✦ Synopsis

I n ecological studies experiments are often designed in which the variables to be compared are not statistically independent. Examplea include repeated measures of the same response by the same individual a t different timea, measurement of several traits on the same individual, and measurements taken from two or more types of organisms present together in the same experimental unit (e.g.) plot, cage: pond, etc.). This type of design violates several assumptions of the standard enalyaie of variance. Theae assumptions are examined and profile analysis. a modification of the standard analyeis of variance which does not depend upon these assumptions, is presented. Simple instructions for performing profile analysis of variance using two common statistical packages for mainframe computers are provided in an appendix.
