Abstract: MUCH of the rapid progress achieved through research in the field of chick nutrition has been founded upon experimental results in which treatment differences were large and often very striking. As a greater and greater portion of new nutritional research involves further refinements in diets, differences between treatments become smaller and more difficult to ascertain with reasonable reliability. The purpose of this paper is to demonstrate the magnitude of experimental errors found in the usual chick nutrition trial and to reiterate the need for adequate experimental designs and analyses. The author became interested in the problem of experimental errors in chick nutrition trials in 1951 and began assembling data from as many laboratories as could be found with data appropriate for analysis. The very comprehensive paper by Homeyer and Pauls (1954) led the writer to believe that perhaps further effort was not warranted, since it seemed that the pertinent problems …
