxonomy called numerical taxonomy or taxometrics.

The computation of data by evaluating numerically the affinity or similarity between organisms and then ordering them into tax takes very little time, probably a few seconds. However, the preparation of the data in a suitable form for input into the computer is a very tedious task requiring painstaking examination and recording of information.
