experimental animals
animals kept expressly for the purposes of conducting experiments on them. Called also laboratory animals.
experimental design
the method of allocating experimental units to treatment groups in an experiment; many complicated and sophisticated designs are available, e.g. balanced, unbalanced, crossover, factorial, randomized, non-random, split-plot.
experimental epidemiology
the study of changes effected in populations by changes made in the factors affecting their performance, behavior or health.
experimental model
