We should also attempt to identify known or expected sources of variability in the experimental units since one of the main aims of a designed experiment is to reduce the effect of these sources of variability on the answers to questions of interest. A 4x4 Latin square may be too small to give sufficient power to the experiment, but a single experiment could involve two or more such squares. Factor, a factor of an experiment is a controlled independent variable; a variable whose levels are set by the experimenter. The natural structure arises from the fact that individual rats may differ in their responses and/or there may be time effects associated with the in-vitro culture. Methods of reporting discussed. Blinding In a medical experiment, the comparison of treatments may be distorted if the patient, the person administering the treatment and those evaluating it know which treatment is being allocated. The Latin square design This design can increase the power of the experiment above that of the randomised block design by removing two possible sources of heterogeneity such as body weight, day or time of day, litter, position in the animal house etc. A statistical analysis of these data using minitab uses a two-way anova, given below. Of more interest would be the percent to the total variation accounted for by the treatments, which is 21764.2/24272.9.7. A randomised design is obtained by randomising whole rows followed by randomising whole columns.

This involved humanely killing a rat, preparing the thymocytes, and adding them to petri dishes with a suitable cell culture medium. That is, we design the experiment in order to improve the precision of our answers. The cosi - foil to Lewis members of each block are then randomly assigned to different treatment groups. However, they can be replicated so that a single experiment could involve two 4x4 Latin squares. The "subject" in this case was a cage with two C57BL/6 mice with two drinking bottles. The normal probability plot is a reasonable good straight line, and the plot of fits versus residuals shows no evidence that the variation is heterogeneous,.e., there is no particular pattern to the residuals. The scores are shown in the table.
