Description
The aim of this programme is to show how statistical techniques can be used in designing an experiment. The problem considered in this programme is effect of lysine on the growth rate of young chic...ks. It is known that lysine increases growth, but although lysine is contained in wheat, the growth of chicks fed with wheat appears to be lower than expected. At Lane End Farm in the University of Reading an experiment was performed to confirm this finding, and to examine the hypothesis that the reduced growth rate is caused by the inhibitory effect of other amino acids present in wheat. The features of this experiment considered in the programme are the double Latin square design used to take account of systematic variations in the experimental environment, and the analysis of variance table which is used to derive an estimate of the inherent variation in chick weights.
