Metrics & Indicies, whats the difference?

.wellboy · 2012-12-14 19:46:16

Are metrics just single measurements of something (eg. Species richness) and idicies are many metrics combined to give a measurement? Any help would be much appreciated.

Only seeing this now - sorry if its too late. I'm assuming since you posted in the Env. Sci. forum that by indices you are referring to those found in ecology.

Both are types of quantitative measurement. However indices (e.g. Simpsons, Shannon, species richness etc.) are unitless and are generally derived from data (such as population counts etc.) using a given equation whereas a metric is a generic term to describe most quantitative (and some qualitative) measurements (e.g. height, weight, age).
